WebJun 22, 2024 · Permanent Magnet Synchronous Motor (PMSM) is brushless and has very high reliability and efficiency. Due to its permanent magnet rotor, it also has a high torque with a small frame size and no rotor current. Instead of using winding for the rotor, permanent magnets are mounted to create a rotating magnetic field. WebAt 0.7 s, motor speed ramps to 2400 rpm and the load torque reduces to 150 N.m. The speed regulator performs well for both speed settings. At 1.0 s, the load torque inverts from + 150 to -150 N.m so that the machine now operates as a generator. Test 2 : This test shows the impact of the MTPA control on the motor currents.
