Electric Motors

Electronic Surplus distributes electric AC and DC motors. Depending on the powered needed to operate your equipment, you’ll want to decide which electric motor works best for your needs. For instance, an AC motor replacement is ideal for someone who requires a powerful source of energy for an extended period of time. On the other hand, a DC motor is essential for purposes that can adjust the level of power more regularly.

If you’re unsure which electric motor for sale is right for your needs, contact us. We’d be more than happy to discuss it with you. If you already know what suits your needs, take a look at our selection of surplus motors below.
