Drum motors and roller motors
General information about drum motors
The basic elements of the drum motors are: cylindrical housing, axle, stator mounted on a fixed axis; rotor attached to the housing, planetary gear. The tightly closed cage induction motor inside the drum ensures a compact design of the drum motors.
The main advantages of using drum motors instead of traditional geared motors are:
- hermetic closed motor and gear inside the drum, which eliminates the likelihood of damage due to contamination
- space-saving thanks to its compact design
- increased safety of operation - the only rotating part is the drum
- much easier installation
- usually lower costs due to the lack of the need for additional gears and additional assembly elements
- lower operating and supervision costs (drum motors maintenance-free or with oil change after 10,000 hours of operation)
- high drive transmission efficiency (up to 97%)
- easy to keep clean
- the possibility of making the conveyor entirely of stainless steel (in traditional motors, the gearmotor casing is made of either ordinary structural steel or aluminum alloys)
- greater aesthetics of the conveyor (the drive unit and transmission are not visible)
- quiet work
