Brushed DC (BDC) motors get their name from the brushes that are used for commutation. Because its speed and torque are proportional to the applied voltage and current, a BDC motor is easy to control. BDC motors are cost-effective, easy to design in and simple to control, making them suitable for use in a wide variety of applications. Our microcontrollers (MCUs), gate drivers and single-chip motor drivers enable you to create compact, robust and efficient brushed DC drives.

Some Basics About Brushed DC Motors


How a Brushed DC Motor Works

  • Typically, the rotor, also known as the armature, has windings that terminate on a commutator
  • Brushes make and break contact with commutation segments to commutate power to the armature
  • The stator, or outer cylinder, of a permanent magnet DC motor has two or more magnets
  • The opposite polarities of the energized winding and the stator magnets attract, causing the rotor to rotate until it is aligned with the stator
  • As the rotor comes into alignment, the brushes move across the commutator contacts and energize the next winding

Brushed DC Motor Characteristics

  • Good controllability: on/off, proportional
  • Linear torque/current curve
  • Speed proportional to voltage applied
  • Requires maintenance
  • Low overloading capability
  • Low heat dissipation

Implementing Brushed DC Motor Control


How It Works


The speed of the brushed DC motor is controlled by the voltage applied to the armature, and the torque by the armature current. The flux and the torque can easily be controlled separately. This is the main principle on which all the modern control methods now rely. The controller is used to regulate the torque, speed, position or direction of the motor. Control can be implemented either in open or closed loop and the system can use feedback from optical encoder and limit switches.

Gate Driver Configuration


Unidirectional Low-Side Configuration

This drive can control a BDC motor in one direction and is often used in safety-critical applications.

Unidirectional High-Side Configuration

This lowest-cost drive technique enables most applications to simply use an output pin from a PIC® or AVR® MCU to turn on the MOSFET.

Bidirectional H-Bridge Configuration

This drive can control a BDC motor in both directions.
