The GYS101DC1-SB-B is a 100 W AC servo motor from Fuji Electric's FALDIC GYS Series, designed for compact motion systems requiring precise positioning and reliable load holding.
Its ultra-low inertia rotor structure provides fast acceleration and quick response for frequent start-stop operations. The integrated 16-bit absolute/incremental encoder delivers accurate feedback for servo positioning control.
The built-in electromagnetic holding brake is the key difference of this model, allowing the motor to maintain the mechanical position when servo power is removed.
This configuration is especially suitable for vertical axes, lifting mechanisms and applications where accidental movement after power interruption must be prevented.

Ultra-Low Inertia Performance
The GYS series focuses on fast dynamic response rather than only torque output.
The low inertia rotor design provides:
- Faster acceleration
- Faster deceleration
- Shorter positioning cycles
- Improved repeatability
- Smooth high-frequency operation
This makes the motor suitable for compact automation equipment with frequent motion changes.
16-Bit ABS/INC Encoder Advantage
The integrated encoder combines absolute and incremental feedback functions.
Advantages include:
- High-resolution position detection
- Accurate speed feedback
- Reduced positioning error
- Improved servo tuning performance
Compared with standard incremental-only feedback, ABS/INC feedback can simplify machine restart procedures by retaining position information according to system configuration.
Integrated Holding Brake
The built-in brake is the main difference between GYS101DC1-SB-B and standard non-brake versions.
The brake helps:
- Hold vertical loads
- Prevent shaft movement during power-off
- Improve machine safety
- Maintain mechanical position
The brake is designed for holding and should not be used as a dynamic stopping brake.
