Sterowanie silnikiem synchronicznym z wewnętrznymi magnesami stałymi IPMS uwzględniające ograniczenia

In this article the limitations connected with the IPMS motor operation were presented. In the static state, the limitation on a stator current, stator flux versus rotary speed of rotor ω r and on power angle δ were considered. In possible range, MTPA (Maximum Torque per Ampere) operation was predicted. The method of motor controlling that guarantees to comply with these limitations was worked out. The operation of the IPMS driving scheme in various operation ranges with control cycle Ts = 150 žs was tested by simulation. The measurements of rotor speed and two stator currents are required for proper controlling. The initial rotor position must be known also. This position is determined by means of series of voltage pulses feeding the stator at the beginning of controlling.
