Configuring the motor
5.1 Procedure
no longer purely sinusoidal. As a result, the torque generated by the motor is no longer
uniform but instead has a ripple. The extent to which the maximum speed can be
overridden depends on the permissible following error and positioning error in the
controller as well as the motor type.
● Motor with different winding
Several winding variants are available for some motor sizes. Windings with lower
inductance allow higher speeds with the same motor size and maximum torque. One
drawback here, however, is the higher motor current.
● Larger motor type
If the first two solutions are not feasible, a motor with a higher peak torque must be used
to ensure that sufficient torque reserves are available for the required torque M

5.1.8
More than one torque motor on one axes
If the torque motors on the same axes are operated on separate drive systems with separate
angular position measuring systems, the rotation-angle-related alignment of the individual
stators with respect to each other and the individual rotors with respect to each other is
irrelevant.
Electrical parallel connection
If the motors are operated on the same drive system (electrical parallel connection), the
individual rotors must be precisely aligned with each other when they are mounted on the
axes. The individual stators must also be precisely aligned with each other when they are
installed (see "Parallel operation of more than one motor").
5.1.9
Checking the moments of inertia
Once a suitable motor has been selected, the moment of inertia of the rotating mass on the
axis has been determined. This value can be used to check the assumptions made
regarding the duty cycle.
