DC Brush Motor
A DC Brush Motor is a rotating motor that contains a brush device to convert DC electrical energy into mechanical energy (DC motor) or convert mechanical energy into DC electrical energy (DC generator). Unlike DC brushless motors, brush devices are used to introduce or introduce DC voltage and DC current. DC brushless motor is the foundation of all motors, which has the characteristics of fast start, timely braking, smooth speed regulation over a large range, and relatively simple control circuit.
Classification of composition of DC Brush Motor
The basic components of a DC brushless motor include a stator, rotor, brush, and commutator.
The interaction between the stator and rotor magnetic fields drives the motor to rotate. The types of brushless DC motors are classified based on the way the magnetic field is generated in the stator or casing of the motor. According to the type of brushless DC motor, the stator magnetic field can be generated by permanent magnets or windings in the stator. For the latter case, the stator winding and rotor winding can be connected in parallel, serial, or hybrid mode. These three types of brushless DC motors are called parallel excited motors, series excited motors, and compound excited motors.
Principle of DC Brush Motor
The stator generates a static magnetic field.
This stationary magnetic field surrounds the armature (or rotor). The external power source excites the armature magnetic field. There are also two circular copper plates on the shaft of a DC brushless motor, called reversing plates. When the motor rotates, the carbon brush slides on the commutator. This can generate a rotating magnetic field that is attracted to the stationary magnetic field of the stator. The current in the armature and stator windings is supplied by batteries or other DC power sources (permanent magnet DC brushless motor motors do not have stator windings). The battery (or DC power supply) provides a constant DC voltage. The voltage amplitude determines the speed of the motor, so the battery or DC power supply is a linear excitation source. The most effective way to change the speed of a DC brushless motor is to use pulse width modulation (PWM) technology. PWM technology switches a constant voltage source at a fixed frequency. Changing the pulse width of the PWM signal can adjust the speed of the motor. The proportion between the high and low levels of pulses is called the duty cycle of the PWM signal. The amplitude of the DC battery level is equal to the average amplitude of the PWM signal.
