Linear Motors - Configurations
A linear motor is effectively an AC induction motor that has been cut open and unwrapped. The “stator” is laid out in the form of a track of flat coils made from aluminum, copper and is known as the “primary” of a linear motor. The “rotor” takes the form of a moving platform known as the “secondary.” When the current is switched on, the secondary glides past the primary supported and propelled by a magnetic field.
Linear motors have a number of advantages over ordinary motors. Most obviously, there are no moving parts to go wrong. As the platform rides above the track on a cushion of air, there is no loss of energy to friction or vibration (but because the air-gap is greater in a linear motor, more power is required and the efficiency is lower). The lack of an intermediate gearbox to convert rotational motion into straight-line motion saves energy. Finally, as both acceleration and braking are achieved through electromagnetism, linear motors are much quieter than ordinary motors.
