H1B series bending shaft variable motor, the motor is designed to be able to form a closed circuit with other products to achieve hydraulic energy transmission and control. A variety of control methods are available to meet the needs of different applications. The starting point of the motor is generally the maximum displacement, which provides the high torque required for high acceleration when the vehicle starts.

High-Speed Capability: Optimized surface treatments, high spring rates, and efficient components allow the motor to operate at high speeds with minimal angles, maximizing performance.
Shortest Unit Length in the Market: The H1B motor boasts the shortest unit length among similar products.
High Quality: It meets quality targets of 250 DPM (defects per million) using IP67 and IP69K-rated electrical components.
Efficiency: Minimized dead volumes, flow-optimized end caps, and valve plates reduce control losses, resulting in improved efficiency.
Robust Construction: The one-piece housing and minimized casing pressure ensure durability. A robust swivel joint enhances dynamic torque capability.
Maximum Pressure: Balanced for a 450-bar pressure differential, allowing high-power operation and increased efficiency.
Ease of Maintenance: External shaft seals simplify maintenance, and the H1 series' modular design provides flexibility for replacements and conversions.
The H1B Bent-Axis Variable Displacement Motor is primarily used in closed-loop systems for hydraulic power transmission and control. Its features include a bent-axis design, spherical pistons, and a maximum displacement ratio of 5:1, with displacements ranging from 60 cm³ to 250 cm³.
