Abstract

To design motor drives tor optimal motion control, and to obtain precise Brushless Direct Current motor model, accurate measurement of motor parameters like phase current, speed and torque is required. They are also desired to provide feedback between the BLDC motor and its controller to develop robust BLDC motor control algorithm. In this paper, phase current, speed and torque measurement technique for Hub BLDC motor is presented to analyze its performance for low power electric vehicle applications. For the phase current measurement. the Hall-Effect current sensor ACS712 is used. The speed of the motor is calculated using internal hall sensor that is connected to dsPIC33F's input capture pin that generates an interrupt whenever a change in the hall sensor signal value occur. Further, an experimental setup is established in the laboratory to measure the torque at varying load and to determine the relationship between motor torque, input current, output power, speed and efficiency.
