Özet

In this study, a new 46-pole brushless DC motor with three-levelled stator and rotor structure for electric vehicles which are considered to be a permanent part of our daily lives in the future has been designed and manufactured. The system consisting of three levelled brushless DC motors with 46 poles has been configured to be used in new generation highly efficient electric vehicles. The operation of designed multilevel brushless direct current motor is based on the principle of driving MOSFETs on driver circuit by evaluating data from those three Hall Effect sensors placed on the stator at a right angle as it is the same for in-wheel conventional brushless direct current motors. The performance characteristics of designed prototype have been examined via finite element methods (FEM). The design and simulation principles followed in manufacturing electrical machines have been applied respectively, and parametric analysis has been realized. It is proved that the three-levelled motor with that aforementioned structure and driving scheme is superior to conventional brushless motors having the same sizes in terms of criteria such as output torque, unit power density and etc. and the purposed model is particularly well suited for the applications like electric cars andmilitary applications where high torque is needed.
