Used and Surplus Motors

JM industrial buys and sells used and unused electric motors from leading manufacturers in various specifications. 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. 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. JM Industrial stocks various types of used motors and drives for sale. If you have any questions, please contact us.

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:

  • The motor possesses a simple design, and can be easily built.
  • It requires low power for start-up, thus is more economical than its DC counterpart.
  • It is sturdy and has a long lifespan among the two.
  • An AC motor requires less maintenance than the DC motor.
  • The speed of these motors remain constant, so they are particularly suited for applications where continuous movements and fewer gear changes are required. This type of motor is suited for conveyors, pumps, and fans.
  • Often AC motors are integrated into variable speed systems where high accuracy is not required.
  • If equipped with speed control functions, these motors may be expensive among the two.

A DC motor is designed for industrial environments and they offer several advantages. The following are a few of them:

  • The motor is fast and ensures accuracy in terms of speed.
  • The speed of the motor can be easily controlled by varying the voltage.
  • They enable easy starting, acceleration, stopping, and reversing.
  • They are easy to install in any application.
  • These motors are suited for high power applications, too.

Owing to these advantages, these motors are widely used in dynamic applications demanding accuracy such as machine tools, elevators, robots, and so on.

Applications of Used and Surplus Electric Motors

We regularly deliver used and surplus electric motors for use in Industrial fans, Blowers, Pumps, Machine tools, Power tools, Turbines, Compressors, Alternators, Rolling mills, Paper mills, Movers and more.

Benefits of Choosing Used and Surplus Electric Motors

At JM Industrial, we take pride in our collection of electric motors for sale. These motors have been widely chosen for several distinct advantages that they offer. The following are a few advantages offered by them:

  • Cost Reduction: We stock used and surplus industrial electric motors from industry leading brands. These motors are made available in lower prices than their original ones. This makes it possible for businesses to take advantage of these motors without spending a huge amount of them.
  • Rebuilt Motors: Used motors doesn’t always mean ones with torn or worn parts. At JM Industrial we rebuild motors before offering them for sale. This makes it easier for users to achieve their industrial goals without overspending or worrying on the condition of these motors.
  • Environmentally friendly: As known, the manufacturing of mechanical devices is energy-intensive. So, producing new ones requires lots of energy, which in a way increases your carbon footprint. By buying industrial electric motors for sale at JM Industrial, you are not only reducing your carbon footprint but also making an economically and environmentally wise decision.
  • Faster Turnaround: Used or Surplus electric motor can be made available in the shortest turnaround times as compared to new ones.
