Product Description:

This R34KEAC-HS-NG-NV-00 Servo Motor is produced by Pacific Scientific which is a trusted name in creating advanced tools like frequency inverters, servo drives, gear motors and industrial automation systems. Its products are widely used where high precision is needed.

The R34KEAC-HS-NG-NV-00 servo motor is designed with a compact 3.25-inch square frame and fits into various mechanical systems. Its 4-inch stack length optimizes performance without compromising space efficiency. It is equipped with a K-type winding and includes a standard shaft and mounting configuration by facilitating easy integration into existing setups. It offers a 24V DC holding brake option by providing secure positioning during power loss. Feedback is critical for accurate motion control and this R servomotor series model excels with dual feedback systems. The primary feedback relies on Hall sensors for reliable commutation signals while the secondary feedback utilizes a 1024 PPR encoder with line driver output for precise speed. It lacks a shaft seal but still works best with a stall torque of 27.0 Nm and a peak torque of 3.0 Nm. It is certified with UL and CE markings and follows international standards.

The R34KEAC-HS-NG-NV-00 servo motor’s continuous stall current is 7.5 Amps and works at 320 VDC for optimal energy conversion. This motor delivers strong and consistent power with a voltage constant rated at 47.0 V/krpm while the resistance measures 2.00 Ohms by supporting an efficient thermal system. Designed for rigorous applications, the motor runs at a rated speed of 4000 RPM by producing an output power of 0.76 kW. It can handle peak currents up to 9.0 Amps. It operates in temperatures as low as -25°C and complies with insulation class F standards by ensuring durability and longevity.
