This paper deals with a new configuration of gearless wheel mounted drives of trams. It introduces profitable properties of interior permanent magnet synchronous motor (IPMSM) for the drive and designs its new control strategy. The proposed control is based on a field oriented control linked to a rotor flux and optimally utilizes the reluctance component of torque in order to achieve maximum motor...
An optimal design and control technology of a wheel motor is proposed for small electric passenger cars. The axial-flux sandwich-type disc motor is designed with a rotor embedded with neodymium-iron-boron (NdFeB) magnets and two plates of stators, and is directly mounted inside the wheel without mechanical transmission and differential gears. Sensitivity analyses are performed to choose critical design...
