BiI-B Series
Asynchronous built-in spindle motors for high performance
Compact built-in motors for compact, high speed, and high performance machines with best adaption in mechanical machine design.
Key Features:
- Large torque at low speed – high power at high speed
- Power range 0.75-50kW
- Larger torque and higher power achieved by efficient heat radiation of stator resin mold (option) or copper-bar rotor (some models)
- Maximum speed up to 70000 rpm
BiS-B Series
Synchronous built-in spindle motors for high Torque
Compact built-in motors with high torque for tough material (e.g. Titanium) and heavy cutting processes.
Key Features:
- Large torque at low speed – strong neodymium magnet rotor structure
- Power rating 11 – 80 kW
- Low ripple – optimum magnetic circuit design
- Larger torque and high power achieved by efficient heat radiation of stator resin mold
- Best suitable for lathe and gear cutting
- maximum speed – 33000 rpm
