Configuring the motor
5.1 Procedure
Determining the required motor torque
The frictional torque characteristic can be determined on the basis of the speed
characteristic. The totals formula can then be used to create the motor torque-time diagram
(see diagram below) from which the required peak torque M
mMAX
can be read directly.

In addition to the peak torque M
mMAX
, the required continuous torque M
eff
of the motor is also
a crucial factor in determining how the motor is dimensioned. The continuous torque M
eff
responsible for the temperature rise in the motor can be derived from the motor torque-time
diagram by means of quadratic averaging and must not exceed the rated torque M
