The power the electric motor is nothing more than the force that is generated by the electric motor to move the load at a given speed. The power of the electric motor has a specific way in the electric motor nameplate and this indicates the mechanical power that is available at the tip of its axis. To be determined the electrical power that is consumed by the electric motor is necessary to divide its mechanical power for their income.
The rotation is nothing more than the number of electric motor shaft turns per unit time. The rotation is usually expressed in rpm which are rpm. The electric motor of two and four poles are the most sold in the market.
The slip in turn is a description of the difference between the synchronous speed and the actual speed at the tip of the electric motor shaft. Factors such as load or even the variation of the mains voltage can influence the rotation of the electric motor.
