BDL Drum Motor
The BDL drum motor, also referred to as a motorized pulley, is an advanced
and highly efficient conveyor drive system where the motor, transmission
and bearings are totaly enclosed within the drum shell. Power from the
motor is transmitted through the gearbox which is coupled to a geared
rim fixed to the drum end housing.
In the first picture to the right, you can see
a fully assembled BDL drum motor, the blue unit attached to the end of
the shaft is the terminal box for connecting power to the electric motor,
it does not contain any moving parts. The bright steel cylinder is actualy
the drum shell that houses all of the drive components which are safely
sealed inside the shell and are fully protected against agressive external
conditions that could easily cause a conventional drive to fail.
Looking at the next picture, you can see a cross-section of a typical
BDL drum motor, clearly displaying the inner workings of the drum motor
The cost-effective alternative to conventional
The BDL drum motor is priced very competitively with other drive systems
especially when considering itīs unique advantages to both the system
manufacturer and end user. Furthermore, the BDL drive is more efficient.
For example, a conventional drive system can normally transfer between
55% and 85% of its motor power to the belt. However, the BDL drive can
transfer up to 97% of itīs power to the belt and at the same time
reduce energy costs by 30% or more. This means in many cases a lower
power BDL motor can be specified against a conventional drive system.
There is little doubt that the BDL drive will
reduce energy and maintenance costs, increase productivity and quickly
pay back your initial investment cost
