Rotor moment of inertia J [kgcm²]
Measure of the acceleration capacity of the motor. For example, at

from 0 to 3000 rpm can be calculated
based on the following formula:

Thermal time constant t
TH
[min]
Specification of the heating time of the cold motor under load with I
0
until an overtemperature of 0.63 x 100 Kelvin is reached. This tem-
perature rise happens in a much shorter time when the motor is
loaded with the peak current.
Release delay time / application delay time of the
holding brake t

[ms]/t
BRL
[ms]
Specification of the response times of the holding brake [+] when
operated with the nominal voltage
