GYS101DC1-CB-B Fuji Electric FALDIC Servo Motor 100W 200V with Brake

The GYS101DC1-CB-B is a 100 W ultra-low inertia AC servo motor designed for compact positioning axes that require both rapid motion response and stationary load holding.

Its slim GYS motor construction supports fast acceleration, quick deceleration and frequent start-stop operation. A 16-bit incremental encoder provides position and speed feedback to the compatible servo amplifier.

The defining feature of this exact model is the integrated electromagnetic holding brake. When correctly controlled, the brake helps prevent shaft movement after the servo has stopped or when motor power is removed.

The CB-B configuration combines a keyless straight shaft with a holding brake, making it suitable for compact vertical axes using clamp-style couplings.

Key Features

• 100 W rated output
• 200 V servo-system configuration
• Ultra-low inertia rotor
• 3000 r/min rated speed
• 16-bit incremental encoder
• Integrated holding brake
• Keyless straight shaft
• Compact flange-mounted construction

Typical Applications

• Vertical positioning axes
• Small lifting mechanisms
• Pick-and-place Z axes
• Inspection equipment
• Compact assembly machines

Integrated Holding Brake

The electromagnetic brake is the main difference between GYS101DC1-CB-B and the standard GYS101DC1-CB.

The brake helps:

• Hold a stopped vertical load
• Reduce movement after power removal
• Maintain the mechanical position during shutdown
• Support machine servicing and setup

The brake is a stationary holding device. It should not be used as the normal method for repeatedly stopping a rotating motor.

Ultra-Low Inertia Design

The GYS Series uses a slim body and low-inertia rotor for responsive motion.

This supports:

• Rapid acceleration
• Rapid deceleration
• Frequent direction changes
• Short positioning cycles
• Lightweight mechanism control

The motor is intended for dynamic compact axes rather than high continuous-torque applications.

Speed and Torque Performance

Rated Output

100 W

Rated Speed

3000 r/min

Maximum Speed

5000 r/min

Rated Torque

0.318 N·m

Maximum Torque

0.955 N·m

Maximum torque is intended for temporary acceleration and deceleration, not continuous operation.

16-Bit Incremental Encoder

The integrated encoder provides feedback for:

• Motor position
• Rotational speed
• Direction of rotation
• Closed-loop servo control

It is an incremental feedback configuration and should not be described as an absolute encoder motor.

Keyless Shaft Configuration

The CB suffix identifies the straight shaft without a key.

This configuration is suited to:

• Clamp-type couplings
• Flexible precision couplings
• Compact low-backlash mechanisms
• Lightweight direct connections

The coupling bore and clamping method must match the shaft dimensions.

They have similar output and brake functions but require different amplifier-voltage configurations.

Brake Control Notes

The holding brake normally requires coordinated control from the servo system.

The control sequence should:

• Energize and release the brake before motion
• Confirm servo torque before releasing a vertical load
• Stop the motor before applying the brake
• Apply the brake before servo torque is removed
• Avoid using the brake for repeated dynamic stopping

Incorrect brake timing may cause load movement or premature brake wear.

Compatibility Checks

Before replacement, verify:

• Complete motor reference
• Servo amplifier model
• 200 V system compatibility
• Encoder cable
• Motor power cable
• Brake cable and brake voltage
• Shaft and coupling type
• Flange dimensions
• Load inertia
• Vertical load requirement

Matching only the 100 W output is not sufficient.

Installation Notes

• Disconnect motor and brake power
• Support vertical loads mechanically
• Verify the keyless coupling
• Align the motor and load shafts
• Do not strike the motor shaft
• Check brake release and engagement timing
• Confirm encoder and motor cables
• Complete servo tuning
• Test brake operation at low load
