“…Design restrictions and specifications: Table 1 shows the parameters of the new outer rotor PMFSM using segmental rotor bonded by non-ferromagnetic material. While the concept of FSM with toothed rotor has been over half a century ago with single phase and used for airborne application, three phase with 12S-10P configuration was proposed (Ahmad et al, 2014). As interest grew in FSMs, 12S-14P outer rotor HEFSM was proposed (Chao et al, 1996).…”

Electric scooter is a brand of motorcycle using electric motors powered by electricity that is stored in a rechargeable battery. It does not have combustion engine and does not also use fossil fuel for propulsion. The electric motors installed in them improve their performances in terms of energy saving, less heat loss and quick torque response. As a result, they are solution for eliminating high cost of fossil fuel and environmental pollution that contributes to global warming. At the present time, electric motors in electric scooters is a surface mounted Permanent Magnet (PM) motor type 11" Radial Hub and is not suitable for a distance travel up to 100 km due to location of PMs on the rotating rotor. This study proposes a permanent magnet flux switching motor using segmental rotor in outer rotor configuration with the benefit of direct fabrication to sprocket and robust rotor to contain high speed. The geometric design of this motor is introduced using the parameters of eclimo electric scooter. About 2Dimensional Finite Element Analysis (2D-FEA), JMAG Software released by Japan Research Institute Version 14 is used to investigate four machine performances in terms of flux distribution, cogging torque, induced back-EMF, torque and speed versus power characteristics. Preliminary results showed that 12 slots-14 poles has high torque and high power sustainability for long distance travel.

In the past few decades, the stator permanent magnet (PM) machines have attracted much research attention because of their reliable rotor structure, high power density, wide speed range, and strong fault-tolerant ability. Among the recently proposed stator PM machine topologies, the stator slot-opening PM (SS-PM) machines are becoming increasingly popular because of their higher stator space utilization and robust rotor structure. According to the SS-PM magnetization direction, the SS-PM machines can be classified into three categories, namely, the tangentially magnetized stator slot-opening PM (TMSS-PM) machines, the radially magnetized stator slot-opening PM (RMSS-PM) machines, and the compound magnetized stator slot-opening PM (CMSS-PM) machines. The associated working principle and electromagnetic performance of different SS-PM machines can be diverse. Therefore, this paper gives an overview of SS-PM machines in terms of machine design, working principle, and machine performance. A qualitative performance evaluation and comparative study of SS-PM machines are presented, and the future challenges and potential opportunities in the SS-PM machine design are discussed.

This paper presents an operating principle of a new proposed outer-rotor hybrid excitation flux switching generator. In this Generator a combination of a permanent magnet (PM) and field excitation coil (FEC) are used as the main flux sources. Additional FEC can be used to control the flux so that constant voltage can be produced at various wind conditions. Moreover, twelve coil test analysis, Three Phase coil test flux excited by PM only, Back-EMF at various speed and stack-length conditions, magnetic flux strengthening at various current densities and flux distributions are investigated by using JMAG software. The result shows that the generated voltage is directly proportional with the change of speed and stack-length. Also parametric optimization was conducted using deterministic optimization method (DOM) and the improved design indicated a higher output voltage.
