Electrical motors enable the conversion of electrical energy to mechanical energy, and operates on the principal of electromagnetism. They are used in a wide range of applications including fans, power tools, appliances, blowers, pumps, machine tools, ships, rolling mills, paper mills, movers, electric vehicles, and more. At J&M Industrial, we carry the largest inventory of unused and used electric motors available in various frame sizes, horsepower, voltage, RPM, capacity, features and functionality. All of these motors and spare parts are sourced from top manufacturers such as Dayton, Reliance, General Electric, Baldor Electric Co. and more.
How Industrial Electric Motor Works?
Induction motor is the most common type of industrial motor used in the world. It is made of two main parts – a stator and a rotor. These parts are named on the basis of their rotation. For instance, the stator is the stationary part and the rotor is the rotating part. The stator features a three coil winding and a three-phase power input is given to it. The winding moves through the stator slots, which is made using thin and permeable steel laminations. When the electric current passes through the winding a rotating magnetic field is produced, which makes the rotor to turn. The magnet rotates at a certain speed, and this speed is known as the synchronous speed. According to the Faraday’s Law, an EMF is induced in the loop due to the varying magnetic field. This EMF produces current in the loop. The Lorentz Force Law states that electromagnetic force is produced in the loop, which makes it rotate. In short, electricity is induced in this rotor owing to electromagnetic induction rather than direct connection. The insulated iron core lamina is found inside the rotor, and it induces electromagnetic induction. Small iron cores are chosen for the purpose, because they help minimize the Eddy current losses. Unlike other motors, the induction motor has one major advantage – it is self-starting. They do not require permanent magnets, commutator rings, or brushes like other machine counterparts. The speed of induction motors can be easily controlled by managing the input power frequency. In these motors, the speed of RMF is proportional to the power applied, because the rotor tries to match up the RMF. The speed of these motors is usually controlled using variable frequency drives.
How to Choose Between an AC Motor and a DC Motor?
A motor is termed as an AC motor or a DC motor based on the power source— the alternating current and direct current sources. Motor vehicles, batteries, and rectifiers are a few examples of DC sources. On the other hand, inverters, power grid, and electrical generators are a few examples of AC sources.
AC motors are mainly of two types – single-phase and three-phase. These motors are commonly used in various industrial applications owing to the advantages offered by them. The following are few of them:
A DC motor is designed for industrial environments and they offer several advantages. The following are a few of them:
Owing to these advantages, these motors are widely used in dynamic applications demanding accuracy such as machine tools, elevators, robots, and so on.
