An indexing/skewing drive system for rotating the motor cores
used for electric motors in automobiles.

SeriesThe 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 tothe motor core, it can index core stacks with high-speed andhigh-torque, while allowing you to set the rotation angle
freely.
With fusion of a servo motor and a cam motion curve, highspeed and a variety rotational stacking build-ups arepossible. This contributes to improved productivity ofhigh-quality motor cores.

Features● High-end model combining high speed, high precision and multiple functions● 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 operationfrom a remote location
Its high precision positioning increases mold life.

● The combination of a servo driven feeder and a servodex device results inmaximum motor core line optimization

260＊1 Indicates the accuracy of a single unit. It does not include the residual vibration that occurs when using a timing belt.
＊2 The capacity changes, depending on the speed ratio and the load being handled. ＊3 Represents the weight of the load.
＊4 Represents the load applied to the center height of the output shaft.
＊5 Use a timing belt that has a low elastic deformation to suppress residual vibration.
＊6 Used for cooling air. ＊7 The capacity varies, depending on the amount of cooling air supplied.
Cooling air is supplied when the motor temperature reaches 60˚C or higher.
