BMR motor

The BM2 motor is a shaft-distributed cycloidal hydraulic motor, employing a toothed stator-rotor pair and a high-efficiency distribution structure, specifically designed for low-speed, high-torque applications. It boasts advantages such as low starting pressure, smooth operation, sensitive commutation, pressure resistance, leak prevention, and long service life. It is widely applicable to construction machinery, agricultural machinery, injection molding equipment, small vehicles, and hydraulic transmission systems, providing a reliable drive solution for medium-load applications.

Core Advantages

Low-Speed High-Torque Output: Stable high torque at low speeds, smooth heavy-load start-up, and no torque decay under continuous high loads.

High-Efficiency Flow Distribution and Low Loss: Shaft-mounted flow distribution structure ensures precise flow, high mechanical efficiency, lower temperature rise, and lower energy consumption.

Smooth Operation and Low Noise: Cycloidal meshing and precision machining result in smooth operation, low vibration, and low noise.

Strong Sealing and Leak-Free: High-pressure shaft seal and reliable sealing system withstand high back pressure and support series/parallel operation.

Compact Structure and Easy Installation: Small size and light weight; multiple flange, output shaft, and oil port options available for diverse installations.

Durable, Robust, and Long Service Life: Wear-resistant and impact-resistant toothed stator and rotor pair ensures stable and reliable long-term continuous operation.
