The "heart" of the range hood - The motor
The motor of the range hood is the core component that determines its performance, just like the heart is important to the human body, directly related to the life and condition of a range hood, here is a detailed introduction to the motor of the range hood:
Motor type
◤Induction motor◢
①Single-phase AC motor：Simple structure, low cost, suitable for mid-low-end products. However, it has small starting torque, large running noise, relatively low efficiency, and shorter life.
②Three-phase AC motor：Better performance, large starting torque, stable operation, low noise, high efficiency, long life, but requires a three-phase power source, mostly used in-end or commercial models.
◤DC motor◢
①Brushed DC motor: Simple structure and low cost, but brush wear can cause noise and life issues, gradually being replaced.
②Brushless DC Motor (BLDC): It is the mainstream choice in the high-end market. With extremely low noise, extremely high efficiency, long lifespan, convenient maintenance, and supporting stepless speed change, it can automatically adjust the speed according to the resistance of the flue through the intelligent motherboard, achieving a smart experience of "strong when encountering resistance, quiet when there is no resistance".
Performance of the motor
①Winding material: copper wire motor has good conductivity, low resistance, low heat, strong power, low noise, and long life, which is the standard configuration high-quality motor; aluminum wire motor has low cost, but poor conductivity, easy to heat, fast power decay, and short life.
②Motor lamination (stack number): The higher the stack number (such as 24-stack, 28-stack, 32-, 36-stack, etc.), the larger the rotor volume, the greater the motor power and torque, the stronger the performance, the better the smoke exhaust effect and the more adjustable speed gears. A stack number of 32 or above usually represents mid-to-high-end or top-level performance.
③Motor bearings: ball bearings have superior wear resistance, stability, and lifespan compared to oil-filled bearings. Silent bearings are a hallmark of high- products, achieving ultimate silence and smooth operation.
④Motor structure: Fully enclosed motors can effectively prevent the intrusion of cooking fumes, protecting the internal coils and bearings and extending their lifespan, making them a standard configuration for mainstream brands; semi-enclosed motors are susceptible to corrosion from cooking fumes and are gradually being phased out.
The relationship between motor and range hood performance
①Suction and Wind Pressure: Motor power and speed directly affect the air volume and wind pressure of the range hood. A high-power, high-speed can produce stronger suction and larger wind pressure, ensuring that the smoke is smoothly discharged through the public flue and preventing backflow. Users of high-rise residences in particular to pay attention to the wind pressure index, and it is recommended to choose a model with a wind pressure of 280Pa or above.
②Noise control: High-quality motors, such as brushless DC motors, can significantly reduce operational noise through optimized design and materials, providing a quiet kitchen environment Noise levels are typically measured in decibels (dB), generally not exceeding 72dB.
③Durability: The motor with full copper wire, high stacking number, ball bearings, and fully enclosed structure, combined with good heat dissipation design, can effectively extend motor life, reduce the probability of failure, and lower maintenance costs.
When choosing an electric motor for a range hood, the type, material, number of layers, bearings, and structure are key considerations. Depending on your budget needs, you can prioritize a motor combination of "full copper wire high number of layers ball bearings", or directly choose a high-end product equipped with a brushless inverter motor to get a powerful suction, low noise, and long-lasting durable use experience. If your budget is limited or the usage frequency is not high, a fully aluminum wire motor is also a good choice.
