See additional motor control applications here in Battery Powered Applications and Home & Building.

There are three main types of brushed DC motors: series wound (uni-directional), shunt wound (bi-directional by changing connections) and permanent magnet (bi-directional by reversing current). Powering a set of windings generates a magnetic field in the rotor. The opposing magnetic fields (N-N and S-S) push away from one another creating rotation until the fields align (NS – NS).

Example Application for Brushed DC Motor Control and Drives

Key Characteristics Brushed DC Motor

  • Easy to control: torque is proportional to current – speed is proportional to voltage
  • Moderate efficiency
  • Variable speed: fewer external components required than induction or brushless DC motors
  • Maintenance necessary as brushes wear out
  • Louder than induction motors (EMI and audible)
