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 100 K 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 A-side motor flange is intended for heat dissipation. If a gearbox
is attached, the heat dissipation is interrupted and reduces the
power of the motor.
By default, the engine heat via the A-flange is dissipated into the
machine bed. Due to heating of the gearbox, this is not possible for
thermal reasons. This configuration leads to a reduction of the rated
output.

Technical terms
This chapter provides information on various technical terms and
their meaning.
Standstill torque M
0
[Nm]
Torque, also referred to as starting torque, that the motor can gener-
ate at standstill. It can be maintained indefinitely at a speed n <
100 min
-1
and rated ambient conditions.
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:

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.
