<p class="p__0">For this factor, induction motors are sometimes described as "asynchronous motors". An induction motor can be used as an induction generator, or it can be unrolled to form a direct induction motor which can straight generate linear motion. A Reliable Source producing mode for induction motors is made complex by the requirement to delight the rotor, which begins with only recurring magnetization.</p>

<p class="p__1">Therefore, it is essential to either snap the motor and link it for a short time to a live grid or to include capacitors charged at first by residual magnetism and supplying the required reactive power throughout operation. Similar is the operation of the induction motor in parallel with a concurrent motor serving as a power element compensator.</p>
<br>
<p class="p__2">Then active energy is being offered to the grid. Another downside of induction motor generator is that it consumes a considerable magnetizing existing I0 = (20-35)%. Concurrent speed [edit] An AC motor's simultaneous speed, f s displaystyle f _ s, is the rotation rate of the stator's magnetic 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 synchronous speed of the machine.</p>
<br>
<p class="p__3">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) synchronous speed. The number of magnetic poles, p displaystyle p, is equivalent to the variety of coil groups per phase.</p>

<p class="p__4">The coils might cover numerous slots in the stator core, making it laborious to count them. For a 3-phase motor, if you count an overall of 12 coil groups, it has 4 magnetic poles. For a 12-pole 3-phase device, there will be 36 coils. The number of magnetic poles in the rotor is equivalent to the variety of magnetic poles in the stator.</p>
