* What are the poles of an electric motor?

 The poles of an electric motor are nothing more than the positive pole or the negative pole of the magnet (similar to that of a magnet). The minimum number of poles of an electric motor is two, one negative and the other positive. The winding and construction of an electric motor with 2, 4, or 6 poles is carried out to vary the speed of the motor. The frequency of the alternating current at 50 Hertz defines a change of direction of 50 cycles or times per second. Each cycle or change of frequency creates two magnetic fields for each pole. Transforming into a mathematical formula, we will have: 2 (magnetic field) x 50 (frequency) x 60 (transformation of frequency from seconds to minutes) Since the frequency varies depending on the various nations or countries, simplifying the mathematical formula, we will have: 120 x Hz The calculation of the motor speed depends on the rotation speed of the magnetic field and the frequency of the current, which is usually 50Hz in Europe, related to the number of poles that will result.

In conclusion, we can say that the more poles we have, the lower the number of revolutions will be. For example, a two-pole motor in Europe will have the following number of revolutions:

Number of revolutions = (120x50) = 6,000/2 = 3,000 revolutions/min
