Because spread and display this picture, there is a case to look coarse.

The photo 1 shows an example PRM of applying for a HEV truck motor. PRM is installed between the engine and transmission, and on the outer side of the flywheel to reduce torque ripple, its outer diameter of about 400 (mm). Its shape is short axis with a large diameter in this example. The motor became 2 / 3 of the current of the induction motor in size and has been achieved the 1.4 times maximum torque,350 (Nm).
