This lesson covers the detailed examination of the Interior Permanent Magnet Synchronous (IPMS) motor, focusing on the total torque produced by the motor. It explains the concept of reluctance torque and magnetic torque, and how they contribute to the total torque. The lesson also introduces the concept of phase advance angle, which is used to maximize the total torque. It further explains how the optimum angle for maximum torque changes with the current. The lesson concludes with the Maximum Torque Per Ampere (MTPA) algorithm, which is used to get the maximum torque for a given current by adjusting the angle.

- The total torque in an IPMS motor is the sum of the magnetic torque and the reluctance torque.
- The phase advance angle is used to maximize the total torque. This angle changes with the current.
- The Maximum Torque Per Ampere (MTPA) algorithm is used to get the maximum torque for a given current by adjusting the angle.
- The reluctance offered by a magnet is almost the same as the reluctance offered by air, which is why the reluctance is lower and the inductance is higher in the q axis where there are no magnets.
