Propulsion system

Propulsion means the action or process of pushing or pulling to drive an object. The term is derived from two Latin words: pro, meaning before or forward; and pellere, meaning to drive.

A propulsion system consists of a source of mechanical power, and a propulsor (means of converting this power into propulsive force). A technological system uses an engine or motor as the power source (commonly called a powerplant), and wheels and axles, propellers, or a propulsive nozzle to generate the force.

Components such as clutches or gearboxes may be needed to connect the motor to axles, wheels, or propellers. Biological propulsion systems use an animal’s muscles as the power source, and limbs such as wings, fins, or legs as the propulsors. A technological/biological system may use human, or trained animal, muscular work to power a mechanical device.

Among the major components of an EV is the block control of the AC motor.

Many modern high-performance control technologies are being used in EV controllers, such as direct torque control-based space vector modulation (DTC-SVM). Given that permanent magnet synchronous motor (PMSM) has a small volume, a lightweight, and a high reliability, attracting the interest of EV industrial designers. The fault diagnosis about the PMSM problems is essential because the PMSM has a huge influence on the safety and economic efficiency with the vehicles. In this background, the chapter concerns the modeling and simulation of an electric vehicle drive system including a PMSM-based DTC-SVM without and with stator winding fault.
