This paper presents rib design in the rotor of IPMSM to increase maximum power in the field weakening region without variation of PM usage, conductor and size. Rib design is critical issue in the design of IPMSM due to leakage flux of permanent magnet and dominated by mechanical strength, therefore structural analysis should be conducted and minimum thickness should be selected. Rib design also affects...
This paper investigates the change of maximum power of an Interior Permanent Magnet Synchronous Motor (IPMSM) according to the rotor rib without the alteration of design factors related to the motor. As increasing the thickness of a rotor rib, it relieves stress concentration when the rotor rotates at high speed. However, the amount of leakage flux which comes from the PM makes the performance reduction...
Hydraulic system of commercial vehicle is switched electromechanical system for development of next generation vehicle recently. For example electric steering system and electric break system. This paper proposes the structural of magnetic suspension for next generation vehicle and deals with optimization of geometry of magnetic suspension. Two main characteristics are required in design of magnetic...
