Effect for asynchronous machines (ASM)
For asynchronous machines, the current is calculated from a complex current model. Here, both sat-

uration effects and voltage drops in the inverter are considered. The calculations in DSD may be as-

sumed adequately accurate up to a quadruple overload of the motor.

Radial and axial loads of the motor or gearbox shaft

Dependent on the mechanical design, radial (e.g. for belt outputs) and axial forces can act on the

motor or gearbox output shaft.

• The permissible limit values can be found in the catalogue of the component.
