| Abstract |
This paper describes the design and operation of an ASIC controller for brushless dc drives of the trapezoidal type. The integrated circuit controller incorporates both torque and speed control loops in separate dedicated processors. The ASIC itself is designed to encompass a very wide range of applications using the minimum number of external cornponents. The applications include: i) the precise speed control of a 10W motor used in a laser scanner, where speed accuracy of 1 part in 10to6 is required, and ii) control of a 10kW motor used in the feed drive of a multi-axis machine tool, where each axis control unit must interact with a host computer which provides overall supervision of the machine. |
