Abstract

Based on the demand of low-voltage, small-size and high-current motor drive in the vehicle-mounted servo system, the low-voltage and high power density motor drive, which used TMS320F2812 of TI as the control unit, Incremental encoder and small-value, high-power sensor resistor as motor speed and current acquisition unit, low-voltage and high power density MOSFET as driving unit, was designed and implemented. The hardware of driving system was introduced in details, and then the designs of high-density PCB, structure and technology, with relevant speed control of nested segment and parameters testing procedures, were employed to improve the driver integration and reliability. A DC servo motor with a rated current of 20 amps is used as a test motor. The experimental results indicate that the driving system has the advantages of high steady-state accuracy and stable load response.
