Bonfiglioli A-series spiral bevel gear right angle servo reduction motor
Product Overview
The A series is a right angle output spiral bevel gear reducer, paired with a Bangfeili BMD permanent magnet synchronous servo motor to form a servo right angle reducer motor; It can also be adapted to third-party servo motors on the market.
Comparison of different driving schemes
Low backlash reducer+servo motor: high dynamic, compact structure, high precision
Standard reducer+servo motor: high compact, medium high dynamic, high efficiency
Reducer+Induction Motor: Rich output forms and diverse combinations
Compared to precision planetary gearboxes: This solution has good performance and better price advantages, suitable for medium to high precision and high dynamic working conditions.
