Used and surplus AC motors for sale. MRO Exchange carries a rotating selection of AC induction motors available for immediate purchase and fast nationwide shipping.

AC induction motors are the most widely used electric motor type in industrial manufacturing. Reliable, low maintenance, and available across a wide range of horsepower ratings and frame sizes, they power virtually every category of general industrial equipment from pumps and fans to compressors, conveyors, mixers, and machine tool auxiliaries. When an AC motor fails on production equipment the replacement decision is straightforward: match the horsepower, frame size, voltage, and enclosure type of the original and get the equipment back running.

The surplus market is a practical first stop for AC motor replacement for two reasons. First, standard AC motors are interchangeable across manufacturers when the key specifications match, which means a surplus motor from a different brand than the original is a valid replacement in most applications. Second, less common frame sizes and high-efficiency premium designs carry significant list prices through standard distribution, making surplus sourcing a meaningful cost saving even for readily available motors.

Selecting a replacement AC motor:
Horsepower rating must meet the load requirements of the driven equipment. Frame size determines the physical mounting dimensions and shaft configuration. Voltage and phase must match your facility power supply. Enclosure type, whether TEFC, ODP, or explosion-proof, must suit the installation environment. Service factor and efficiency class are secondary considerations but worth confirming for energy-sensitive applications.

Every AC motor listed on MRO Exchange ships nationwide from our facility in Illinois at prices well below new distributor cost.
