Bonfiglioli BMS Series Planetary Gearmotor

The Bonfiglioli BMS Series Planetary Gearmotor boasts prominent advantages, serving as a high-performance integrated drive solution for industrial automation scenarios. Its core merit lies in the seamless integration of permanent magnet synchronous motors and precision planetary gearboxes, replacing traditional split combinations to achieve exceptional power density and space-saving effects—critical for compact installation environments. Equipped with hardened alloy steel gears (surface hardness HRC 58-62) processed by five-axis CNC machines, it delivers low backlash, high torsional rigidity, and transmission efficiency up to 97%, ensuring stable and precise operation even in high-frequency cyclic duty cycles.

Lifelong synthetic lubrication and a dual-seal structure (labyrinth + double-lip oil seal) enable an IP65 protection rating, resisting dust and moisture while achieving a 20,000-hour maintenance-free service life, significantly reducing operational costs. With 5 gearbox sizes (060/070/090/130/160) and 14 motor variants, it offers flexible configurations covering 45–1200 Nm torque and 50–1500 rpm output speed, adapting to diverse load demands. Diverse feedback options and optional 24V DC holding brakes ensure seamless integration with servo systems and industrial control protocols. Widely applied in material handling equipment, packaging machinery, textile production lines, and precision automation devices, it excels in scenarios requiring stable torque output, precise positioning, and continuous operation. Backed by Bonfiglioli’s mechatronic expertise, it balances reliability, efficiency, and versatility, becoming an ideal choice for high-demand industrial drive requirements. (400 words)
