Technical definitions

Regulations, standards and specifications

The motors comply with the appropriate standards and regulations, see table below.

As a result of the fact that in many countries the national regulations have been completely harmonized with the international IEC 60034‑1 recommendation, there are no longer any differences with respect to coolant temperatures, temperature classes and temperature rise limits.

The motors listed below are UL-approved by Underwriters Laboratories Inc. and also comply with Canadian cUR standards:
SIMOTICS S‑1FK7/1FT7/SIMOTICS T‑1FW3/1FW6/SIMOTICS M‑1PH8 (without brake)/SIMOTICS L‑1FN3.

Degrees of protection for AC motors

A suitable degree of protection must be selected depending on the operating and environmental conditions to protect the machine against:

Ingress of water, dust and solid foreign objects
Contact with or approach to rotating parts inside a motor
Contact with or approach to live parts.

Degrees of protection of electric motors are specified by a code. This comprises 2 letters, 2 digits and, if required, an additional letter.

IP (International Protection)
Code letter designating the degree of protection against contact and the ingress of solid foreign objects and water

0 to 6
1st digit designating the degree of touch protection and protection against ingress of solid foreign objects

0 to 8
2nd digit designating the degree of protection against ingress of water (no oil protection)

W, S and M
Additional code letters for special degrees of protection

Most motors are supplied with the following degrees of protection:
Motor	Degree of protection	1st digit: Touch protection	Protection against foreign objects	2nd digit: Protection against water
Internally cooled	IP23	Protection against finger contact	Protection against medium-sized, solid foreign objects above 12 mm (0.47 in) ∅	Protection against spray water up to 60° from the vertical
Surface-cooled	IP54	Complete protection against accidental contact	Protection against harmful dust deposits	Splash water from any direction
	IP55	Complete protection against accidental contact	Protection against harmful dust deposits	Jet-water from any direction
	IP64	Complete protection against accidental contact	Protection against dust ingress	Splash water from any direction
	IP65¹⁾			Jet-water from any direction
	IP67¹⁾			Motor under specified pressure and time conditions under water

¹⁾ DIN VDE 0530 Part 5 or EN 60034 Part 5 specifies that there are only 5 degrees of protection for the first digit code and 8 degrees of protection for the second digit code in relation to rotating electrical machinery. However, IP6 is included in DIN 40050 which generally applies to electrical equipment.

Recommended degrees of protection for AC motors

When cooling lubricants are used, protection against water alone is inadequate. The IP rating should only be considered as a guideline in this case. The motors must be protected by a suitable cover where necessary. Attention must be paid to providing suitable sealing of the motor shaft for the selected degree of protection for the motor (for 1FT7: degree of protection IP67 and flange 0).

The table can serve as a decision aid for selecting the proper degree of protection for motors. With mounting position IM V3/IM V19/IM V6/IM V35 with shaft extension facing upwards, a permanent covering of liquid on the flange must be avoided.

Vibration severity and vibration severity grade A in accordance with IEC 60034‑14

The vibration severity is the RMS value of the vibration velocity (frequency range from 10 to 1000 Hz). The vibration severity is measured using electrical measuring instruments in compliance with DIN 45666.

The values indicated refer only to the motor. These values can increase as a result of the overall system vibrational behavior due to installation.

Vibration severity limit values for shaft heights 20 to 132

The speeds of 1800 rpm and 3600 rpm and the associated limit values are defined in accordance with IEC 60034-14. Speeds of 4500 rpm and 6000 rpm and the specified values are defined by the motor manufacturer.

The motors maintain vibration magnitude grade A up to rated speed.

Vibration severity limit values for shaft heights 160 to 355

Balancing in accordance with DIN ISO 8821

In addition to the balance quality of the motor, the vibration quality of motors with mounted belt pulleys and coupling is essentially determined by the balance quality of the mounted component.

If the motor and mounted component are separately balanced before they are assembled, then the process used to balance the belt pulley or coupling must be adapted to the motor balancing type. The following different balancing methods are used on motors of types SIMOTICS M‑1PH8:

Half-key balancing
Full-key balancing
Plain shaft extension

The letter H (half key) or F (full key) is printed on the shaft extension face to identify a half-key balanced or a full-key balanced SIMOTICS M‑1PH8 motor.

SIMOTICS S‑1FT7/1FK7 motors with feather key are always half-key balanced.

In general, motors with a plain shaft are recommended for systems with the most stringent vibrational quality requirements. For full-key balanced motors, we recommend belt pulleys with two opposite keyways, but only one feather key in the shaft extension.

Vibration stress, immitted vibration values

The following maximum permissible vibration stress limits at full functionality apply only to the SIMOTICS S‑1FT7/1FK7 permanent-magnet servomotors and SIMOTICA T‑1FW3 torque motors.

