Motors and Generators

Interpoles in a generator are the same as the pole _________ with respect to the direction of rotation.

• ahead of it

• behind it

To reverse the direction of a motor, a shaded pole may

• have reverse polarity voltage applied

• be moved in special slots

Which motor has the characteristic of high torque?

• shunt

• compound

• series

• separately excited

What type of compound motor is this?

• Long Shunt

• Short Shunt

What does this double-pole-double-throw switch do?

• Turns the motor on

• Changes the armature current direction

• Changes the field current direction

What type of 3 phase winding configuration is good for balanced loads?

• star/wye

• delta

What kind of 3 phase winding configuration is good for long distance?

• star/wye

• delta

By what factor is voltage stepped up in a 3 phase star winding if you take the output across 2 phases?

• 1.414

• 0.707

• 0.632

• 1.730

In resistance start motors, the currents are out of phase by approx

• 45 degrees

• 90 degrees

• 30 degrees

If the output of this brushless generator goes down, how does the GCU compensate?

• reduces the current to the exciter output

• increases the current tot the exciter output
