Constant power speed range
WebA 4.3 kW, 8 pole interior permanent magnet synchronous machine (IPMSM) has a PM flux linkage (.m) = 0.65 Wb T, d-axis inductance (La) = 35 mH, q-axis inductance (La) = 63 mH, constant power speed range of 3, and is delivering maximum torque at current angle (y) of 35 degrees and 15.55 A peak/phase current. Webconstant power speed range (CPSR) is required, since the pull-out torque limit [4] can be shifted at theoretically infinite speed with a proper motor design [5]. To achieve the willed CPSR the correct matching of permanent magnet (PM) flux and rotor magnetic saliency must be found [5]. In general,
