ZhuhaiJune 9, 2026 /PRNewswire/ — In recent years, with the upgrading of hair care consumption demands, high-speed hair dryers have become a popular category in the personal care appliance sector, thanks to their features such as low-temperature quick drying and excellent hair care effects. These products rely on high-speed brushless motors with over 100,000 revolutions per minute, using strong airflow to replace traditional high-temperature blowing, thereby reducing heat damage to hair. At the same time, they are equipped with an ionizer function to make hair smoother and shinier.
Application Challenges of High-Speed Hair Dryers:
- High computational demands: Driving a motor with an electrical frequency of up to 1.83 kHz requires an extremely short control cycle, which imposes higher demands on the MCU’s computing power and real-time performance;
- Significant device losses: High-frequency switching increases power device losses and exacerbates temperature rise, requiring devices to balance high performance with low losses;
- Rotor angle deviation: Under high-speed operation, the rotor position offset during the interval between sampling and waveform generation is large, which can easily reduce control efficiency;
- High temperature control difficulty: The conduction angle of the thyristor and the heating power are nonlinear, making it difficult for conventional temperature control algorithms to balance accuracy and response speed.
Geehy, keeping pace with industry demands, has launched the G32F031 high-speed ionizer hair dryer control reference solution. This solution can specifically address the application challenges currently faced by high-speed hair dryers. While achieving an operating speed of 11Wrpm, it supports multi-level airflow/temperature adjustment, intelligent constant temperature, ionizer hair care, and multiple protection functions, helping customers achieve low-cost, high-efficiency development and mass production, and comprehensively enhancing the user experience.
Introduction to the G32F031 High-Speed Hair Dryer Reference Solution
Core Advantages of the Solution
- Utilizes Geehy’s G32F031 next-generation motor control MCU, capable of stably controlling a motor with an electrical frequency of 1.83 kHz at a high carrier frequency of 20 kHz;
- Paired with the GHP500N05 low-power intelligent power module (IPM), ensuring the chip temperature rise remains within normal range even at a 20 kHz carrier frequency;
- Enhances rotor position observation accuracy through an angle compensation function, thereby effectively improving motor operating efficiency;
- Introduces an incremental variable-gain PI control strategy, strengthening the integral action in the low conduction angle range for rapid heating, and weakening the integral action in the high conduction angle range to suppress overshoot, thus achieving superior temperature control quality across the full temperature range.
