0.15 When is an electric motor used and when is a geared motor used?

electric motor

• It only provides the mechanical rotary motion.

• Suitable if the speed or torque is a direct match.

• Commonly used in pumps, fans, ventilators, and small machines.

• Advantages: simple, inexpensive, flexible in control (e.g. with frequency converter).

geared motor

• Combination of electric motor and gearbox.

• The gearbox reduces or increases the speed and optimally adjusts the torque to the application.

• Ideal for conveyor technology, conveyor belts, screw conveyors, elevators, cranes, machines with high load or precise rotational speed.

• Advantages: High adaptability to load, compact design, fewer additional components required.
  
  

In short:

• Electric motor: simple applications, direct driving force.

• Geared motor: for situations where speed, torque or compact design need to be specially adapted.
