SIMOTICS T-1FW6 built-in torque motors with jacket cooling (left), natural cooling (middle) and with integrated cooling (right)

SIMOTICS T-1FW6 built-in torque motors are liquid-cooled or naturally cooled, multi-pole permanent magnet AC synchronous motors with hollow-shaft rotor. The motors are supplied as built-in components that are held together in the delivered state by transport locks. For a complete drive unit, an additional bearing and shaft encoder are required.

Each frame size is available in different axis lengths. Most stators and rotors are equipped with flanges at each end with centering surfaces and threaded holes for installation in the machine.

Please note that when SIMOTICS T-1FW6 direct motors (torque motors) are used in fork heads for machine tools or robots, a license for US patent US5584621 and the associated international patent protection may be required. Please observe the national and international licensing conditions when using direct motors so that no infringements of industrial property rights occur.

Область применения

In conjunction with the SINAMICS S120 drive system, the SIMOTICS T built-in torque motors can be used as direct drives for the following machine applications:

Rotary indexing machines
Rotary tables and splitters
Rotary axes (A, B, C axis in 5-axis machine tools)
Turret indexing and cylinder indexing for single-spindle and multi-spindle machines
Tool spindles
Roller and cylinder drives
Infeed and handling axes
Tablet presses
Medical equipment
Measuring machines

Дизайн

The SIMOTICS T-1FW6 built-in torque motor comprises the following components:

Stator

Version in 3-phase AC winding. The stator is generally designed for operation with liquid cooling.

Rotor

Cylindrical hollow shaft made of steel with permanent magnets fixed to the circumference.

If the main cooler and precision cooler are used together in a cooling unit, a cooling connection adapter (accessory) can be ordered separately for simpler connection.

Cooling types

The design of the cooling system is dependent on the size (external diameter) of the motor.

SIMOTICS T-1FW6 built-in motor Type	Type of cooling
1FW6050 and 1FW6060	Integrated water cooling with one cooling circuit
1FW6053 and 1FW6063	Natural cooling
1FW6090 ... 1FW6150	Jacket water cooling
1FW6160 ... 1FW6290	Integrated water cooling with two cooling circuits

Naturally cooled motors

Naturally cooled motors have the same dimensions as watercooled motors in frame sizes 1FW6050 and 1FW6060, but have a lower continuous torque capability because they are naturally cooled. They can be used for any application for which liquidcooled motors would be deemed undesirable or unnecessary. In addition to their dimensions, their mechanical interfaces are also compatible with those of water-cooled motors which means that it is relatively easy to change the cooling method.

Components of naturally cooled motors in frame sizes 1FW6053 and 1FW6063 (rotor and stator)

Motors with integrated single-circuit cooling

These motors have a ready-to-connect, integrated single-circuit cooling system; they are compact and therefore suitable for easy integration in a machine.

Motors with jacket water cooling

The coolant inlet/return flow circuit must be provided by the machine manufacturer in the surrounding construction.

Motors with integrated dual-circuit cooling

These motors feature a ready-to-connect, integrated dual-circuit cooling system and are therefore thermally insulated to a large extent against the mechanical axis construction.

Интеграция

The SIMOTICS T-1FW6 built-in torque motors supplied via the SINAMICS S120 drive system are designed for operation on a 600 V DC link voltage level.

The cable connection is brought out of the front face of the stator. The cable end has a pre-assembled connector or exposed cable cores depending on the motor version. The length of the power and signal cables from the motor to the drive system must not exceed 50 m (164 ft).

Absolute measuring systems with DRIVE-CLiQ

Measuring systems with integrated DRIVE-CLiQ interface are available from various manufacturers. The encoders can be used as motor feedback system.

The current overview of manufacturers and available measuring systems can be viewed on the Internet at:
