Motor Picture

A brush DC electric motor is an internally commutated electric motor designed to be run from a direct current power source and utilizing an electric brush for contact.

Brush motors were the first commercially important application of electric power to driving mechanical energy, and DC distribution systems were used for more than 100 years to operate motors in commercial and industrial buildings. Brush DC motors can be varied in speed by changing the operating voltage or the strength of the magnetic field. Depending on the connections of the field to the power supply, the speed and torque characteristics of a brush motor can be altered to provide steady speed or speed inversely proportional to the mechanical load. Brush motors continue to be used for electrical propulsion, cranes, paper machines and steel rolling mills.

The Difference Between a Brush and a Brushless Motor

With brush motors, the stationary field (stator) is created by permanent magnets interacting with a rotating field (rotor) which contains the motor windings. Brushless motors are just the opposite - in that the stator field is the wound member and the rotating field is the permanent magnet.

In both cases, the interaction of these fields produces a torque which turns the rotor. As the rotor turns, current in the windings is switched - or commutated - to produce a continuous torque.

• The brush commutated unit typically uses brushes made of graphite that ride on metal bars [the commutator] that are connected to the rotor coils. As the rotor turns, the brushes transfer current from one set of coils to another.

• The brushless units rely on their commutation through the use of a shaft position sensor sending a signal to an external winding switching circuit.

Typical Speeds

Brush units work best continuously between 1,000 RPM and 10,000 RPM. The higher speeds are limited to a practical limit of 10,000 RPM due to the mechanics of brush to commutator interface characteristics. As the rotor speeds up, the brushes begin to float over the commutator, making poor physical and electrical contact. On the other hand, brushless motors can typically run at higher speeds – they are only limited by the mechanical integrity of the rotor, speed related losses and the stability of the bearings being used.

Noise Generation:

Audible noise in brush motors comes from bearings, brushes and rotor imbalance. In brushless designs, the noise generation from brushes is eliminated, making brushless designs quieter.
