AC Servo Motor Distributor
As a professional AC Servo Motor Distributor, we offer a comprehensive range of high-performance servo solutions including the RSDA, RSNA, and RSM series to meet diverse industrial automation needs. Built on optimized SMD magnetic circuit design and high magnetic-density stator and rotor materials, our servo motors deliver high torque density, strong peak torque, low noise, low temperature rise, and excellent energy efficiency. The RSDA series features an ultra-short body design with an optional permanent-magnet brake, making it ideal for space-constrained and Z-axis applications. The RSNA series supports multiple encoder options—optical, magnetic, and multi-turn absolute—ensuring precise feedback and flexible system integration. For medium to high-power applications, the RSM series (110/130 mm flange) provides robust output from 1.2 kW to 1.8 kW with reliable and precise motion control. Together, these servo motor series reflect our commitment to high efficiency, precision, and long-term operational reliability in modern automation systems.
