ABSTRACT:
An electrical linear motor stator is fixedly disposed along a roadway. A car supported on at least two trucks is guided for movement along the roadway. The trucks are pivotally mounted to the car for rotation about a vertical axis. Permanent magnets for interacting with the stator have one end pivotally mounted to the vertical axis of the truck and an opposite end guided, for example, using rollers, for positive movement parallel to a vertical longitudinal central plane of the stator. In this way, the permanent magnet is mounted for transverse movement to the car to permit the car to negotiate small radius curves in the roadway while still maintaining good alignment between the permanent magnet and the stator.
