Literature Review As compared to other motors, the literature survey is divided into two sections that are Selection of the type of motor Type of change in property of the BLDC Given in the References section area series of research papers used as an initial understanding and comparison for the purpose of this project. The various papers are used to select and simulate the required motor. Motor Design As seen in the references, reference paper one and paper two give a detailed overview of the various types of PMSM and BLDC Motors. After a keen study of these papers, it can be inferred that the BLDC Motor is the best motor to be used for Electrical Vehicle Applications due to their tested efficiencies and response to signal error tests, mechanical, thermal and electrical properties tests and their total power consumption rates. The Brushless DC Motor has a series of advantages and also poses for high torque and speed values [7]. Design Manipulations On keenly studying the remaining references, [8-13] we find that there have been a various number of iterations done on the BLDC Motor with respect to the design and power electronic drive modules. Greater stress has been given to the design aspect of the motor by implementation of smaller designs, size affecting the functionality of the motor. Some of the tests done in these iterations lead to higher efficiencies but a boxed (un-ambidextrous) design. The motive of this project is to avoid the same in order to have an ambidextrous motor design with the same higher efficiency values and smooth function. E. Why BLDC? An electrical vehicle can be operated by using two different types of motors. One being the conventional Induction Motor (IM) and the other being the BLDC Motor. The IM offers high torque and minimalistic ally high speed operations for any specific rating. The BLDC motor is also capable of the same yet there is a catch. As the rating of the required machine increases, the size of the Induction Motor increases exponentially [14]. This means that when considering size constraints, the size of the BLDC motor fora particular power rating is smaller compared to the size of an Induction motor for the same power rating [15]. There are advantages and disadvantages to the same yet during the retrofitting operation, the size is a very strong parameter as the motor mounted to the body has to have a small and compact shape due to the relatively low availability of space in the chassis due to its prefixed design.
