AiS-B Series

The AiS-B series 2-phase closed loop stepper motor system with built-in brakes are ideal for controlling vertical loads, as the brakes are applied when there are sudden power outages or emergency stops during operation. The closed loop 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. The encoder feedback provides information of the current position in reference to the input pulse with a high resolution of 10,000 pulses per revolution, allowing precise and accurate position control down to 0.036°. The series also features high torque compared to similar in-class models from other brands and various alarm functions for enhanced safety.

Description

  • Brakes are applied during sudden power outages, allowing safe control of vertical loads
  • Low cost closed loop system compared to servo motors with quick response rates for better continuous drive operation
  • Low vibration during low speed drive and high torque during high speed drive
  • No tuning required (easy gain setting using adjuster)
  • Holding torque and no vibration (hunting) during position hold make it ideal for precision machines including optical inspection
  • Various encoder resolutions: 500, 1000, 1600, 2000, 3200, 3600, 5000, 6400, 7200, 10000 (10-stages)
  • Various alarm outputs: overcurrent, overspeed, overheating, motor connection error, encoder connection error, etc. (12 alarms)
  • Frame sizes: 42 mm, 56 mm, 60 mm

※ Applications: semiconductor equipment, 3D printers, optical inspection machines, SMT machines, cartesian robots, conveying equipment, alignment stages, and other precision machines.

Closed Loop Stepper Motor System with Built-in Brake

Brakes are applied during sudden power outages or emergency stops, allowing safer control of vertical loads. The brakes are installed on the center area of the motors, providing more brake power compared to motors with brakes installed in the rear.

Accurate Position Control with Quick Response Rate

The integrated encoder on the motor provides feedback of the current position in reference to the input pulse, allowing extremely accurate and precise control.

Low Vibration During Low Speed Drive

Compared to similar sized models (56 mm) from other brands, the AiS-B series offers lower vibration during low speed drive which results in a quieter and more accurate operation.

High Torque During High Speed Drive

The AiS-B series retains high torque during high speed drive, providing a stable, high power operation.

No Hunting When Holding Position

Unlike conventional servo motors which produce subtle vibrations (hunting) when holding position, the AiS series can hold stop position without vibration (hunting).

10-Stage Resolution for High Precision Control

The AiS series features a 10-stage resolution setting with resolution up to 10,000 pulses per revolution, allowing precise and accurate position control down to 0.036°.

 

Alarm Function (12 Alarm Outputs)

12 alarm outputs are available including overcurrent, overspeed, overheating, motor connection error, encoder connection error, and more.

Applications
