[Vol.015] IPM Interior Permanent-Magnet Motor (Part 1 : The Rotor)

From this 15th seminar, we will be covering IPM motor design and this will be part 1, the rotor edition.
Up until the last seminar, we completed the design of a 10kW induction motor. We will now change only the rotor to IPM. For comparison’s sake, the stator shape of the induction motor will be used as it is for the IPM motor.
In this seminar, we will design the V-shaped rotor. I will introduce the historical changes in the rotor of permanent magnet motors and explain what each dimension is heavily dependent on.

You can also make inquiries to Prof. Miller if you have any questions.
There is a comment form at the bottom of each seminar page.
If you have any comment for “Webinar: Brush up on Motor Design!”, please!!
