DRUMOTEC® supplies Heavy duty drum motors in the following sizes:
0,37KW – 400KW
The electrical motor, gears and bearings are mounted inside the drum, which creates a very compact design. Oil is used for permanent lubrication of gears and bearings as well as cooling the electrical motor. Our high quality sealing system prevents oil coming out as well as dust and water coming into the drum. We use different sealings for different applications. Using the right sealing system you can avoid any risk of dust and water coming into the drum. The drum is standard crowned to secure a better belt tracking.
Flameproof drum motors EX-d
Now DRUMOTEC® EX-D motors are also available for certain applications.
DRUMOTEC® offers a strong drum motor designed to handle the heavy duty task in the BULK industry, indoor, outdoor as well as underground, whether the conveyors are in the mining industry, power plants, mobile applications, recycling industry and many others.
A DRUMOTEC® drum motor is constructed as a completely enclosed conveyor drive – dust and water tight according to IP66 or DIN EN 60529. Beyond that we offer regreasable labyrinth seals for very abrasive applications within the BULK industry.
Seals mounted on hardened stainless steel o-ring
Having seals rotate directly on a steel shaft will lead to a groove appearing in the shaft, creating a risk of oil leaking. DRUMOTEC® drum motors seals are mounted on a hardened stainless steel o-ring, which wear slowly and is quite easy to replace.
Brake and backstop
DRUMOTEC® drum motors are available with integrated electromagnetic brake, mechanical brake as well as backstop.
The motors are supplied for the standard voltages 230V, 400V at 50 Hz and can be operated, without reduction of the nominal power, with variations of the nominal voltage in accordance of VDE 0530. Motors for systems with different voltages and frequencies are available upon request.
All statements in lists are related to main frequency of 50 Hz. At different frequencies the belt speed changes according to the change in frequency. DRUMOTEC® drum motors are as standard prepared for VFD operation.
In our standard drum motors the electrical motors are three phase induction motors with special squirrel cage rotor, which give the engine the highest breakaway torque at highest operation security
Insulation of the motor windings
Windings and insulation of the DRUMOTEC® conveyor drum motors correspond to insulation-class F according to VDE 0530 (max.Temp. 155°C).
Winding thermostat (WT) or temperature probes (PTC) in order to protect the motor winding against any abnormal temperature rises are available.
A standard DRUMOTEC® drum motor is always supplied without rubber coating. On request we can supply them with rubber or ceramic coatings as far as this is possible in respect of heat disappation.
DRUMOTEC® offers tail drums with fixed shafts and internal bearings suitable for our entire range of drum motors.
