Required motor torque
The required motor torque M
the torque specifications must always be taken into account.
M = M

M : Frictional torque
r
Determining the required motor torque
The frictional torque characteristic can be determined on the basis of the speed characteristic.
The total formula can then be used to create the motor torque-time diagram (see diagram
below) from which the required peak torque M

is always the sum of the individual torques. The sign in front of
