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
