See additional motor control applications here in battery powered applications and home and 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)
