Question 1 of 6
Intermediate

How can the magnetic field around an electrical conductor be strengthened?

Question 2 of 6
Intermediate

When power is applied to the stator, an expanding magnetic field is created that cuts across the rotor conductor bars and induces current in the rotor.

Question 3 of 6
Intermediate

You can typically increase motor efficiency by 5% by using a permanent magnet synchronous motor instead of an induction motor?

Question 4 of 6
Intermediate

The slip in an induction motor is greater at no load than it is at full load?

Question 5 of 6
Intermediate

When power is applied to the stator, an expanding magnetic field is created that cuts across the rotor conductor bars and induces current in the rotor. This is the basic principle of which of the following?
