DC electric motors

Dc electric motors diameter 77 standard m77


Stall torque from 5,10Nm to 1,27Nm

The M77 motors are electric motors equipped with filter.

The 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 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 M77 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 M77 electric motors are generally applied in linear actuators and in various automatisms.

Set the characteristic curve

The characteristic curve of the DC electric motors is made of a diagram represented in the Cartesian axis based on the values which are inserted, where once can see represented the torque, in [Nm] (axis X); the rotation speed, in [Rpm] (axis y1); the absorbed current, in [A] (axis y2); the efficiency (axis y3).
