Motor data
The motor data and characteristics are determined under the following
conditions:
● Ambient temperature 40 °C
● Insulated structure (aluminum flange)
● Amplifier temperature S-0-0384 = 100 °C (ΔT = 60 K); this temperature
is slightly higher than the temperature of the motor housing
● Switching frequency 4 kHz (at 8 kHz reduced continuous torque and
peak torque)
● Motors with radial shaft sealing ring
Operation modes
KSM02 motor-integrated servo drives are documented according to the test
criteria and measuring methods of EN 60034-1. The specified characteristics
correspond to operation modes S1 or S3.

Duty cycle
Operation mode S3 (intermittent duty) is supplemented by specification of the
duty cycle ED %. The duty cycle is calculated as follows:
