A mixer truck works around wet concrete all day — every hydraulic drive on the vehicle has to be compact, sealed, and mounted with as few leak points as possible, while still delivering steady torque against a load that changes with every batch.

Motor roles in this machine

• BM3Y — discharge / auxiliary drive: The Y-variant of the BM3 heavy-duty orbital motor mounts by direct flange — no coupling, no extra leak points — and sustains 250–800 N·m continuously at 30–150 r/min. BM3 reference →
• Steady torque under varying load: Concrete density varies batch to batch; the orbital gear set keeps output speed stable without stalling as resistance climbs.
