GYS101DC1-C6B Fuji Electric FALDIC-Beta Servo Motor 100W 100V

The GYS101DC1-C6B is a 100 W ultra-low inertia AC servo motor from the Fuji Electric FALDIC-Beta GYS Series.
Its defining difference is the 100 V servo-system configuration. Unlike the more common 200 V GYS101DC1-CB model, the C6B version is intended for a compatible single-phase 100 V servo amplifier.
The slim motor body and low-inertia rotor support rapid acceleration, short positioning cycles and frequent direction changes. A 16-bit serial incremental encoder provides position and speed feedback for closed-loop servo control.
This exact model has a straight shaft without a key and does not include an electromagnetic holding brake.

100 V Servo-System Configuration
The C6B suffix identifies the 100 V version within this GYS motor group.
It is intended for a compatible 100 V servo amplifier and must not be selected only by matching the 100 W output rating.
Before replacement, verify:

• Amplifier input voltage

• Motor output rating

• Encoder compatibility

• Motor power cable

• Encoder cable

• Shaft and flange dimensions

GYS101DC1-C6B is not a direct replacement for a 200 V motor unless the complete servo system is changed accordingly.
Ultra-Low Inertia Design
The GYS Series uses a slim motor body and low-inertia rotor for responsive motion.
This design supports:

• Rapid acceleration

• Rapid deceleration

• Frequent start-stop cycles

• Short movement profiles

• Lightweight load positioning

It is better suited to small dynamic axes than applications requiring high continuous torque.
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 available for temporary acceleration and deceleration and is not a continuous operating value.
16-Bit Incremental Feedback
The integrated 16-bit serial encoder provides feedback for:

• Motor position

• Rotational speed

• Rotation direction

• Servo-loop control

It is an incremental encoder configuration and should not be advertised as an absolute encoder motor.
Keyless Shaft Configuration
GYS101DC1-C6B uses a straight shaft without a key.
This configuration is suitable for:

• Clamp-style couplings

• Low-backlash couplings

• Lightweight positioning mechanisms

• Compact direct-drive connections

The coupling bore and clamping method must match the motor shaft.
Non-Brake Configuration
GYS101DC1-C6B does not contain a holding brake.
It is suitable for:

• Horizontal axes

• Non-suspended mechanisms

• Systems with an external holding device

• Applications that do not require load retention after power removal

For an integrated holding brake, the correct model is GYS101DC1-C6B-B.
Protection Structure
The standard motor construction is IP55, excluding the shaft penetration and connector sections.
The motor should therefore be installed where:

• Direct water jets are avoided

• Connector areas remain protected

• Oil and coolant exposure are controlled

• Cable connections are properly secured

It should not be described as an IP65 motor without documentation for that exact supplied version.
GYS101DC1-C6B vs GYS101DC1-C6B-B
GYS101DC1-C6B
100 W
100 V class

GYS101DC1-C6B
100 V servo-system version
Keyless shaft
No brake
GYS101DC1-CB
200 V servo-system version
Keyless shaft
No brake
Their output and speed are similar, but the compatible amplifier voltage is different.
GYS101DC1-C6B vs GYS101DC1-C6A
GYS101DC1-C6B
Straight shaft without key
GYS101DC1-C6A
Straight shaft with key
The primary difference is the shaft-end configuration.
Compatible Amplifier
Official product information associates GYS101DC1-C6B with the compatible 100 V FALDIC-Beta servo amplifier reference:
RYB101S3-VBC6
Amplifier firmware, cables and machine configuration must still be checked before installation.
Legacy System Replacement
GYS101DC1-C6B belongs to a legacy FALDIC-Beta servo platform.
For replacement work, confirm:

• Original motor nameplate

• Existing amplifier reference

• Feedback cable

• Motor power connector

• Mechanical dimensions

• Shaft coupling

• Brake requirement

• Controller interface

A newer 100 W motor may not be electrically or mechanically interchangeable.
Installation Notes

• Disconnect all servo-system power

• Confirm the system is 100 V class

• Verify the motor has no brake

• Use a suitable keyless coupling

• Align the motor and load shafts

• Avoid impacts on the shaft

• Protect connector and shaft areas

• Complete servo tuning after replacement

• Test direction at low speed

FAQ
Q1: What is the rated output of GYS101DC1-C6B?
A1: The rated output is 100 W.
Q2: Is this a 100 V or 200 V motor?
A2: It is the 100 V servo-system version.
Q3: What encoder does it use?
A3: It uses a 16-bit serial incremental encoder.
Q4: Does GYS101DC1-C6B include a brake?
A4: No. The brake-equipped reference is GYS101DC1-C6B-B.
Q5: What is the shaft configuration?
A5: It uses a straight shaft without a key.
