Electric Motor And Generator Teaching Systems

Students will construct various different motor designs using the motor model kit. Using a bar magnet on the model turns it into a dc motor with a direction of rotation dependent on the direction of the current. If an electromagnet is used for the stator field, as seen here, the direction of rotation does not depend on the current direction. The motor can run on dc or ac.

A motor that raises a load, i.e. converts electrical energy into mechanical energy, is a familiar everyday sight. The special feature of this set-up is that it can be used to generate electrical energy again directly from the descending weight. That electrical energy illuminates a small lamp.
