DC electric motors

Dc electric motors diameter 42 standard m42


Stall torque from 0,76Nm to 0,23Nm

The M42 motors are electric motors equipped with noise-suppression filter.

The noise-suppression filter, which is normally made of an LC-circuit, allows the electric motors to be tested in compliance with the EMC directive.

In the technical datasheet it is possible to select the motor shaft and request a special wiring which has to be indicated in the enquiry form.

In the table named “Electrical Data” it is indicate the voltage range of the M42 motors’ applications and a list of the performances for the most commonly used voltage values, 12V ad 24V.

The interactive curve allows to select the required performances by selecting power voltage and no-load speed.



The M42 electric motors are generally applied in

linear actuators and in various automatisms.
