Technical data
Below you will find definitions of terms, environmental conditions,
operating details and technical data for the motors.
Definitions
Characteristic torque and speed curves
Detailed information on characteristic curves can be found at:
www.beckhoff.de -> Beckhoff motor curves
www.beckhoff.de -> TC Motion Designer
All data, with the exception of the voltage constant, are based on
40°C ambient temperature and 100K overtemperature of the wind-
ing. The data can have a tolerance of +/- 10%.
If a gear unit is attached the power may be reduced by up to 20%.
The flange of the motor used for heat dissipation is fitted with a gear
unit that generates heat during operation. The loss in performance
therefore has thermal reasons.
Technical term Symbol [Unit] Definition
Standstill torque M
0
[Nm] Torque, i.e. starting torque that the motor can output at a standstill.
Rotor moment of inertia J [kgcm²] Measure of the acceleration capacity of the motor. For instance, at J
0
the accelera-
tion time t

from 0 to 3000rpm is given as:

Winding inductance L [mH] Indication of the motor inductance. It is the average value for one motor revolution,
with two energized phases, at 1kHz. Saturation of the motor must be taken into ac-
count.
