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.
APPLICATIONS
Vending machines

Ice makers
Ice-cream machines
Industrial rotisseries

GUIDE TO THE CHOICE OF THE GEAR MOTOR TYPE MR 330
To choose the model best suited to your requirements, identify:
Operating voltage and frequency
Required rotational speed
Torque needed, according to the duty type (continuous or intermittent), referring to Table 2
Preferred constructional solution, referring to the following figures
The table 1 defines the gear box dimensions in the different Constructional solutions (fig. 3)
Slow-speed shaft output. The gear motor can be purchased equipped with the standard shaft or in the
shaftless version (for application of client shaft).
