Technical data
All data valid for 40 °C ambient temperature and 100 K overtemperature of the winding. The data can have a tolerance of +/- 10%.
If a gear unit is attached the power may be reduced by up to 20 %. This loss in performance has thermal reasons, since a gear unit that is subject to warming is installed at the motor flange intended for heat dissipation.
Term definitions
Standstill torque M0 [Nm]
The standstill torque can be maintained indefinitely at a speed n<100 rpm and rated ambient conditions.
Rotor moment of inertia J [kgcm²]
The constant J is a measure of the acceleration capability of the motor. For instance, at I0 the acceleration time tb from 0 to 3000 rpm is given as:
with M0 in Nm and J in kgcm2
Winding inductance L [mH]
The winding inductance indicates 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.
