Driven by the dual impetus of consumption upgrading and demand for healthy hair care, high-speed hair dryers, leveraging their core advantages of "fast drying, low-damage hair care, and low-noise operation", are gradually replacing traditional hair dryers to become the market mainstream. However, the performance breakthrough of high-speed hair dryers highly depends on the technical capabilities of core control chips. Traditional solutions often suffer from issues such as unstable speed control, low energy efficiency, and high noise. Fortunately, the high-speed hair dryer application solution based on AT32F421 MCU launched by Artery Technology precisely addresses these pain points, providing the industry with a high-performance and highly reliable control core.
Artery AT32F421 MCU: The "Intelligent Brain" of High-Speed Hair Dryers
In response to the market trend of high-speed hair dryers, Artery has tailor-made an application solution supporting an ultra-high rotation speed of 100,000 - 120,000 rpm, with the core lying in the powerful performance and refined control capabilities of the AT32F421 MCU. Based on the Cortex-M4 core, this chip features a main frequency of up to 120 MHz and a large-memory design, enabling it to efficiently process complex algorithms and lay a solid foundation for the stable operation of high-speed hair dryers.
1. Core Control Technology: Sensorless FOC Vector Control, Balancing Performance and Experience
l Wide-range Precise Speed Control: The speed control range covers 10,000 - 120,000 rpm, which can not only meet the low-speed gentle mode for daily hair drying but also realize the high-speed fast hair drying demand, providing sufficient flexibility in air volume adjustment.
l Robust Load Adaptation: In scenarios with large load changes such as hair tangling and air duct resistance variation, it can still maintain stable rotation speed, avoiding problems like "stuttering and sudden drop in rotation speed" that occur in traditional hair dryers.
l Low Noise and Low Fluctuation: By optimizing torque fluctuation control, it significantly reduces motor operation vibration and noise. Meanwhile, it minimizes the damage of high-speed airflow to hair cuticles, achieving both "fast drying" and "hair care".
2. Application Features: Detailed Optimization to Enhance Solution Reliability
In terms of hardware design and function implementation, Artery's solution fully considers the actual application scenarios of high-speed hair dryers and has multiple features:
l Flexible Current Sampling: It supports single-resistor or dual-resistor sampling, balancing cost and detection accuracy. Combined with a 2 Msps high-speed ADC (Analog-to-Digital Converter), it realizes accurate real-time current detection.
l Efficient Signal Processing: The fast current loop calculation capability can reduce current harmonics and motor vibration. At the same time, the high PWM frequency of 20 kHz - 30 kHz ensures the smooth operation of the motor.
l Upgraded Safety Protection: It integrates a built-in comparator in the chip, which can easily implement Over-Current Protection (OCP), avoiding equipment damage caused by motor overload or short circuit and improving product safety.
3. Solution Advantages: Streamlined Design to Lower Development Threshold
The hardware integration and software adaptability of the AT32F421 MCU provide convenient development support for high-speed hair dryer manufacturers:
l Streamlined Circuit Design: The advanced timer can directly output multiple channels of complementary PWM signals, and there is no need for additional logic chips to drive the power module (IPM). This reduces the number of peripheral components and lowers the PCB board area and cost.
l Rapid Algorithm Implementation: The high main frequency and large memory enable the rapid completion of FOC algorithm and speed adjustment. Cooperated with the Luenberger observer + Q-PLL angle estimation method, it realizes accurate judgment of the motor rotor position and shortens the development cycle.
l Wide Adaptability: It supports 220V_AC AC permanent magnet motors (PMSM) and can be adapted to the mainstream motor types of high-speed hair dryers on the market, allowing for rapid transplantation without significant hardware adjustments.
