Technical Specifications

Product Features

Galvanized Metallic Architecture: The motor casing is constructed from high-grade galvanized steel, utilizing a specialized assembly process designed to maximize structural rigidity. This provides exceptional resistance against mechanical warping and long-term protection against galvanic corrosion and rust in high-humidity exhaust streams.

Backward-Curved Aerodynamics: Engineered with a precision single backward-curved impeller. This specific aerodynamic geometry is highly efficient at generating high static pressure, ensuring that volumetric airflow remains powerful and stable, preventing motor stalling even when pushing air through restrictive, multi-bend ducting networks.

Class 180 Thermodynamic Protection: Fortified with industrial-grade Class 180 (Class H) winding insulation. This extreme thermal management system allows the copper windings to operate safely under intense, continuous-duty thermal loads up to 180°C without risking degradation, making it ideal for high-BTU cooking environments.

Capacitor-Less OEM Architecture: Engineered without an internally mounted capacitor, this configuration provides a streamlined electrical interface. It grants OEM electrical engineers the flexibility to integrate capacitance externally, directly onto proprietary appliance PCB switchboards, optimizing the internal spatial design of the hood chassis.

Dynamic Variable Speed Control (1 to 8 Stages): Utilizing a highly adaptable single-phase AC configuration, the motor supports a versatile matrix from 1 to 8 distinct RPM speeds. This allows appliance manufacturers to map highly precise, energy-efficient extraction curves tailored to premium, multi-tiered ventilation models.

Global Export Readiness (50/60Hz): Dual-rated to operate flawlessly across a 220V–240V envelope at both 50 Hz and 60 Hz frequencies. This electrical versatility ensures seamless international distribution and consistent performance across diverse global power grids without the need for localized rewiring.

Integrated Thermal Overload Shield: Features an in-line thermal protector that continuously monitors internal coil temperatures. During temporary duct blockages or severe ambient heat spikes, the circuit safely interrupts and automatically resets, preventing catastrophic thermal failure.

Installation & Maintenance

Assembly Line Integration for OEMs: This motor is engineered to provide extreme structural stability during high-volume appliance manufacturing. The heavy-duty galvanized metallic casing offers highly rigid mounting points, preventing any chassis warping when secured within the range hood canopy. Furthermore, the capacitor-less electrical architecture provides OEM assembly technicians and electrical engineers with a cleaner wiring protocol, allowing capacitance to be routed directly through proprietary appliance control boards and optimizing internal spatial design.

Maintenance Profile in Heavy-Duty Applications: Designed specifically for continuous extraction over high-BTU gas ranges, the K30 1113/1117 operates with a near-zero maintenance footprint. The specialized galvanized assembly intrinsically prevents the formation of localized rust and galvanic corrosion, even in highly saturated, moisture-heavy exhaust streams. Aerodynamically, the backward-curved impeller is naturally resistant to grease particulate accumulation and rotational imbalance compared to standard forward-curved blades. Combined with the extreme thermodynamic resilience of the Class 180 insulation and the auto-resetting in-line thermal protector, this motor significantly reduces the frequency of physical maintenance interventions and post-sale warranty claims.

FAQ

Why combine a backward-curved impeller with a galvanized metal housing? OEM engineers frequently face a compromise: plastic blowers offer backward-curved aerodynamics for high static pressure, while metal blowers offer superior structural rigidity but typically use forward-curved blades. The K30 Galvanized Backward-Curved Range Hood Motor resolves this by housing a high-pressure backward-curved impeller inside an ultra-durable galvanized metal chassis, providing both extreme aerodynamic performance in restrictive ducts and uncompromising physical longevity.

What specific thermodynamic advantage does Class 180 (Class H) insulation offer? Class 180 insulation ensures the motor’s copper windings can safely operate at extreme temperatures up to 180°C without risking thermal degradation. This extreme rating is essential for heavy-duty appliances installed over prosumer gas ranges, where continuous, high-heat extraction cycles rapidly degrade standard Class 130 or 155 motors.

How does the capacitor-less electrical design benefit our appliance manufacturing? By omitting the internal capacitor, the motor provides a highly streamlined electrical interface. This allows your electrical engineering team to integrate the exact capacitance requirements directly into the appliance’s main electronic PCB or control board, centralizing the electrical architecture and freeing up valuable physical space.

Does the galvanized metal construction truly resist rust in heavy-duty kitchen exhausts? Yes. Traditional metallic blowers often suffer from galvanic corrosion at spot-welded joints where the protective zinc coating is destroyed. Our specialized galvanized assembly process preserves the structural and chemical integrity of the zinc layer, offering superior, long-term resistance to rust and oxidation in high-humidity and coastal environments.

Can the 1-to-8 speed settings be mapped to our proprietary electronic touch panels? Absolutely. The motor utilizes a universally adaptable single-phase AC configuration. OEM engineers can seamlessly map the distinct speed taps (from 1 up to 8 stages) to align precisely with proprietary capacitive touch interfaces, digital displays, or variable mechanical relays, providing extensive product tiering flexibility from a single physical component.

What is the international supply capability for this specific OEM component?
