Description:
Commercial motors are machines used in industrial or commercial facilities for converting energy from electrical to mechanical form. The commercial motors are driven by alternating current (AC). A closer look at the motors reveals they are designed with two main parts; an inside rotor (connected to the main output shaft) and an outside stator (featuring coils of copper wires). When current passes through the stator’s coils, it generates a strong magnetic field. The rotor also generates a rotating magnetic field. In most cases, the magnetic field in the rotor is produced using
permanent magnets. It can also be generated using electrical windings or reluctance saliency. The commercial motors can be broken into synchronous and induction motors. The induction commercial motors use variation in the speed of the magnetic fields of the stator and that of the rotor (slip induction). In the case of synchronous motors, the system uses a permanent magnet as opposed to slip-induction. The main advantage of commercial motors is that they are brushless. This reduces the problem of sparking. Besides, they generate higher torque levels compared to
AC motors.
