PRODUCT DESCRIPTION
Product description
The Drum Motor is a completely enclosed electrical
drive roller, with the gear box, electric motor
and bearings located inside the drive drum. This
construction results in a Drum Motor with a very
compact design, and all the internal components
are protected against external factors. The Drum
Motor can be used in many different environments
including exposure to ne dust as well as to water
jets and water spray and is resistant to most
aggressive elements and environmental conditions.
The Drum Motor transfers the required power to
a conveyor belt, converting the drum torque into
traction force. The available internal protection
rating of IP66 or IP69 and the optional stainless-
steel design means that the drum motor is also
suitable for use in the food processing sector. An
idler pulley is a drum without an electric motor,
used to tighten the belt and create traction on the
drive drum.
Integrated thermal protection: All drum motors
are supplied with a built-in thermal protector.
Protection consists of heat-sensitive, bi-metallic
switches built into each motor phase winding.
The switches are designed to open if the motor
temperature rises to an excessively high level.
These switches must be connected to a control
circuit (in series with a magnetic coil/relay device
and contactor) that is closed by default. A motor
control circuit will cut motor power if the thermal
switch opens. Thermal switches will automatically
close as the motor cools. Cooling times vary with
pulley model, power, and size.
