Danfoss Omt 500 Hydraulic Motor

Product Details

📊 Typical Specifications AttributeValue (Typical) Series Danfoss OMT Series Model Size 500 Displacement ~523.6 cm³/rev (≈31.95 in³/rev) Type Low-speed high-torque orbital (geroter) motor Mounting 4-bolt square flange (ISO style) Ports Side ports (e.g., G 3/4 BSP) Drain Port G 1/4 BSP Shaft Straight Ø 40 mm with key (A12 × 8 mm) Bearings Tapered roller (front & rear) Seal Material Standard NBR seals Check Valve Built-in check function Weight (approx) ~25 kg 🔧 Performance (Representative Values) According to typical Danfoss performance charts for the OMT 500: Max Continuous Speed: ~240 rpm Intermittent Speed: ~285 rpm Max Continuous Torque: ~1220 Nm Max Intermittent Torque: ~1370 Nm Continuous Output Power: ~26.5 kW (~35.5 hp) Intermittent Output Power: ~30 kW (~40 hp) Continuous Pressure Drop: ~160 bar Intermittent Pressure Drop: ~180–200 bar These ratings depend on the specific OMT 500 variant and operating conditions (fluid viscosity, temperature, etc.). 🧠 How It Works The Danfoss OMT 500 uses an orbital gear (geroler) design: Oil enters and drives a rotating set of lobed internal gears. The gerolor chamber design produces smooth torque over a wide speed range with built-in check valve support and very good efficiency. Low speed with high torque makes it suitable where slow precision and high turning force are required. Unlike vane or piston motors, orbital motors maintain torque even at very low speeds and are tolerant of load fluctuation. 📦 Typical Applications ✔ Wheel drives and propulsion systems✔ Winches and hoists✔ Conveyors✔ Industrial machinery✔ Sweepers and utility vehicles✔ Agricultural and construction equipment These motors excel in systems requiring robust performance at lower rpm with strong torque output. 🛠️ Options & Variants Danfoss OMT series includes variations such as: Different shaft types: straight or splined Flange variations based on mounting type Brake or speed sensor versions (e.g., OMT FL, OMT EM)These features may change port configuration, drain requirements, or additional functions. 📌 Summary The Danfoss OMT 500 hydraulic motor is a large orbital geroler motor (~524 cc/rev) built for low speed, high torque hydraulic drive applications. It features a durable design with roller bearings, built-in check functions, and a cylindrical shaft — making it suitable for heavy mobile and industrial hydraulic systems.
