ENERGY SAVING HIGH EFFICIENT FANS AND BLOWERS DRIVEN BY PERMANENT MAGNET SYNCHRONOUS MACHINE
KOMUNALNA ENERGETIKA / POWER ENGINERING, 5
This paper deals with the energy saving high efficient fans and blowers driven by permanent magnet synchronous machine (PMSM). In order to improve the efficiency of fans and blower, the losses due to the non-optimal operation should be minimized. A proper control of the PMSM can help to reach this goal. The fans an blower often operate under operating conditions where operation without position sensor is desired. In such cases the rotor position required in the PMSM control can be determined using appropriate models and measured currents and voltages, which leads to the sensorless control realizations. Successful implementation of the sensorless control requires a very good knowledge of PMSM parameters. Some of the methods appropriate for their determination are discussed in this paper.
