Definition of DC Motor

DC motor refers to a rotating motor that can convert DC electric energy into mechanical energy (DC motor) or mechanical energy into DC electric energy (DC generator). It is a motor that can realize the mutual conversion of DC electric energy and mechanical energy. When it operates as a motor, it is a DC motor, converting electric energy into mechanical energy; when it operates as a generator, it is a DC generator, converting mechanical energy into electric energy.

Comparison With AC Motors

The advantage of DC motors is that they are relatively simple to control speed. You only need to control the voltage to control the speed. However, this type of motor is not suitable for operation in high temperature, flammable environments, etc. Many direct-acting motors require carbon brushes as components of the current converter (DC brushed motors), so it is necessary to regularly clean the dirt generated by the friction of the carbon brushes. DC motors without carbon brushes are called DC brushless motors. Compared with brushless motors, brushless motors are more energy-saving and quieter because there is no friction between the carbon brushes and the shaft. They are more difficult to make and more expensive.

AC motors can operate in high temperature, flammable environments, etc., and there is no need to regularly clean the dirt on the carbon brushes, but it is more difficult to control the speed because controlling the speed of AC motors requires controlling the frequency of the AC power (or using induction motors, increasing internal resistance to reduce the motor speed at the same AC power frequency). Controlling its voltage will only affect the torque of the motor. The voltage of general industrial DC motors is AC 110V (125V) and AC 220V.

Brushed DC Motors

Brushed DC motors use an internal commutator (commutator), stator magnets (permanent magnets or electromagnets), and rotating electromagnets to generate torque from a DC power source.

The benefits of brushed DC motors are low initial cost, high reliability, and a simple way to control the speed of the motor. The disadvantages are high maintenance costs and a low life cycle under intensive use. Maintenance includes periodic replacement of the conductive carbon brushes and springs on the commutator, and the need to clean or replace the commutator. These devices are necessary to transmit external power to the motor.

Carbon brushes are generally made of carbon or graphite, and copper powder is sometimes added to increase conductivity. With use, the soft carbon brush material wears to conform to the radius of the commutator and will continue to wear. The brush holder has springs to maintain pressure on the brush as it shortens. If the brushes carry more than an amp or two of current, there are flying wires placed in the brushes and connected to the motor terminals. Very low-power motors use sliding contacts on the metal brush holder to conduct the current to the brushes, or contact springs press against the ends of the brushes. In very low power, short life motors (such as those in toys), folded metal strips in contact with the commutator are used as brushes.
