Case Study: Customized Range Hood Motor for a UK Client

Background
Client Needs: A high-end UK kitchen appliance brand (hereinafter referred to as "the client") planned to launch a quiet range hood tailored to modern British homes, requiring a customized high-performance motor with the following specifications:

Compliance: Meets UK BS EN 61558 (electrical safety standards) and EU CE certification (aligned with UKCA transitional requirements).

Noise Performance: Operational noise below 55 dB (critical for UK open-plan kitchens).

Energy Efficiency: Achieves European Energy Class A+ to reduce long-term costs.

Size Compatibility: Fits the 600mm built-in cabinet design common in the UK market.

Localized Service: Provides UK-based after-sales support and a 2-year warranty.

Challenges

Regulatory Differences: UK residential voltage (230V/50Hz) and stringent safety standards necessitated redesigning circuit protection modules.

Noise Control: Traditional motors reached 65 dB at full load, exceeding the client’s target.

Energy Optimization: Balancing airflow (≥800m³/h) with energy consumption to meet UK users’ environmental priorities.

Installation Compatibility: Low ceiling heights in British kitchens required a compact, flat motor design.

Customized Solutions

Compliance & Safety Design

Collaborated with UK third-party labs to optimize insulation materials and circuitry, securing UKCA certification.

Integrated overload protection to accommodate UK voltage fluctuations (±10%).

Noise Reduction Innovations

Adopted a dual-bearing structure + silicone damping pads to minimize mechanical vibration.

Optimized impeller aerodynamic design, reducing duct noise by 40% and achieving 52 dB.

Energy Efficiency Boost

Utilized brushless DC motor (BLDC) technology, improving energy savings by 30% and increasing airflow to 850m³/h.

Added smart speed adjustment to automatically regulate power based on extending motor lifespan.

Localization Adaptations

Customized motor dimensions (12cm thickness) per client specifications for seamless cabinet integration.

Partnered with UK service providers to establish local spare parts inventory and enable 48-hour

Outcomes & Feedback

Delivery: Completed design-to-mass production in 5 months, with 3,000 units delivered on schedule.

Market Performance: Client’s product sales surged by 25% post-launch, with noise reduction and energy efficiency as key selling points.

Long-Term Partnership: Client placed and expanded collaboration to other product lines (e.g., external motors), extending the partnership to 5 years.
