DC Electric Motors for the agricultural sector: comfort and safety in Agricultural Applications
GMR-77-43-Z1-B-X-H
Stall torque from 43,80Nm to 132,00Nm
The GMR-77-43-Z1-B-X-H gear motors are not equipped with filter, they have a circuit with one or two Hall sensors and the brushes can be replaced. The rotor shaft has a worm with one thread.
The Hall sensor supplies a signal which allows to count the number of rotations made by the motor. With two Hall sensor it is possible to determine also the rotation direction of the electric motor.
The replaceable brushes allow a longer life to the motor and they can be replaced by removing the plastic part screwed to the brush-holder.
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.
