The Design for High-Power Maglev Blower Controller

Abstract:

The maglev blower used in sewage treatment, which power is 115kW, speed up to 20000rpm, for plain bearing blower speed 6-8 times, volume is only 1/4 of the plain bearing and the noise is less than 80dB. The controller uses a DSP and FPGA dual-core controller to complete. DSP process the rotor suspension signal with digital bandstop filter program and improved PID program, FPGA complete the current signal amplification.Two chip via custom protocol to complete the data transfer. It is successful application of the controller that used in the magnetic bearing blower.
