AiSA Series - AC Power 2-Phase Closed Loop Stepper Motor System
AiSA Series AC Power 2-Phase Closed Loop Stepper Motor System

The AiSA series is an AC powered 2-phase closed loop stepper motor system featuring integrated drivers. The AC powered motor system can maintain higher torque during high speed drive compared to DC type motors and do not require separate switching mode power supplies. The automatic current down function reduces the electric current when the motor stops (load change) to minimize heat generation.

Closed Loop Stepper Motor Control
The stepper motor system offers accurate and precise position control through feedback from the integrated encoder without the hassle of tuning and vibration of conventional servo motors.
AC Power Supply
AC power supply closed loop stepper motor system can maintain higher torque during high speed drive compared to DC type motors. The motors also do not require separate power supplies, allowing more flexible installation options.
Auto Current Down Mode
Auto current down mode reduces the electric current when the motor stops (no load) to minimize heat generation.
Torque Control Mode
Torque control mode allows accurate operation of machinery by maintaining the initial torque set during motor operation.
Easy Tuning Using External Adjuster
Users can easily change operation settings and range directly using the external adjuster
Built-in Brake Type Motors Available
The built-in brake type motor and drivers allow safer control of vertical loads. The brakes are located towards the rear and the separate brake connector allows easy connection.
