Equipment
Introduction
The PASCO SE-8658A Permanent Magnet Motor
operates on AC or DC current, and it can be used to
generate alternating or direct current.
Students can not only explore properties of AC and DC
generators with this apparatus, they can also discover
key concepts and relationships concerning motors and
electric current, using the Permanent Magnet Motor in
conjunction with an AC or DC power supply and
sensors for voltage, current, and rotational speed.
The Permanent Magnet Motor includes
- armature with split ring commutator at one end
and a dual slip-ring commutator at the other
- field magnet, shaft and brush assembly
- maintenance items
- manual
- ceramic magnet

Safety precautions
- Always wear safety goggles when in a room where the Permanent Magnet Motor is being used.
- Keep fingers and other objects away from the spinning armature.
- Choose power sources that limit current to not more than one ampere (1.0 A). The motor may overheat if
this current is exceeded or if power is applied continuously, especially if the armature is not rotating. The
motor is intended only for intermittent operation.
- Disconnect any power source whenever the motor is to be left unattended.
