Description

The motor consists of a two pole armature mounted between the ends of two bar magnets. The armature has a two section commutator and a pair of slip-rings on its shaft and is so constructed that the wire cannot slip off the iron core. The upper bearing and brushes for the commutator are mounted on a strong upright. Separate brushes are provided for the commutator and for slip rings and each are connected to a terminal. The magnets are held in position by thumb screws.

Description

The dynamo model is mounted on a base with a driving wheel. Output is through 4 mm sockets and a low voltage bulb is also provided as a simple output indicator.

Description

With this simple electric motor model students can investigate the relationship between voltage supplied to rotor and polarity / position of magnets. On applying 6V DC to 4mm sockets, the rotor will begin to rotate across its vertical axis.
