Brush DC Motor Basics

Portescap's Brush DC technology originates from a design based on an ironless rotor (self-supporting coil) combined with a precious metal or carbon copper commutation system and a rare earth or Alnico magnet. It offers distinct advantages for high-performance drive and servo systems: low friction, low starting voltage, absence of iron losses, high efficiency, good thermal dissipation, linear torque-speed function. All these factors facilitate use and simplify the servo loop. For incremental motion systems where the low rotor inertia allows for exceptional acceleration, and for all battery-powered equipment where efficiency is a major concern, brush DC motors offer optimum solutions.

The Difference Between Brush Motor and 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.

A self supporting ironless DC motor from Portescap has many advantages over conventional iron core motors:

• high torque to — inertia ratio

• absence of preferred rotor positions

• very low torque and back EMF variation with armature positions

• essentially zero hysteresis and eddy current losses

• negligible electrical time constant

• almost no risk of demagnetization, thus fast acceleration

• negligible voltage drop at the brushes (with multi wire type brushes)

• lower viscous damping

• linear characteristics
