AN EXPERIMENTAL STUDY OF A HOMOPOLAR LINEAR SYNCHRONOUS MOTOR

This paper presents some experimental results obtained from a small homo-polar linear synchronous motor which has been tested on the two-metre test wheel facility at the University of Toronto. The primary of the motor has both armature and field windings while the secondary consists of alternately-placed solid iron poles on the wheel rim. A short three-pole primary has been used so that end effects are accentuated. Test results are presented over a wide range of operating speed, load angle and winding currents. These results indicate that the motor is a promising contender for urban transit propulsion.
