1. The difference between these two is the location in the motor. The rotor is connected to the mechanical load through the shaft. The synchronous induction motor, as its name implies, is a machine which is capable of running both as an induction motor and as a synchronous motor, the former being its mode of operation during the starting period, and the latter its mode of operation during normal running. 208 volts (V) is a common supply voltage for some applications in the United States, however, it is common for a manufacturer to indicate the expected current at 208 V as an alternate voltage rather than stock different products with 208 V as the primary rating. It results in smooth operation and reduces the humming noise. 23. These motors can be either an induction motor (also called an asynchronous motor) or a synchronous motor. If we draw a circuit showing each voltage source to be a coil of wire (alternator or transformer winding) and do some slight rearranging, the "Y" configuration becomes more obvious in Figure below. F. or S.F.) For the synchronous mode of operation it is necessary to supply the rotor winding with direct current. What is a Wound Rotor Motor and How Does it Work? The rotors of the three phase induction motor are further classified as: Squirrel Cage Rotor. The three basic types of three-phase motors. The speed of the rotating magnetic field is known as synchronous speed (NS). The three basic types of three-phase motors. | bartleby The interesting point about this motor is that its peak torque as an induction motor exceeds that as a synchronous motor. 2 - Full-Load Current for a 3-Phase, 460V, 10 HP Motor Such a motor provides more or less constant speed at all loads, for a given tapping on the transformer. 10.

Determine the maximum rating for a branch-circuit short-circuit ground-fault protective device allowed for an inverse time circuit breaker for a 15 HP, 460 VAC, 3-phase motor.
