The stator of the 2.5kW, 1500r/min compact permanent magnet synchronous motor developed by our company has been successfully built into the workpiece shaft of the user's bearing grinding machine. The application of the new motor eliminates the need for an external motor and belt drive for the user, improves transmission precision, energy efficiency, reduces noise, and provides an effective guarantee for improving the precision of finished bearing products. Luoyang Speed Front Spindle Technology Co., Ltd. is committed to providing spindles, spindle motors, servo motors, high-speed motor products, to help China's manufacturing enterprises to complete the technological upgrading.
