Abstract(E) | We have developed the high-speed permanent magnet synchronous motor (PMSM) with a maximum rotation speed of 22,000 min-1, which enables the motor to be downsized. This PMSM is applied to a welding-less coil to shorten the axial motor length and a robust rotor structure to achieve high rotor strength. Elemental tests and measurements demonstrate that (i) the rotor does not deform under high rotation speed and (ii) the torque and coil temperature of the developed PMSM reach their design values. |
