Everything about Large Induction Motors - Baldor.com

For this factor, induction motors are sometimes referred to as "asynchronous motors". An induction motor can be utilized as an induction generator, or it can be unrolled to form a direct induction motor which can straight produce linear movement. The generating mode for induction motors is made complex by the need to delight the rotor, which starts with just recurring magnetization.

For that reason, it is needed to either snap the motor and connect it for a short time to a live grid or to include capacitors charged at first by residual magnetism and supplying the needed reactive power during operation. Comparable is the operation of the induction motor in parallel with a synchronous motor serving as a power element compensator.

Then active energy is being offered to the grid. Another downside of induction motor generator is that it consumes a significant magnetizing present I0 = (20-35)%. Simultaneous speed [modify] An Air Conditioning motor's simultaneous speed, f s \ displaystyle f _ s, is the rotation rate of the stator's electromagnetic field, f s = 2 f p \ displaystyle f _ s = 2f \ over p, where f \ displaystyle f is the frequency of the power supply, p \ displaystyle p is the variety of magnetic poles, and f s \ displaystyle f _ s is the concurrent speed of the device.

For example, for a four-pole, three-phase motor, p \ displaystyle p = 4 and n s = 120 f 4 \ displaystyle n _ s = 120f \ over 4 = 1,500 RPM (for f \ displaystyle f = 50 Hz) and 1,800 RPM (for f \ displaystyle f = 60 Hz) simultaneous speed. The number of magnetic poles, p \ displaystyle p, is equal to the number of coil groups per stage.

Getting The Types of Induction Motor - Working, Advantages & Their To Work

The coils may span a number of slots in the stator core, making it tedious to count them. For a 3-phase motor, if you count a total of 12 coil groups, it has 4 magnetic poles. For a 12-pole 3-phase machine, there will be 36 coils. AC Induction Motors of magnetic poles in the rotor is equivalent to the variety of magnetic poles in the stator.
