The system consists of an AC servo motor, an AC spindle motor, and a servo amplifier. Through advanced nano control technology and HRV control algorithm, it provides excellent dynamic response and machining accuracy for various CNC machine tools.

The α i-B series is positioned as a high-performance servo system, suitable for high-power and high torque applications such as large machine tools, presses, injection molding machines, etc; The β i-B series provides sufficient performance and cost-effectiveness to meet the machining needs of general machine tools. Both series offer 200V and 400V input voltage options to adapt to power supply standards in different regions.

Communication servo motor: the power core of the feed axis

2.1 α i-B series high-performance servo motor

The α i-B series servo motor is designed to meet the requirements of high-precision and high-efficiency machining:

Excellent processing performance:

Adopting an ultra-high resolution pulse encoder of 32000000/rev, combined with a special magnetic pole shape to minimize torque ripple, and the latest HRV+servo control, extremely smooth motor rotation is achieved, achieving high-precision and high-quality surface processing.

Through the "multi amplifier drive technology", a single axis can achieve a high torque of up to 18000Nm and a high power output of 500kW.

By utilizing 'multi motor drive technology', the single axis output capability is further enhanced, making it suitable for heavy-duty applications such as large machine tools, presses, and injection molding machines.

Minimize downtime: Adopting Fanuc's unique sealing structure, it provides excellent waterproof performance, with an optional IP67 waterproof rating to adapt to harsh cutting fluid environments.

Usability:

Optional battery free pulse encoder, no need to backup battery.

Adopting a one click connector for easy insertion and removal of power connectors.

Optional back clearance reducing brake.

2.2 β i-B series cost-effective servo motor

The β i-B series servo motor provides higher cost-effectiveness while ensuring sufficient performance:

Equipped with a 1000000/rev pulse encoder, combined with special magnetic pole shapes and HRV+control, to achieve smooth motor rotation.

The unique sealing structure of Fanuc is also adopted, with an optional IP67 waterproof rating.

We offer multiple models of 200V and 400V, with optional battery free pulse encoders and support for one click connectors.

Communication Spindle Motor: Efficient Solution for Main Drive

3.1 α i-B series high-performance spindle motor

The α i-B series spindle motor achieves high speed and fast acceleration and deceleration through optimized winding design and effective cooling structure:

Short time rated output: By increasing the short-term rated output and torque, the short-term heavy cutting capability is improved and the acceleration and deceleration time is shortened. Fanuc's unique spindle control ensures that S6's short-term rated output is equivalent to S3.

Diversified models: Provide hollow shaft models with center water cooling (suitable for center coolant), including air-cooled i-B series and liquid cooled i-B series.

High power output: Through "multi amplifier drive technology", the maximum output power can reach 200kW and the maximum torque can reach 2000Nm. The output can be further improved through "multi motor drive technology".

Special model: Provides synchronous spindle motors suitable for frequent and rapid acceleration and deceleration, as well as spindle motors suitable for lathes that can withstand larger radial loads.

3.2 β i-B series cost-effective spindle motor

The β i-B series spindle motor provides high power and torque in a compact size, suitable for general machine tools:

Optimized winding design and cooling structure to achieve high power density.

By increasing the short-term rated output and torque, the short-term heavy cutting capability is improved and the acceleration and deceleration time is shortened.

Provide a hollow shaft model with central water cooling, which has sufficient mechanical accuracy and low vibration, and can be directly connected to the machine tool spindle.

Servo amplifier: the core of intelligent driving

4.1 α i-B series high-performance servo amplifier

The α i-B series servo amplifier offers a wide range of options from small to large capacity:

Processing performance: Adopting high-power, high-precision current control to achieve short-term processing and high-precision, high-quality processing.

Minimize downtime:

Built in leakage detection function can detect insulation degradation of motors in harsh coolant environments.

The fan motor can be easily replaced from the front.

The troubleshooting function helps quickly identify the cause of the alarm.

Usability:

By using the safety torque shutdown function, the electromagnetic contactor used for cutting off external power can be eliminated.
