The basic parts of a brushed dc motor are. The resulting motor is only practical in the smallest sizes.

Brush motor diagram. The brushes may also be lifted to prolong brush life. The permanent magnets are stationary so they are called the statorthe armature rotates so it is called the rotor. In a typical dc motor there are permanent magnets on the outside and a spinning armature on the inside. Commutator type motors these schematics are of commutator brush type ac and dc motors. Ac commutator motors fig. A motor generally contains more.
Stationary motor shaft and washers armature rotor commutator and sometimes a varistor and. Universal type compensated series connected ac motor circuit diagram. The commutator and the brushes. Brushes and terminals or leads. The article how electric motors work explains how brushed motors work. Carbon brushes for electric motor repair are designed to increase brush life and surface contact to enhance performance.
Case bearing and stator magnets stator ie. The diagram below shows this layout in an exploded view of a typical dc motor in this case a small ø12mm vibration motor. Eis supplies various types of brushes and accessories such as. Starting torque is 300 to 600 of the full speed value as compared to under 200 for a pure induction motor. A brushed dc electric motor is an internally commutated electric motor designed to be run from a direct current power source. The flipping the electric field part of an electric motor is accomplished by two parts.
The armature contains an electromagnetwhen you run electricity into this electromagnet it creates a. Commutator and brushes the diagram at the right shows how the commutator and brushes work together to let current flow to the electromagnet and also to flip the direction that the electrons are flowing at just the right moment. The brush is typically made up of one or more carbon blocks and can come with one or more shunts or terminals. A carbon brush also known as a motor brush is the small part of the motor that conducts electrical current between the stationary wires stator and the rotating wires rotor of a motor or generator. These brushes are typically found in dc motors generators slip ring motors motors and grounding applications. The single phase series motor is an attempt to build a motor like a dc commutator motor.
Brushed 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.
