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 Watts. 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 they are equally important to obtain the best efficiency possible. If you would like to know more about the factors influencing motor efficiency, check out the video above.
