How does a DC motor work in an electric actuator for industry

How a DC motor works in an industrial actuator

Learn how 12 V and 24 V DC motors are used to convert electric energy into mechanical movement in modern industrial actuators and become familiar with the most common motor parts, such as brushes, gears, and permanent magnets.

If you want to learn how components, such as motor brushes, the commutator, the permanent magnets, and the electromagnetic coil all work together to generate the movement of a permanent magnet DC motor, our man Hunter Stephenson explains the essentials in this video.

A Direct Current (DC) motor, is a rotary machine that converts electric energy into mechanical energy. This functionality is based on the principle of induction – an electromagnetic force created by input current, which in turn creates a rotational movement.

The efficiency of a DC motor is the relationship between the input power and the output power, measured in Watt. Many of the motor parts have an influence (reducing impact) on the motor’s efficiency, resulting in generated heat. This also applies to very high or low surrounding temperatures that are often part of the working environments of industrial actuators.

However, there are ways to ensure a high motor efficiency for DC gear motors in general.

In order to achieve optimal motor performance, you need a stable power supply, and you must ensure the right cabling and input voltage as these are equally important to obtaining the best efficiency possible. If you would like to know more about the factors influencing the motor efficiency, check out the video above.
