Mechanical Absolute Sensor ABZO Technology in AZ Series Stepper Motors
Oriental Motor αSTEP AZ series closed-loop stepper motors integrate proprietary ABZO mechanical absolute multi-turn sensor technology.
Unlike optical encoders requiring external backup batteries, the ABZO sensor records angular displacement via an internal mechanical gear train where each gear tracks individual angles without power. Upon complete power interruption, gear mechanical positions remain locked.
When power is restored, the drive controller reads absolute coordinates without executing home-seeking sensor return routines. Eliminating backup batteries cuts maintenance expense and guarantees stable operation across temperatures from 0 to +40 °C.
Closed Loop Architecture and Stall Prevention in αSTEP AR Motors
The αSTEP AR series bridges the affordability of stepper motors with the dynamic stability of AC servo systems. An integrated rotor position sensor continuously streams feedback to the digital driver, which commands the motor in microstepping mode with minimal phase lag.
When encountering unexpected load spikes, the driver automatically engages closed-loop current control, regulating phase current to prevent step loss and motor stalling. If high overload persists, the drive generates a dedicated alarm signal.
Adaptive current regulation keeps motor operating temperatures lower under continuous cyclic indexing.
Gearhead Matching GN, GU and JH/JL for 5IK and World K Induction Motors
Oriental Motor standard AC induction and reversible motors series 2IK, 3IK, 4IK, and 5IK pair with parallel and right-angle gearheads to reduce speed while multiplying output torque.
