Planetary gear motors diameter 77_p_81 m77x60-h_pm81ln

M77x60-H_PM81LN

Stall torque from 5354,0Nm to 8,87Nm

The M77x40-H motors are equipped with filter, with one or two Hall sensors and have higher performances than the M77x40-H motors thanks to longer rotor and magnets. The PM81LN planetary gearboxes have both toothed wheels and housing made of plastic.

Longer rotor and magnets allow to increase the maximum torque, thus improving the efficiency under load, while the Hall sensors supply 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 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 circuit with one or two Hall sensors and to request a particular set of cables or a special output gear shaft, different from the represented standard, by indicating them in the requirements form.

In the “Electric Data” table is indicated the range of working voltages of M77x40-H_PM81LN planetary gear motors and are listed the performances for the most commonly used voltages, 12V and 24V.

The interactive curve allows to choose the required performances by selecting the power voltage, no-load speed and the gear ratio at one, two or three stages.

Applications

The M77P-H_PM72LN planetary gear motors are used in linear actuators and in automatisms of various kind.
