The Servo-dex EVR1 series is an indexing or skewing drive system for rotating the motor core for production lines making motor cores for hybrid, PHEV, and EV car motors.
By connecting a high-performance servo motor directly to the motor core, it can index core stacks with high-speed and high-torque, while allowing you to set the rotation angle freely.
With fusion of a servo motor and a cam motion curve, high speed and a variety rotational stacking build-ups are possible. This contributes to improved productivity of high-quality motor cores.

EVR1 Series（3 models）

| EVR1-160 | EVR1-230 | EVR1-310 |

World-class performance using a high-performance motor
Outstanding reliability due to our original vibration damping design
It also supports arbitrary rotation angle settings, and skew processing of the motor core
The communication function allows you to check the status of the operation from a remote location

The combination of a servo driven feeder and a servo-dex device results in maximum motor core line optimization
