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

SeriesThe Servo-dex EVR2 series is an indexing/skewing drive
system for rotating the electric motor cores used in homeappliances. It is optimal for electric motor core production
press lines that make motors for home appliances, such as
air conditioners and general-purpose motors.
It reduces mold maintenance by suppressing vibration
when stopping a workpiece with high-precision positioning.
This series can easily be controlled using a timing signal,and various control patterns are now also available.

Features● General-purpose models providing basic performance at a low cost
● Supports optional stacking angle settings and various types of control patterns●●Stacking operation triggered by the timing signal
Its high precision positioning increases mold life.
The combination of a servo driven feeder and a servodex device results in● maximum motor core line optimization

※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.
