AM8000 and AM8500
Voltage constant K
Erms
[mVmin]
Indication of the induced motor EMF at 20 °C, based on 1000 rpm.
This is specified as the sine RMS value between two terminals.
Rotor moment of inertia J [kgcm²]
Measure of the acceleration capacity of the motor. For example, at
J
0
the acceleration time t
b
from 0 to 3000 min-1 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 brake t
BRH
[ms]/
t
BRL
[ms]
Specification of the response times of the holding brake [+] when
operated with the nominal voltage
Winding inductance L [mH]
Indication of the motor inductance. It is the average value for one
motor revolution, with two energized phases, at 1 kHz. Saturation of
the motor must be taken into account.
