Linear Motor

Description

The Linear Motor consists of a moveable vehicle and a stationary rail. The moveable vehicle, which is mounted on four bearing rollers, contains what is usually called the stator of a conventional induction motor. The stationary rail is referred to as the rotor in a conventional induction motor. At both ends of the stationary rail, a cushioned shock absorber and a lever mechanically coupled to a DPDT switch (mounted under the stationary rail) allow the direction of motion of the moveable vehicle to be changed. This is done by reversing the phase sequence of the voltages applied to the motor windings, allowing the moveable vehicle to go back and forth over the rail continuously when power is applied to the motor.

The open construction of the moveable vehicle enables students to observe the laminated iron core and windings which form the linear motor. Each winding is independently terminated with 4 mm safety banana jacks mounted on the moveable vehicle frame to allow connection in either delta or wye (star) configuration. Two thumb screws on the moveable vehicle provide adjustment of the air gap between the pole faces and the stationary rail surface.
