Introduction
The PASCO SE-8657 Motor Accessory transforms the
PASCO EM-8641 Variable Gap Magnet into a motor
that can operate on alternating or direct current, as well
as a generator that can produce alternating or direct
current. The Motor Accessory also transforms the
PASCO SF-8616 Coils and Cores Set into a universal
motor. Combined with an AC/DC power supply and
sensors for voltage, current, and rotational speed,
these motors allow students to discover key concepts
and relationships concerning motors and electric
current. Students can also explore properties of AC
and DC generators with this apparatus.
The Motor Accessory includes
- armature with split commutator at one end and a
dual slip-ring commutator at the other
- brush holder
- shaft
- wrench/retaining nut
- maintenance items
- manual
- ceramic magnet
Additional Equipment Required:
- Variable Gap Magnet (EM-8641) or
- Coils and Cores Set (SF-8616)

Safety precautions
- Always wear safety goggles when in a room where the Motor Accessory 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.
