Brief Product Description

Yaskawa UGRMEM-01SNQ12 is a coreless DC servo motor from Yaskawa UGR series, designed for high-precision, low-inertia motion control applications. Featuring hollow cup armature construction, this motor delivers ultra-smooth rotation, fast dynamic response and low torque ripple. Integrated with built-in encoder for closed-loop position and speed feedback, it pairs with matching Yaskawa servo amplifiers for precise speed, position and torque control. Compact size and high acceleration capability make it suitable for automated machinery requiring rapid start-stop motion. With sealed construction and robust mechanical design, it supports continuous 24/7 operation in factory automation environments. Fully tested surplus and refurbished Yaskawa UGRMEM-01SNQ12 motors are available for legacy motion system maintenance, servo motor replacement and machine retrofit projects.

FAQ (Frequently Asked Questions)

• Q: Motor jitter, speed fluctuation or encoder alarm after installing UGRMEM-01SNQ12?
  A: Inspect encoder cable and connector, check shaft mechanical binding, verify servo drive parameter tuning, inspect bearing wear and check grounding to reduce EMI noise.
• Q: Does Yaskawa UGRMEM-01SNQ12 support hot-swap replacement?
  A: Hot swap is not permitted. Disconnect motor power and encoder wiring, perform lockout-tagout and release mechanical load before replacement to prevent unexpected rotation and injury.
• Q: What type of motor is UGRMEM-01SNQ12?
  A: It is a Yaskawa UGR series hollow coreless DC servo motor with integrated encoder feedback.
• Q: What is the main advantage of coreless DC servo motor?
  A: Low rotor inertia, fast acceleration, minimal cogging torque and ultra-smooth low-speed rotation.
• Q: Is Yaskawa UGRMEM-01SNQ12 available for new automation projects?
  A: This legacy UGR series DC servo motor is end-of-life for new installations. Only fully tested surplus and refurbished units are supplied for existing motion control system maintenance and retrofits.
