Abstract
Ultra-high-speed motors play a very important role in machine tools. A speed-sensor-less ultra-high-speed motor driver is proposed in this paper. Without any speed sensor that is extremely expensive, the proposed driver employing a sensor-less estimation scheme can perform a closed-loop control very accurately and efficiently. The design and implementation of the driver and feedback circuits are detailed in this paper. Experimental results show that the proposed system functions very well.
