Description
Product Overview
The Yaskawa HV-75AP4 represents the cutting edge of industrial servo motor technology, delivering exceptional power density and precision for heavy-duty automation applications. As part of Yaskawa’s H-Series of high-voltage servo motors, this 75kW model is engineered to meet the demanding requirements of large-scale CNC machinery, heavy industrial robots, and high-speed production lines where torque and reliability are paramount.
The HV-75AP4 features a permanent magnet synchronous motor (PMSM) design with Yaskawa’s proprietary magnetic circuit optimization, achieving 95% energy efficiency while maintaining ±0.01° positioning accuracy. Its liquid-cooled construction allows continuous operation at full torque even in high ambient temperatures, making it ideal for foundries, metal processing plants, and other challenging industrial environments.
With built-in high-resolution encoder (24-bit absolute) and vibration suppression technology, the Yaskawa HV-75AP4 ensures smooth operation at speeds up to 2,000 rpm while delivering 1,500 Nm of peak torque. The motor’s IP67-rated housing provides complete protection against dust ingress and temporary immersion, while special surface treatments resist corrosion in harsh chemical environments.
