Gear motors

SOLID AND RELIABLE

GEAR MOTORS FOR DOMESTIC AND PROFESSIONAL USE

SERIES MR 330

These motors are characterized by their compact dimensions, high flexibility and extremely high quality,

guaranteed by a careful choice of materials and great attention in the manufacturing stage.

OPERATION

The Milano Componenti MR 330 Series of gear motors offers a wide range of models for both continuous

and intermittent duty.

In particular for the intermittent duty, there are some solutions:

Normal intermittent duty at 50%: 10” ON and 10” OFF

Reduced intermittent duty at 30%: 6” ON and 4” OFF

Base time for intermittent duty is 20 seconds and the MR 330 Series gear motors for intermittent usage are

available in the self-locking model: AB version, usually with a horizontal shaft. This AB model enables the

elimination of rotor inertia, by acting against the inertia of the units to which the gear motor is applied and

cancelling any active load torque.

The ambient temperature must be between 10°C and 80°C, observing the over-temperature limits laid down

by current regulations for windings. Prior to regular running, it is therefore necessary to carry out winding

over-temperature tests on the motor mounted on the equipment, by selecting the most severe duty cycle.
