Electric motors convert electrical energy into mechanical energy. They are used in a variety of industrial applications such as fans, pumps, compressors, cranes, machine tools and much more.

Industrial electric motors are available in a range of frame sizes, voltages, RPM, and power ratings. The most common types of electric motors are AC (alternating current) and DC (direct current) motors.

AC Motors

We offer a wide range of used AC motors for sale to meet the needs of almost any industrial application. They can be used to power conveyor systems, machine tools, elevators and much more.

AC induction motors are self-starting, meaning they don't require permanent magnets or commutator rings like their DC counterparts. The induction buy electric motors operates on the principle that when electricity passes through an insulated iron core lamina, it induces electromagnetic force, which creates torque to rotate the shaft. General purpose AC motors include designs for aeration fans, auger drives, grain stirring and metering pumps. HVAC AC motors have dynamically balanced rotors for reduced vibration and quiet operation. Pump AC motors move the impeller in a pump assembly to transfer liquid. And we even have washdown duty AC motors that can withstand frequent high-pressure washing.

DC Motors

Unlike AC motors, DC motors convert electrical energy into mechanical energy by using a stationary set of magnets (or stator) and a rotating part called an armature. The armature contains windings of insulated wire that carry current and are turned by the magnetic fields of the stator. The rotor then produces a rotating force, or torque, that causes the shaft to turn.

Brushed DC motors are used to power fans and pumps in commercial and industrial applications. They can also be found in conveyor belts and other material handling equipment. Brushed DC motors produce a constant speed range with high starting torque, making them ideal for heavy load systems that would overload an AC system. Brushed DC washdown motors are designed to withstand wet and high humidity environments. They come in several finishes including stainless steel, painted, and paintless. These Used electric motors for sale are suitable for hazardous locations as they eliminate brushes and commutator erosion, reduce noise, and create less electromagnetic interference (EMI). Brushed DC gearmotors are also available for applications that require low speeds.

Hydraulic Motors

A hydraulic motor is a mechanical actuator that converts hydraulic pressure and flow into torque and angular displacement. They are the rotary counterpart of the hydraulic cylinder as linear actuators, and are used in a wide variety of applications including but not limited to hoists, winches, tractors, cranes, conveyors, petrochemical equipment and shipbuilding machinery.

Hydraulic motors come in a number of radically different types and are designed to run at differing levels of power and speed. For example, gear motors utilise interlocking gears to convey fluid from the inlet opening to the outlet, vane motors have thin vanes protruding from a rotor to create compartments that carry fluid from the inlet to the output. Orbital motors are a type of gear-inside-a-gear hydraulic motor that generates high torques and requires minimal maintenance. Buying used hydraulic motors from JM Industrial can help you achieve your industrial goals at an affordable price. Plus, purchasing remanufactured or rebuilt motors can reduce your energy costs and carbon footprint.
