This paper presents the design and analysis of a new double-stator permanent brushless (DSPMBL) motor for hybrid electric vehicles. The corresponding output power equation is analytically derived. The initial calculation of motor dimensions and parameters, including the core diameter, stack length, permanent magnet size and winding connection modes, are also discussed. A DSPMBL motor is designed....
The doubly-salient permanent magnet (DSPM) motor employing straight rotor and concentrated windings is conventionally operated by means of current chopping control in constant-torque region and angle-position control in constant-power region due to the trapezoidal back-EMF waveform. However, the rotor-skewing method can be used to improve back-EMF and inductances waveforms to be sinusoidal significantly...
Integrated electro-hydrostatic actuation system has the advantages of both small size and high power density. Dual-redundancy permanent magnet brushless DC motor (BLDCM) as the actuation component in electro-hydrostatic actuator (EHA) improves system reliability. But unequal electromagnetic torque in different redundant motor is a severe problem. It may impact the performance of the motor, even damage...
Permanent magnet brushless motor (PMBM) is widely used in driving system of electric vehicle because of its high power density, wide speed regulating range and high efficiency. 120deg square current for PMBM is simple in control method, but complex in simulation. A kind of simple and useful simulation module for PMBM is the key point for analyzing the torque ripple and upgrading its performance. This...
