DC gear motors

Dc gear motors diameter 63 interaxis 35 gmr63-35-z4


Stall torque from 21,2Nm to 6,70Nm

The GMR63-35-Z4 gear motors are equipped with filter. The rotor shaft has a worm with four threads.

The filter, generally made of an LC-circuit, allows the electric motors to be tested in compliance with the EMC norms.

In the technical data-sheet it is possible to select the output gear shaft and to request a particular set of cables by inserting it in the enquiry form.

In the table “Electric Data” one can see the application voltage range and the performances for the most commonly used voltages, 12V and 24V.

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


The electric GMR63-35-Z4 gear motors are used in linear actuators, in garage door openers and in automatisms of various kind.

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).
