Have you ever been faced with the situation where the drive speed cannot be changed, because an explosion-proof motor is used and installation of a frequency inverter in the electrical control room is too complex?
Here is the solution you have been waiting for: A motor with an integral frequency inverter! 

This combination offers the following advantages:

- Variable speed drive system for use in Zone1 with explosive
atmospheres
- Spatial integration of flameproof enclosed motors (CD series) in a
standard version with specially adapted frequency inverters derived
from mass produced standard models.
- Resonance effects in the drive incomers are avoided by spatial
integration, as only one sinusoidal supply connection is available. This
means that filtering which is required for installation of an external
inverter is not required.
- This drive fulfills the highest demands in the area of control engineering,
with overload, smooth running, etc., as a result of the vector control
technology applied.
- The integrated PID controller simplifies the closed-loop process control.
- The Bus technology which is available allows optimum adaption to suit
the work process.
- The frequency inverter module can be retrofitted for all PTC thermistor
motors of the CD series, from frame size 80 – 112.
- The fixing dimensions are standardized. It is therefore possible to
exchange the motors (for example EEx e) with this compact drive in
many applications.
- The payback on investment is achieved by the savings in energy costs.
- Mechanical control with throttle valve controls or bypasses can be easily
replaced. The efficieny of your installation improves significantly.
