“…Machines of this type include claw-pole [2][4], transverse flux [3][4], universal motors [5][6] and dc motors [7]. Attempts to replace conventional laminated permanent magnet machines by an SMC equivalent are far less researched with only two significant references having been identified [9][10], [11].…”

For years, design of conventional permanent magnet motors has been limited mainly to the variation of the stator winding function and little research has been made on stator pole modification as an alternative for motor design. Soft magnetic composites (SMCs) have opened up new possibilities for the 3-D pole shape design of both DC and AC machines owing to their isotropic properties, while having low conductivity. Here, a PM motor with trapezoidal shaped poles is presented and simulated. A modified trapezoidal-shaped poles is also proposed as further work, to reduce the torque pulsation. The latter theoretically exhibits zero torque pulsations. Some FEA results are also presented.

SMC (soft magnetic composite) materials and SMC electrical machines have undergone significant development in the past decade. For the molding of the SMC core, if a high productivity low pressure press is used, the manufacturing cost can be dramatically reduced. However, the magnetic properties of the SMC core and the machine performance are highly dependant on the mass density of the core. This paper presents the development of a claw pole permanent magnet motor with a low mass density SMC stator core molded at low pressure which can replace the existing single phase induction motor in a dish washer pump. The developed SMC motor has been prototyped and tested. Both the parameter computation and performance prediction are validated by the experimental results. These show that the low mass density SMC core is suitable for low cost mass production of SMC electrical machines.Index Terms-Claw pole motor; Low pressure molding; Magnetic field finite element analysis; Molded core; Phase variable model; Permanent magnet motor; Soft magnetic composite (SMC).

“…The load voltage allows improvements over the lamination core with the for motors also is recommended to be 42V because of respects of design freedom, low manufacturing cost, simple several benefits due to the higher voltage. The cooling fan manufacturing processes, and low eddy current losses [3], motor is one of main power consumed electric loads at the [4], [5]. Since the particles ofthe powder are insulated by the present vehicle.…”

This paper has objective to develop a 42V cooling fan system adopting a 42V BLDC fan motor with metal powdered core for hybrid electric vehicle. So, the influence on a motor design by metal powder is described and the powder is applied as a direct replacement of lamination core. The motor also has been redesigned to take an advantage of the powdered core for improving their performance on the same volume. For the design, the dynamic analysis considering the local magnetic saturation of the stator and the driving pattern by PWM driving circuit is performed based on the coupled finite element analysis with rotor dynamic equations. Also, developed motor and drive circuit is applied to the cooling fan system and compared with simulation results. From the analysis results, it must be noted that the developed type has great advantage over the conventional type toward trend of higher torque per a volume and higher efficiency.
