TDY Drum motor

Description ：

TDY-Drum Motor  is a steel drum ( as used in a conventional pulley)  however the drum rotates around the shaft – but the shaft does not move.
The rotating drum acts much like a traction pulley so that it can grip and drive the belt

The electricity needed is sent through the shaft to controls within the pulley. Since the shaft end does not rotate, there is no need for slip rings to deliver electrical energy to the motor windings.

The internal mechanism — motor, gears, and bearings — is completely sealed and protected by the outer metal drum.


Before running, the sections inside are filled with an appropriate lubricating fluid, the fluid continuously lubricates the bearings and gears as well as, acts as a coolant to remove heat from the motor. This oil keeps the motor cool, extends service life, and reduces maintenance.


with the drive mechanism inside, a motorized pulley is more compact than a conventional drive system and so reduces space requirements a
Safety is improved as all moving parts and electrical connections are completely enclosed within the drum.

Efficient  Motorised pulley run to high efficiency with a greater than 90 % of horsepower transferred directly to the conveyor belt.

Servicing a motorized pulley is an oil change according to the manufacturer’s specifications.  – This allows for service periods to be about once every year if the machinery runs about 24 hours a day, every day for one year
These motorised pulleys have a much-reduced noise level due to moving sections being contained within the outer shell that is sealed and oil-filled.
