A method (100) for estimating a speed of an induction motor includes applying (102) a voltage to the induction motor and measuring (104) a current of the induction motor. A current fast fourier transform (FFT) of the current is then determined (106) and a slip of the induction motor ...

Inthe multiple stator winding method of speed control, the stator is provided with two separate windings which are wound for two different number of poles. One stator winding is excited at a time. For example, suppose that a motor has two stator windings for 4 and 8 poles. For 60 Hz supp...
This paper describes the electrical, mechanical and metallurgical design, construction, and testing of a novel low-cost high-speed high-efficiency induction motor to drive a new type of small centrifugal compressor in industrial cooling applications. The 28-shaft-hp 50-kr/min motor features a uniqu...

machine requires for efficient, dynamic and stable variable speed control. Modern electronic control technology is able not only to render the a.c. induction motor satisfactory for many modern drive applications but also to greatly extend its application and enable advantage to be taken of its low...
A speed sensorless induction motor (IM) drive with robust control characteristics is introduced. First, a speed observation system, which is insensitive to the variations of motor parameters, is derived based on the concept of sliding mode. Next, an integral-proportional (IP) speed controller using...
From the formula, we see that the rotor always rotates slower than the revolving magnetic field. If the rotor moved at the same speed as the field, there would be no flux cutting action and no emf induced in theconductor, causing the motor to slow down. This is whyinduction motornever ...
