Used indoors only. Continuous duty. A motor and speed reducer in one, these gearmotors have hypoid gears for energy-efficient operation. You can use them to turn a shaft on your equipment or add a keyed shaft (sold separately). Wire for clockwise or counterclockwise rotation; instructions are included. Gearmotors meet IP54 for protection from dust and splashed water. They're inverter rated so you can use them with a motor speed control (not included) to adjust the motor speed.
