Thermal motor protection

The motor temperature is monitored by two sys-

tems that are operated independently of each

other. The mounted temperature sensor and the

drive-internal temperature model ensure the best

protection of motors against thermal overload.
MKE motors are protected against impermissible

heating by a PTC drilling integrated in the motor

winding.
A series circuit of three PTC thermistors (one

PTC resistor per string) is installed in each motor.

Triggering devices or control devices monitor the

resistance to a maximum value. Voltage discon-

nection occurs when only one PTC is heated up to

nominal tripping temperature (130

 

°C

±

5

 

°C) by

the winding.
