1.Puropose-build Design The drum motor has been specifically designed for belt conveyors
2.Totally enclosed The motor, gearbox and bearings are totally enclosed and sealed
inside a steel shell; therefore they are unlikely to fail due to harmful environmental
conditions such as water, dust, grit chemicals, grease, oil, etc.
3.Space saving design Because the drive unit and the bearings are mounted inside the
motorized pulley shell, it takes up much less room than a conventional drive. No need for
costly extras like chains, v-belts, couplings, bearings, support structure and special
guarding.
4.Safety The drum motor is probably one of the safest drives available
because the motor is completely enclosed and the external shafts are always
stationary. The only moving external parts are the motorized pulley shell and bearing housings.
5.Low purchasing and installation cost The drum motor is quite often less expensive than exposed drives
because it has fewer parts. Therefore less conveyor design and parts purchasing costs. It is
also much quicker and easier to install-certainly less than a quarter of the time taken to fit an
exposed system.
6.Low maintenance cost The end user also benefits from the drum motor, because it requires
no maintenance other than the recommended oil change every 10,000 hours and oil
seal change every 30,000 hours. In other words almost 5 years between oil changes based on
8-hour/day working week. Synthetic oil can be specified to extend the service range up to 30,000 hours.
7.Efficiency The drum motor usually has a much higher efficiency from electrical
motor to shell(pulley face) than conventional drives, because it has fewer frictional losses,
and therefore efficiencies of up to 94% can be achieved.
8.Fewer parts A drum motor consists of the motorized pulley and two fixing
brackets! Exposed drives can require up to eight or more separate components, most of which have to be purchased from different supplier or
custom manufactured.
9.Low noise Thanks to the totally sealed enclosure and high quality gears the
motorized pulley runs almost at a whisper-a very important fact in todays modern factory
environments. |
