A BLAC Motor Drive for EPS System Application

2011
Student Projects

Abstract

EPS systems are more and more used in automotive application to save energy and create a more flexible tool for driver. A BLAC motor has been designed in the Prof. Shen's Laboratory and has a very sinusoidal waveform. In order to avoid the detent torque, a sinusoidal voltage supply has to be provided to the so-called Brushless AC motor (BLAC). The aim of the project is to analyze the possibility to realize this driver and to realize the controller. Control theory and current measurements will have to be carefully analyzed and compared.

Electric motor

An electric motor is an electrical machine that converts electrical energy into mechanical energy. Most electric motors operate through the interaction between the motor's magnetic field and electric current in a wire winding to generate force in the form of torque applied on the motor's shaft. An electric generator is mechanically identical to an electric motor, but operates with a reversed flow of power, converting mechanical energy into electrical energy.

Brushless DC electric motor

A brushless DC electric motor (BLDC), also known as an electronically commutated motor, is a synchronous motor using a direct current (DC) electric power supply. It uses an electronic controller to switch DC currents to the motor windings producing magnetic fields that effectively rotate in space and which the permanent magnet rotor follows. The controller adjusts the phase and amplitude of the DC current pulses to control the speed and torque of the motor.

Stepper motor

A stepper motor, also known as step motor or stepping motor, is a brushless DC electric motor that divides a full rotation into a number of equal steps. The motor's position can be commanded to move and hold at one of these steps without any position sensor for feedback (an open-loop controller), as long as the motor is correctly sized to the application in respect to torque and speed. Switched reluctance motors are very large stepping motors with a reduced pole count, and generally are closed-loop commutated.
