31. Rotating magnetic fields are also used in induction motors . 32. The synchronous motor and induction motor are the most widely used types of AC motor. 33. Linear induction motors have been experimented with before, such as Westinghouse's Electropult system in 1945. 34. The proposed drive system used a linear induction motor . 35. Drive for the alternator is normally provided by a standard induction motor for convention and simplicity. 36. He found that this could be done with a coil spring attached to an induction motor . 37. Rotating magnetic fields are often utilized for electromechanical applications such as induction motors and electric generators. 38. Induction motors may be further divided into Squirrel Cage Induction Motors and Wound Rotor Induction Motors.39. The induction motor 's big drawback is its single-minded inability to turn at more than one speed. 40. Induction motors may be further divided into Squirrel Cage Induction Motors and Wound Rotor Induction Motors.
