=== Externally excited motors === [[File:Electrical Machinery 1917 - Westinghouse motor.jpg|thumb|Externally excited motor, 1917. The exciter is on the left.]] Usually made in larger sizes (larger than about 1 horsepower or 1 kilowatt) these motors require [[direct current]] (DC) to excite (magnetize) the rotor. This is most straightforwardly supplied through [[slip ring]]s. A [[Brushless DC electric motor|brushless]] AC induction and rectifier arrangement can also be used.<ref>H.E. Jordan, ''Energy-Efficient Electric Motors and Their Applications'', page 104, Springer, 1994 {{ISBN|0-306-44698-7}}</ref> The power may be supplied from a separate source or from a generator directly connected to the motor shaft.
