YASKAWA ELECTRIC UGRMEM-04SSA71 SERVO MOTOR

Description:

The Yaskawa UGRMEM-04SSA71 is a Minertia RM Series DC servo motor used in industrial robotic and precision motion control systems for high-speed response and low-inertia positioning, commonly installed in CNC machines, robotics, and semiconductor equipment requiring fast acceleration and accurate control, and purchased by maintenance teams, OEMs, and integrators for replacement of legacy Minertia motors and retrofit of high-speed automation systems.

Applications:

The Yaskawa UGRMEM-04SSA71 Minertia motor is used in industrial automation environments where rapid acceleration and precise positioning are critical. It is commonly deployed in robotic systems, semiconductor manufacturing equipment, pick-and-place machines, and CNC positioning systems where low rotor inertia improves cycle time and responsiveness. The RM series is designed for compact, high-performance motion systems with excellent torque-to-weight ratios.
