BM3 Heavy-Duty LSHT Orbit Motor
The entry frame of the BM3–BM6 heavy-duty family — direct-mount flange eliminates the intermediate gearbox, with output-shaft and wheel-type builds and the BM3Y variant for outrigger and unloading drives.
The BM3–BM6 family carries the orbital principle into heavy duty — up to 3,000 N·m continuous rated torque across the family, with a direct-mount flange that removes the coupling and gearbox from the drivetrain entirely.
The BM3Y variant is proven in grain truck unloading augers — sustained 250–800 N·m at 30–150 r/min with no leak points in food-grade environments — and in concrete pump outrigger extension drives.
Speed sensor option available for closed-loop anti-stall control.
