Universal+Motor

Universal Motors. Universal motors have only recently been discovered by scientists. They are the super engines of the universe that cause all the galaxies to rotate around a single point.

Actualy they are just a relativly simple motor design that is used in many house hold appliances.

They are made up of field winding, an armature, followed by second feild winding, all three are wired in series.

When power is applied to the circuit, the windings energise along with the armature which create opposing magnetic feilds. These fields cause the armature to repel its self from the field windings creating the motors rotation. These motors can be supplied with either AC or DC voltage.

To reverse the universal motor, the connections at the armature must be swapped, the same can be done with the windings but if the armature and the windings are swapped then the motor will just rotate in the original direction.

Universal motors are used in: vacume cleaners, power drills, fans, just about anying with a motor in it.
