GM1-300B Internal Five-Star Motor: Technical Analysis & Translation Optimization
1. Key Information Breakdown
The model"GM1-300B Internal Five-Star Motor"appears to be alow-speed, high-torque (LSHT) hydraulic motorwith a5-lobed internal gerotor/orbital design(common in Chinese manufacturing). Below is a structured breakdown:
【表格】
Component Analysis & Translation
Model Name GM1-300B (likely manufacturer-specific code; "GM" may denote series, "300" displacement, "B" revision)
"Internal" Refers to the star-shaped rotor positioned inside the outer ring (gerotor mechanism).
"Five-Star" Indicates a 5-lobed internal gear/rotor (key to torque efficiency).
"Motor" Confirms it is a hydraulic motor (not electrical or pneumatic).
2. Recommended English Technical Name
To align withglobal hydraulic industry standards, the translation should:
• Avoid literal "Five-Star"(which could imply quality ratings, not technical design).
• Emphasize the gerotor mechanism(critical for torque and efficiency).
Optimized Translation:
"GM1-300B Five-Lobe Internal Gerotor Hydraulic Motor"
(Rationale: "Gerotor" is the recognized term for this internal gear design.)
3. Technical Context & Specifications (Hypothetical Example)
While exact specs are manufacturer-dependent, typical parameters for such a motor might include:
【表格】
Parameter Example Value Explanation
Displacement 300 cc/rev (assumed from "300" in model) Volume of fluid per revolution (affects torque output).
Max. Pressure 250 bar (3,625 psi) Typical for LSHT motors in construction/agriculture.
Max. Torque ~1,200 Nm (885 lb-ft) Derived from displacement × pressure (e.g., 300 cc × 250 bar ≈ 1,175 Nm).
Speed Range 50–500 RPM Low-speed operation for high-load applications.
Mounting Style SAE B or DIN 5482 (common for LSHT) Flange/shaft dimensions for compatibility.
Efficiency 88–92% (typical for gerotor designs) Internal leakage and friction losses.
4. Why "Gerotor" Matters
• Mechanism: Astar-shaped internal rotor(5 lobes) meshes with an outer ring, creatingvariable displacement chambersfor fluid-driven rotation.
• Advantages:
• High torque at low speeds(ideal for winches, conveyors).
• Compact design(fewer parts than gear motors).
• Smooth operation(less pulsation than piston motors).