Vibration stress in accordance with DIN ISO 10816:

1 g at 20 Hz to 2 kHz

For all main motors of type SIMOTICS M‑1PH8, the following limits are valid for (immitted) vibration values introduced into the motor from outside:

Vibration frequency	Vibration values for 1PH808/1PH810/1PH813/1PH816

< 6.3 Hz	Vibration displacement s	≤ 0.16 mm (0.01 in)

> 63 Hz	Vibration acceleration a	≤ 4.0 m/s²(13.1 ft/s²)

For all torque motors of type SIMOTICS T‑1FW3, the following limits are valid for (immitted) vibration values introduced into the motor from outside:

Vibration frequency	Vibration values for 1FW3
< 6.3 Hz	Vibration displacement s	≤ 0.26 mm (0.01 in)
6.3 ... 63 Hz	Vibration speed V_am	≤ 7.1 mm/s (0.28 in/s)
> 63 Hz	Vibration acceleration a	≤ 4.0 m/s²(13.1 ft/s²)

Coolant temperature (ambient temperature) and installation altitude

Operation (unrestricted): -15 °C to +40 °C (5 °F to 104 °F)

The rated power (rated torque) is applicable to continuous duty (S1) in accordance with EN 60034-1 at rated frequency, a coolant temperature of 40 °C (104 °F) and an installation altitude of 1000 m (3281 ft) above sea level.

Apart from the SIMOTICS M‑1PH8 motors, all motors are in temperature class 155 (F) and utilized in accordance with temperature class 155 (F). The SIMOTICS M‑1PH8 motors are designed for temperature class 180 (H). For all other conditions, the factors given in the table below must be applied to determine the permissible output (torque).

The coolant temperature and installation altitude are rounded to 5 °C and 500 m (1640 ft) respectively.

Installation altitude above sea level	Coolant temperature (ambient temperature)
m (ft)	< 30 °C (86 °F)	30 ... 40 °C (86 ... 104 °F)	45 °C (113 °F)	50 °C (122 °F)

DURIGNIT IR 2000 insulation system

The DURIGNIT IR 2000 insulation system consists of high-quality enamel wires and insulating sheeting in conjunction with a solvent-free resin impregnation.

The insulating material system ensures that these motors will have a high mechanical and electrical stability, high service value and a long service life.

The insulation system protects the winding to a large degree against aggressive gases, vapors, dust, oil and increased air humidity. It can withstand the usual vibration stressing.

Motor protection

The KTY84‑130 temperature sensor is used to measure the motor temperature for converter-fed motor operation.

This sensor is a semi-conductor that changes its resistance depending on temperature in accordance with a defined curve. Siemens converters determine the motor temperature using the resistance of the temperature sensor. Their parameters can be set for specific alarm and shutdown temperatures.

The KTY84‑130 temperature sensor is embedded in the winding overhang of the motor like a PTC thermistor.

Starting in 2016, a new PT1000 temperature sensor will be phased in and will gradually replace the KTY84 sensor in the motors. Before the new sensor is released, all the relevant information will be made available at an appropriate time.

Sensors are evaluated as standard in the SINAMICS S120 drive system.

If the motors are operated on converters that do not feature a KTY84 evaluation circuit, the temperature can be measured with the external 3RS1040 temperature monitoring relay.

Built-in encoder systems without DRIVE‑CLiQ interface

For motors without an integrated DRIVE-CLiQ interface, the analog encoder signal in the drive system is converted into a digital signal. For these motors and external encoders, the encoder signals must be connected to SINAMICS S120 via Sensor Modules.

Built-in encoder systems with DRIVE‑CLiQ interface

For motors with an integrated DRIVE-CLiQ interface, the analog encoder signal is internally converted to a digital signal. There is no further conversion of the encoder signal in the drive system. The motor-internal encoders are the same encoders that are used for motors without a DRIVE-CLiQ interface. Motors with a DRIVE-CLiQ interface simplify commissioning and diagnostics because, for example, the encoder system is identified automatically.

The different encoder types, incremental, absolute or resolver, are all connected with one type of MOTION-CONNECT DRIVE-CLiQ cable.

Short designations for the encoder systems

The first letters of the short designation define the encoder type. This is followed by the resolution in signals per revolution if S/R is specified (for encoders without DRIVE-CLiQ interface) or in bits if DQ or DQI is specified (for encoders with DRIVE-CLiQ interface).

Absolute encoder, multi-turn

Multi-turn absolute encoder

This encoder outputs an absolute angular position between 0° and 360° in the specified resolution. In contrast to the multi-turn absolute encoder, it has no measuring gearbox and can therefore only supply the position value within one revolution. It does not have a traversing range.

²⁾ The single-turn absolute encoder is used for the previous incremental encoders.

Incremental encoder

This encoder senses relative movements and does not supply absolute position information. In combination with evaluation logic, a zero point can be determined using the integrated reference mark, which can be used to calculate the absolute position.

Incremental encoder IC/IN (sin/cos)

The encoder outputs sine and cosine signals. These can be interpolated using evaluation logic (usually 2048 points) and the direction of rotation can be determined.

In the version with DRIVE‑CLiQ interface, this evaluation logic is already integrated in the encoder.

Commutation position

The position of the rotor is required for commutation of a synchronous motor. Encoders with commutation position (also termed C and D track) detect the angular position of the rotor.

Resolver

The number of sine and cosine periods per revolution corresponds to the number of pole pairs of the resolver. In the case of a 2‑pole resolver, the evaluation electronics may output an additional zero pulse per encoder revolution. This zero pulse ensures a unique assignment of the position information in relation to an encoder revolution. A 2‑pole resolver can therefore be used as a single-turn encoder.

2-pole resolvers can be used for motors with any number of poles. With multi-pole resolvers, the pole pair numbers of the motor and the resolver are always identical, so that the resolution is correspondingly higher than with 2-pole resolvers.
