The project we have been working on is in the field of high-efficiency synchronous motors. The goal of the project was to improve the efficiency of the driveline of the GA+ compressor range. These compressors currently use an induction motor because they are connected directly to the electricity grid. The rotor cage of the induction motor allows the motor to start without the use of (power) electronics and the related losses.
To improve the efficiency of the GA+ compressor range, the client wanted to investigate the possibility of installing a more efficient, directly on-line, electric motor.
