ASC Series Closed Loop Stepper Motors

The ASC Series utilizes closed loop control based on Oriental Motor's original Alpha Step technology. With the ASC series there is no hunting or gain tuning required. The built-in rotor position detection sensor constantly monitors the motor movement. If synchronism is about to be lost, closed loop control is used.

No Hunting or Gain tuning
Closed Loop
Geared options
Resolution - 0.72º, 0.36º, 0.072º, 0.036º (Microstep)
24 VDC Power supply input
RoHS compliant
