Gearmotors: types, choice and applications

A gearmotor is the assembly consisting of an electric motor and a speed reducer, mounted together. The reducer reduces the motor speed to the value required by the application and, at the same time, increases the available torque. Gearmotors are the heart of industrial drives — from conveyor belts to mixers, agitators, cranes and process equipment. ProConsil Grup supplies the full range of industrial reducers and gearmotors, authorized distributor, with over 20 years of experience.

Types of gearmotors

According to the construction of the reducer, the main types are:

• Worm gearmotors — compact, high reduction ratio, quiet operation; ideal for high torque at low speed;
• Coaxial (cylindrical) gearmotors — high efficiency, coaxial input and output shaft;
• Bevel-cylindrical gearmotors — 90° direction change, high torque;
• Parallel shaft gearmotors — compact construction, flange or foot mounting;
• Planetary gearmotors — very high torque in a small footprint.

How to choose a gearmotor

For correct sizing you need:

• Output speed required by the application (rpm);
• Output torque required (Nm) — or the power and speed of the load;
• Service factor — operating mode (on/off, hours/day, shocks);
• Mounting position and the type of shaft (solid, hollow, flanged).

The reduction ratio results from the motor speed (e.g. 1500 rpm) and the desired speed. Our engineers will do the sizing for you free of charge and recommend the right gearmotor.

Gearmotor applications

Gearmotors drive belts and conveyors, augers, mixers and agitators, cranes and overhead cranes, packaging machines, extruders, dosing systems and much more — practically anywhere high torque at controlled speed is needed.

Frequently asked questions about gearmotors

What is the difference between a reducer and a gearmotor?

The reducer is just the transmission that reduces the speed; the gearmotor is the reducer + electric motor assembly mounted together, ready to use. We supply both versions.

What type of gearmotor do I choose?

Worm for compactness and high reduction ratio; coaxial for efficiency; conical-cylindrical for 90° direction change; planetary for high torque in a small footprint. It depends on torque, speed and mounting — we help you choose.

How do I calculate the discount ratio?

Ratio = motor speed divided by desired output speed. For example, a 1500 rpm motor and a required speed of 50 rpm means a ratio of 30:1. We calculate it based on your application.
