An electric motor mechanic or technician works to identify issues and repair electric motors used in a variety of equipment. As an electric motor mechanic, your duties may also include motor testing and reassembly following repair or component replacement. Your responsibilities mainly involve performing diagnostic tests and preventive maintenance. You may work to dismantle electric engines to inspect the rotating equipment that the motors use to generate power. Since electric motors rely on motor winding currents and magnetic fields, you may use your skills to work on different types of AC/DC motors, or you might specialize in one area, such as electric car motors.
