Permanent magnet brushless DC motors (PMBLDC) are used in a wide range of applications thanks to their high-power density and ease of control. In particular, outer runner PMBLDC is utilized in direct drive wind turbines and small electric vehicles such as golf cars and electric bikes to mitigate the need for mechanical transmission or gearboxes. This can improve the efficiency of the whole system which results in a longer battery lifetime

Electric motors are becoming increasingly used in industrial applications. They offer a high efficiency, high power factor and a wide speed range. The spoke type motor is one of the common electric motor types presented in the market today. Spoke type motors use a compact permanent magnets structure, arranged in spokes for a better torque generation [1]. With the adequate material selection, the spoke type motors have the highest torque density architecture among the permanent magnet motor types, provided they are cost-effectively manufactured and especially effectively cooled [1].

Battery and electric motor are the main keys of any zero-gas emissions vehicle. Hence, engineers, researchers and labs are working to design and develop more reliable products that could meet any user requirements

Permanent Magnet Synchronous machines (PMSMs) are widely used in traction applications and electric vehicles, where steady-state operation, high efficiency, and torque density are needed, such as Toyota Prius, etc.

Linear actuators have many applications ranging from domestic to industrial. Their role consists of converting many forms of energy such as electrical energy, hydraulic energy etc to a mechanical linear motion.

In this paper, an FEM simulation of brushless DC motor using EMWorks2D is established. The model is created using MotorWizard inside SOLIDWORKS. Magnetic flux and Torque results are generated verus rotor angle.

A switched reluctance motor (SRM) is a rotating electric machine where both stator and rotor have salient poles (Figure 1). The stator winding comprises a set of coils, each of which is wound on one pole.
