CNC Spindle Motors

All FANUC BETA i-B Series spindle motors are induction-type. The available motor and amplifier combinations provide adequate power and low-cost for economical machines. The design of the motor winding and very effective cooling structure provide for large amounts of both power and torque in a compact size.

BETA i-B Series spindle motors feature:

• Available models: standard, ‘P’ (power) and ‘T’ (through-coolant)
• 200V or 400V input voltage
• 200V or 400V input voltage
• Torque output 14-323 Nm
• Power output 2.2-22 kW
• V5 vibration class for smooth rotation
• Motor rear can be re-balanced after coupling to spindle for minimal vibration
• Up to 12,000 RPM
• Noise 75 dB or less
• IP54 protection

FANUC ALPHA i-B Series spindle motors are available in induction- and synchronous-type. The available motor and amplifier combinations provide substantial power and torque for high-performance and large machines; multiple amplifiers can be combined for very large power applications. The design of the motor winding (multiple windings on some models) and very effective cooling structure provide for huge amounts of both power and torque in a compact size.

ALPHA i-B Series spindle motors feature:

• Available models: standard, ‘P’ (power), ‘T’ (through-coolant), and ‘L’ (liquid-cooled)
• 200V or 400V input voltage
• Torque output 3.5-2,800 Nm
• Power output 0.55-280 kW
• V3 vibration class for ultra-smooth rotation on most models, V5 with V3 optional on remaining
• Motor rear can be re-balanced after coupling to spindle for minimal vibration
• Up to 24,000 RPM
• Noise 75 dB or less
• IP54 protection, IP65 optional on some models

FANUC B i-B Series frameless spindle motors are available in induction- and synchronous-type. The available motor and amplifier combinations provide unmatched power and torque, relative to size, for machines of every type; multiple amplifiers can be combined for very large power applications. Stators are available with or without integrated cooling jackets. Available water cooling provides 20% higher output and 25% less temperature rise over oil cooling.

Bi-B Series spindle motors feature:

• Available models: BiI-B (induction) and BiS-B (synchronous)
• 200V or 400V input voltage
• Torque output 0.075-1,694 Nm
• Power output 0.5-150 kW
• Up to 80,000 RPM
• Vibration-free design
