What Is Drum Motor (or Motorized Pulley)

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.Tongxiang is a professional conveyor pulley manufacturer.
The drum motor comprises an asynchronous or synchronous electric motor, or hydraulic motor fixed to a stationary shaft at one end of the drum and directly coupled through the motor’s rotor pinion to an in-line helical or Planetary Gearbox which is fixed to the other stationary shaft. The torque is transferred from the motor via the gearbox to the drum shell through a coupling or geared rim attached to the shell or end housing.

Because of the in-line transmission arrangement using 2 or 3 stage helical or planetary gears, up to 95% of the output power produced by the motor is typically transmitted to the drum shell. Gears can be made from high grade steel, sintered metal or polymers.
The drum motor is often used in airport check-in conveyors and security machines, food processing conveyors and weighing equipment, etc. The drum motors can be installed horizontally or vertically and used in non-conveyor belt applications.
These economical Magnetic Separation Pulleys can be used to replace your existing head pulleys to turn your material handling conveyor into a material separation conveyor. These pulleys can be provided with the same shaft as your existing conveyor has.
We are conveyor roller manufacturers.To match up to your conveyor, we offer an assortment of Taper Lock or QD hubs for any shaft diameter you need or welded in shafts to slip into the end of your conveyor.Our Magnetic Pulleys come in 4”, 6”, 8”, 10”, 12”, 15”, 18”, 24” and 30” diameters sizes and in widths from 4” up to 72” wide. We offer the pulleys in an economical stepped crowned face, machine crowned face, flat faced and an assortment of rubber vulcanized crowned covers.
According to the cooling mode, the drum motor can be divided into air-cooled drum motor, oil-cooled drum motor and oil-immersed drum motor. The drum motor comprises 3 drive modes: fixed shaft gear drive, cycloidal gear drive and planetary gear drive. And the electric motor can be installed internal or external of the motorised pulley.
TX ROLLER provide continuous protection against tramp iron contamination of both large and fine metal particles. We offer magnet sizes for every application, as small as 4″ diameter. Our magnetic pulleys are available in regular strength and a “high power” version for more extreme applications. We design and construct each magnetic pulley to withstand the harshest of environments and back each magnetic pulley with a full warranty. We welcome questions, pictures and any information about your application and will provide custom pulley sizes upon request. We carry many sizes in stock and have extremely fast turnaround times.
