Synchronous Speed. In the steady state, the rotor speed and grid frequency has a constant relationship between n=ns=60f/p, ns known as the synchronous speed. All steel material reduction gear and ball bearings, after 45 degree Celsius heat treatment, wear resistance, good meshing performance, noise is low, and the motor high torque and runs smooth. Easy Installation. This motor has simple construction and compact size, easy to install and use. It can replace your old or broken one. Wide Application. Synchronous gear motor is widely applied to double power switch, electric advertisement, electric screen machine, over molding machine, counting machine and barbecue equipment. Shell made of metal material, pure copper coil, 2200GS magnet tile, small volume but large torque, can be rotated counterclockwise or clockwise by adjusting the wiring method., Weight: 1.99297884848 pounds, Manufacturer: Kueohse
