Brush DC Motor Introduction
In a brush DC motor, the coil is located in the rotor, which rotates in the motor’s magnetic field. This rotation causes the current flow in the coil to alternate in direction as the commutator contacts the alternate brushes. It is this alternation of current direction in the coil that causes the rotor to keep rotating, thereby driving the motor.
Brush DC motors are divided into permanent magnet and electromagnet motors depending on the type of magnet used to provide the magnetic field.
Permanent magnet brushed DC motors are further divided into slotted, slotless, and coreless motors depending on the configuration of the armature (rotor).
Electromagnet brushed DC motors use electromagnets to generate magnetic flux in place of a permanent magnet. This configuration is used for motors with medium to high output. They are further divided into distributed-winding, series-wound, and separately-excited motors.
The advantages of brushed motors are their simple configuration and ability to operate without an electronic drive circuit in applications where speed control is not needed.
Applications for Brush Motor
DC motors are used in a wide range of applications, from familiar household appliances to large industrial plants. Brush DC motors in particular are among the most widely used of all types of electric motors, with uses ranging from the motors in toy models to auxiliary vehicle motors. Brushless DC motors also have a wide range of uses, including as components in the hard disk drives used to store data in PCs and in air conditioners, refrigerators, and other home appliances.
The choice of motor type depends not only on the application, but also on factors such as cost and maintenance. In terms of price, the requirement for an electronic circuit means that brushless DC motors tend to have a higher overall cost than brushed DC motors.
Brush DC Motors Work
All brush DC motors operate in the same way. First, an electric current is applied to the rotor, causing it to spin 180 degrees. To travel beyond this, the poles of the motor's electromagnet must switch. As the rotor spins, its attached carbon brushes come into contact with the stator, switching the magnetic field and allowing the rotor to rotate 360 degrees.
Brush DC motors typically operate at low speeds. They can be driven by a simple pulse width modulation (PWM) controller to vary the voltage supplied to the motor. This controls the speed in one direction and provides the torque needed for the motor to drive.
