Description

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.
