A brushless DC motor consists of permanent magnets that create a static magnetic field and electromagnets that when energized provide motion The magnets attach to a shaft to form a rotor with an even number of magnetic poles One or more electromagnets are wound on a laminated steel stator to form the motor phases Typically brushless DC motors have four six or eight magnetic poles with three winding phases With multiple motor phases there is always one of the phases that can be energized to provide rotational torque regardless of the rotor position with respect to the stator Energizing the phases in the proper sequence and polarity provides constant unidirectional torque Transistors have replaced brushes to accomplish phase switching Sensors determine the rotor position and turn on the correct motor phase Phases and Power Switches Motor Torque Motor Speed The most common arrangement of phases and power switches is the three phase Y connected windings with six power switches Each phase consists of two windings in series spaced 120 electrical degrees apart Each phase can be energized in either direction by turning on two of the six power devices This arrangement of switches and motor windings is identical to an AC motor drive The number of electrical cycles per mechanical revolution is equal to the number of rotor poles divided by two To control motor torque it is necessary to control the current through the motor windin
