ASC Series | TKK Corporation


ASC Series

The αSTEP utilizes Oriental Motor’s unique closed loop control.
This is a motor and driver package product offering the user-friendliness of a stepping motor combined with improved response and reliability.


  • Incorporating Our Unique Closed Loop Control
  • High Response
  • The motor operates synchronously with pulse commands to achieve high response. There’s no time lag in operation following a pulse command.

  • No Tuning
  • With the ASC Series, you can perform positioning quickly after a load change, etc., without adjusting any gains.

  • No Hunting
  • Because a stepping motor is used, no hunting occurs during stopping.
    Accordingly, this series is ideal for applications where the equipment uses a belt-drive mechanism or otherwise has low rigidity and you don’t want it to vibrate when stopping.
