In order to improve the efficiency, interior permanent magnet synchronous motors (IPMSMs) or the synchronous reluctance motors (SynRMs) need to be calibrated to obtain the maximum torque per ampere (MTPA) and flux-weakening (FW) curves. In industrial application, there are different types of IPMSMs and SynRMs. It is expensive and time-consuming to build test benches to calibrate each motor. In this letter, a physics-informed network is proposed to obtain the MTPA and FW operating curves. Only data from accelerating experiment, when motor operates without load, are adopted. The test bench is unnecessary. Experimental results show the validity of proposed method.
