Motor Testing

1. The burden imposed on a motor by the driven machine.
4. The space between the rotating (rotor) and stationary (stator) members in an electric motor.
6. An alternating current motor in which the primary winding on one member (usually the stator) is connected to the power source.
9. an auxiliary set of field poles carrying armature reaction in a DC motor.
11. A dual speed motor with torque values that vary with speed (as the speed changes the horsepower remains constant).
12. A device that takes electrical energy and converts it into mechanical energy to turn a shaft.

2. The portion of the magnetic structure of a DC or universal motor which rotates.
3. The number of times per minute the shaft of the motor (machine) rotates. This is a function of design and the power supply.
5. A gearhead and motor combination to reduce the speed of the motor to obtain the desired speed or torque.
7. The rotating member of an induction motor made up of stacked laminations.
8. The part of an AC induction motor's magnetic structure which does not rotate.
10. The rotating member of the motor which protrudes past the bearings for attachment to the driven apparatus.
