BLDC Motor Controls

Selcom Group has a deep knowledge in the development and implementation of “brushless” variable speed drives. Noteworthy are the developments in the “energy saving” applications, where the BLDC technology offers superior characteristics. We have developed sophisticated “sensorless” control techniques in order to respond to the different application requirements (refrigeration, washing, etc). These techniques offer the most suitable technical and economical solutions, even in some specific wide speed and torque ranges (hermetic compressors).

Some interesting examples are:

Wide Range Variable speed solutions
“Adaptative” speed algorithm embedded
ASIC, uPcontroller, and DSP based logic design
Mospower and IGBT power based power design
Flexible application (on board configurable) :
              Interface with standard electromechanical switch (“drop-in” solution)
              Interface with external electronics (serial line or “frequency” mode)
              Interface with Personal Computer (commands and data logging)
Highly integrated design:
On board very efficient switching power supply)
On board EMI / EMC line filter
On board in-rush current limiter
On board serial line connection (optoinsulated)
Estimator based sensorless solution
Costant Torque and Costant Power algorithm
Sealed box solutions (Water Proof and R600 gas)
