A drum motor is a geared motor drive enclosed within a steel shell providing a single component driving pulley for conveyor belts. The drum motor concept was first recorded, but it was not used until the early, when it was first produced specifically for conveyor belt applications. A drum motor (or motorised pulley) is a geared motor drive enclosed within a steel shell providing a single component driving pulley for conveyor belts.
A drum motor is a one component conveyor drive where the motor, gear drive and all moving parts are enclosed inside the drum. The motor and gears operate in a sealed oil bath ensuring proper lubrication and cooling. Synthetic, mineral, food-grade, low viscosity, and high viscosity oils are all available. Under normal operating conditions with a motorized pulley running continuously at full load, synthetic oil and synthetic food grade oil should to be changed after every 50,000 hours of operation.
The driving drum is used for transmission of the pull force needed for putting the belt in motion. The driving drums are the elements of the conveyor equipment intended for transportation of cargoes, bulk materials, products and parts in different industries. The drum motor uses an asynchronous or synchronous electric motor, or hydraulic motor fixed to a stationary shaft. One end of the drum is directly coupled through the motor’s rotor pinion to an in-line helical or planetary gearbox which is fixed to the other stationary shaft.
