■
Application
The water-cooled SIMOTICS M-1FE built-in motors are used in
combination with the SINAMICS S120 drive system for applica-
tions that require the highest quality of machining, accuracy and
running smoothness, as well as very short ramp-up times.
There are two main versions of SIMOTICS M-1FE built-in motor
available:
•
High Torque series
6-pole/8-pole and 16-pole synchronous motors are available
that have been developed for turning and grinding machines
with moderate maximum speeds.
These motors are characterized by a very high torque
utilization. In this case, the speed range is approximately 1:2.
•
High Speed series
In this series, 4-pole synchronous motors are available for
milling. These motors are optimized for high maximum speeds
and a speed range of over 1:4.
■
Design
The SIMOTICS M-1FE built-in motor comprises:
•
A laminated, permanently excited rotor, which, as an option,
can be designed with a sleeve for simple mounting and
removal.
•
A wound stator core with cooling jacket and encapsulated
winding overhang.
- Free cable ends, length 0.5/1.5 m (1.64/4.92 ft)
-
Two integral PTC thermistors (incl. 1 reserve), optionally with
full or universal protection
- A cooling jacket into which the stator has been inserted
Rotor with sleeve
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 rotor with sleeve is pre-balanced and can be removed
and subsequently remounted. The bond can be released by
pressure-oil injection without affecting the joint surfaces.
Rotor without sleeve
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.
Removal of the rotor is not possible with this type of mounting.
Rotors without sleeves are not pre-balanced.

Technical specifications
A Voltage Protection Module (VPM) is required for certain motor
types if they are operated up to maximum speed.
