Built-in Spindle Motors

The FANUC built-in spindle motors in the BiI-D and BiS-D series deliver high precision and low vibration with a streamlined mechanical design. The BiI-D series supports high power at high speeds, making it ideal for a wide range of applications, including lathes and machining centers. The BiS-D series is designed for turning and gear cutting applications, offering strong low-speed torque thanks to high-performance neodymium magnets.
