This paper presents an energy recuperative eddy current retarder (ERECR), which offers a solution to the energy consumption and overheating issues of the conventional eddy current retarders (ECR). The ERECR obtains three main systems, namely Eddy Current Braking (ECB) system, Regenerative Braking (RGB) system, and Electrical Control System. The RGB system, which could recover the kinetic energy from...
This paper present a new design of a Limited angle torque motor (LATM) with Dual Halbach Arrays for rotary direct drive valve (DDV), which needs high frequency response, high power to weight ratio. Reluctance model of proposed LATM is discussed. The structure parameters are optimized by particle swarm optimization (PSO) method to improve performances, especially the output torque. The optimized parameters...
A novel tubular flux-switching permanent magnet (PM) linear motor is proposed in this paper. It takes the hybrid operating principle of conventional flux switching machines and excitation of permanent magnet poles. It helps to increase the magnetic flux density in air gaps, and improve the force output. The complementary phase is employed to reduce force ripples. Modular design methodology is utilized...
This paper presents a tubular linear flux-switching permanent magnet (TLFSPM) motor. It has an inner mover which only consists of iron core, and stator which contains the magnets and armature windings. The objective of this paper is to propose the TLFSPM motor design and mathematical model. This motor has a smaller cogging force and force ripple, in addition, it overcome unbalanced magnetic circuit...
