FANUC BUILT-IN SPINDLE MOTOR BiI series and BiS series make spindles high precision and low vibration with simple mechanical structure.
BiI series has high power up to high speed, therefore it is suitable for spindle of various lathe and machining center.
BiS series is suitable for turning and gear cutting machine due to large torque at low speed by strong neodymium-iron magnets.
*) "I" of BiI means "Induction".
"S" of BiS means "Strong motor with neodymium-iron magnets".
Feature BiI series
- Large torque at low speed and high power at high speed by speed range switching control
- Lower motor temperature by optimum control of magnetic flux.
- Lower noise, lower vibration and higher reliability using the latest winding and casting technique
- Larger torque and higher power available by efficient heat radiation with resin mold and cooling jacket. (Option)
Feature BiS series
- Compact and large torque by neodymium-iron magnets
- Low torque ripple by optimum magnetic circuit design
- High speed and high power using Sub Module SM
- Larger torque and higher power available by efficient heat radiation with resin mold and cooling jacket.
