DC electric motors

Dc electric motors diameter 42 stronger version, with hall sensor m42p-h


Stall torque from 1,1Nm to 0,33Nm

The M42P-H motors are electric motors equipped with filter; they have higher performances in comparison with the M42-H motors thanks to longer rotor and magnets and are equipped with a circuit with one or two Hall sensors.

The longer rotor and magnets allow to increase the maximum torque, thus improving the under-load efficiency, while the Hall sensor provides a signal which allows to count the number of rotations of the motor. With two Hall sensors it is also possible to determine the sense of rotation of the electric motor. Thanks to the filter, which is normally  made of an LC-circuit, electric motors can be tested in compliance with the EMC directive.

In the technical datasheet it is possible to select the motor shaft, the circuit with one or two Hall sensors and to request special cables which have to be indicated in the enquiry form.

In the table named “Electrical Data” it is indicate the voltage range of the M42P-H 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 M42P-H electric motors are generally applied in linear actuators and in various automatisms.
