HS Code: 8431390000
This is a highly integrated power transmission device. It seamlessly combines an AC220V single-phase motor, a reduction mechanism (if applicable), and the drive roller into a compact cylindrical unit. Its core feature is the "direct-drive" technology, which eliminates traditional external transmission components such as separate motors, belts, chains, or gearboxes. It directly utilizes the roller body itself as the motor's rotor to generate rotational output power.
Outer Casing (Stator Section): The outer shell of the roller remains stationary. Inside, the motor's stator windings are embedded. When AC220V power is supplied, a rotating magnetic field is generated.
Roller Body (Rotor Section): The roller's cylinder (typically made of steel or coated with rubber) acts directly as the motor's rotor. Under the influence of the rotating magnetic field, the cylinder begins to rotate directly.
Bearings and End Caps: Support the entire rotating cylinder, ensuring smooth and low-noise operation.
Integrated Reduction Mechanism (Optional): Some models integrate a planetary or harmonic gear reducer between the motor and the roller cylinder to achieve higher torque and lower output speed. For high-speed, low-torque applications, a purely direct-drive method without reduction may also be used.
Connection Box: Usually located on the end cap at one side of the roller for connecting the AC220V power cable. Some advanced models may integrate speed control or communication interfaces.
Extremely Compact Structure, Space-Saving: All drive components are built-in, greatly simplifying overall equipment design, especially suitable for space-constrained applications.
High Transmission Efficiency, Energy-Saving: Eliminates energy losses from intermediate transmission links (e.g., belt slippage, gear friction). Energy transfer is more direct, with efficiency typically reaching over 80%.
Smooth and Quiet Operation: No belt flutter or chain meshing noise, with minimal mechanical vibration.
Maintenance-Free, High Reliability: Excellent overall sealing with high protection ratings (common IP54, IP65), offering dust and water resistance. Internal components require no lubrication, eliminating the need for periodic maintenance like adjusting belt tension, replacing chains, or adding lubricant as in traditional drive systems.
Simple Installation: Simply fix the roller to the frame via the shaft ends or flanges on both sides, connect the power, and it's ready to operate. This significantly reduces installation time and cost.
Enhanced Safety: Rotating parts are completely enclosed, with no exposed belts or chains, reducing pinch hazard risks.
Clean and Hygienic: No oil seepage, complying with sanitary requirements in industries like food and pharmaceuticals.
Logistics Conveyor Systems: Primary drive unit for belt conveyors and roller conveyors.
Food Processing and Packaging Machinery: Conveyor lines with high cleanliness requirements.
Postal Sorting Equipment: Cross-belt sorters requiring frequent starts/stops and smooth operation.
Airport Baggage Handling Systems: Applications demanding high reliability and long service life.
Light Industrial Assembly Lines: Assembly conveyors for products like electronics and appliances.
Printing and Paper Machinery: Used as drive rollers for winding or conveying.
Power Supply: AC 220V, 50/60Hz (Single-phase).
Roller Diameter: Ranges from 50mm to several hundred millimeters.
Roller Length: Can be customized based on conveyor belt width.
Power Range: Typically between 0.1kW and 3.0kW.
Output Speed: Determined by motor poles and built-in reduction ratio. Common range from approximately 10 rpm to 200 rpm.
Torque Output: Correlates with power and speed; a core parameter for selection.
Protection Rating: e.g., IP55 (dust and water resistant), IP66 (strong dust and water resistance).
Surface Treatment: Plain steel, galvanized, rubber-coated (plain rubber, diamond pattern rubber, polyurethane rubber, etc., to increase friction).
Optional Features: Electromagnetic brake (power-off braking), variable frequency speed control, thermal protection, etc.
Heat Dissipation: As the motor is built-in, heat dissipation is limited. Attention must be paid to the duty cycle (e.g., S1 continuous or S3 intermittent) and ambient temperature to avoid overheating from overload.
Load and Start-up: Starting torque is usually lower than rated running torque. Special calculation and selection are required for heavy-duty start-up applications.
Maintenance/Repair: If the internal motor fails, repair is complex. Typically, the entire unit needs to be returned to the factory or replaced. Therefore, choosing a high-quality brand from the outset is crucial.
