Характеристика

Typical speed/power graph for AC motors¹⁾

The graph shows the typical relationship between motor speed and drive power for SIMOTICS M-1PH2 motors for the following duty types in accordance with IEC 60034-1:

S1: Continuous duty

S6: Continuous duty with intermittent load and a relative duty factor of 60 % (S6-60 %) or 40 % (S6-40 %) with a maximum duty cycle time of 10 minutes.

Особенности

Compact design obtained by dispensing with mechanical components such as coupling, belt drive, gearbox and spindle encoder
High power density as a result of liquid cooling
The absence of drive transverse forces permits extremely high accuracy on the workpiece due to smooth, accurate spindle motion even at very low speeds
Extremely short ramp-up and braking times
Full rated torque is continuously available, even at standstill
Simple servicing by replacing complete motor spindles
Increased rigidity of the spindle drive, achieved by mounting the motor components between the main spindle bearings
C-axis compatibility with hollow-shaft measuring system mounted on the spindle
Low noise level due to absence of machine elements
Torque is transmitted to the spindle mechanically without play by means of a cylindrical stepped press fit. The rotor is mounted on the spindle by thermal shrinking. The bond can be released by pressure-oil injection without affecting the joint surfaces.
The rotor with sleeve is pre-balanced and can be removed and subsequently remounted
The rotor with sleeve is finished-machined - that is, the rotor outer diameter need not be finished after mounting.
