Core Competitive Advantages
- Direct Drive Reliability: Simplified mechanism (fewer moving parts) translates directly into a minimal risk of mechanical failure and an extended product warranty period.
- Precise Tumble Control: FOC (Field-Oriented Control) allows for highly accurate torque delivery at very low speeds, essential for delicate cycles and optimal detergent penetration.
- Superior Noise Profile: The lack of brush and belt noise, combined with optimized magnet arrangements, results in an industry-leading quiet washing experience.
- Efficient Use of Space: Direct drive configuration maximizes the drum-to-footprint ratio, allowing for larger wash loads within standard appliance dimensions.
Direct Drive Installation & Scene Guide
- Typical Installation: BLDC Direct Drive: The motor stator is bolted to the rear bulkhead, and the rotor assembly is carefully fitted directly onto the main drum shaft spline/keyway. Critical Step: Accurate torque application when securing the central rotor nut is vital for preventing spin wobble.
- Scenario Optimization: Ideal for premium front-load models installed near living areas (e.g., kitchen or hallway closets) where noise must be kept to an absolute minimum.
- Visual Demonstration: View of the Direct Drive BLDC motor installed on a washing machine drum.
