Details Introduction
DC Brushless Blower Control Module
Sounds Electric's DC brushless blower control module integrates FOC vector control with intelligent pressure-tracking technology, redefining energy efficiency and noise control standards for blower equipment. The control module supports stepless speed adjustment from 800–1500 RPM with 1% speed precision, improves pressure stability by 40%, reduces energy consumption by 35%, and ensures industrial-grade quiet operation with long-term reliable performance.
▌Core Technology ：
• Intelligent Variable-Frequency Drive: Features sensorless sinusoidal control to drive a three-phase motor, with real-time magnetic field angle calculation. Torque ripple is kept below 5%, supporting both forward and reverse motor startup.
• Full Digital DSP Control: Powered by a 32-bit digital signal processor (DSP), enabling millisecond-level dynamic response, adaptive load regulation, and intelligent air-pressure compensation.
•Comprehensive Protection System: Integrates overcurrent, overvoltage, overtemperature, and phase-loss protection, extending IPM module lifespan by up to 50%.
•Wide Input Voltage Range: Supports 90–264 VAC input for stable operation under complex power grid conditions.
•Ultra-Quiet Technology: Carrier frequency modulation and mechanical resonance suppression algorithms reduce operating noise to ≤45 dB at 1 meter.
▌Industrial Design Advantages
•Wide Performance Coverage: Compatible with 170V / 310V DC brushless DC motor platforms, supporting a power range of 30W–120W.
•Advanced Thermal Design: Thickened copper layers and optimized thermal paths ensure a full-load temperature rise of ≤35°C, supporting stable continuous operation.
•Simplified Integration Design: On-board terminals enable plug-and-play installation, supporting multiple speed level switching and wiring harness configurations.
Q1: What should we provide to get a quotation and samples?
A: Please send us the Gerber files and BOM list. You are also welcome to provide any physical samples if available. Kindly include detailed project information. If testing is required, please specify the testing standards.
Q2: Can you provide samples?
A: Yes, we can. We always produce new samples for customers to verify the quality. Samples help confirm the design and ensure everything is ready for mass production.
Q3: Can you offer a better price?
A: Yes. We are a professional manufacturer with over 30 years of experience. With a strong supply chain and production capability, we can offer competitive pricing, often better than trading companies.
Q4: What is the estimated lead time after placing an order?
A: For samples, the lead time is usually 10–15 days. For bulk production, it is typically 15–20 days. The final timeline depends on the product design and requirements.
Q5: What shipping methods do you use?
A: Samples are usually shipped via DHL, UPS, or FedEx. For bulk orders, we offer both air and sea freight. If you have a preferred shipping method, please let us know.
Q6: Can I visit your factory?
A: Yes, you are very welcome to visit our factory. During your visit, we will show you our production facilities and manufacturing process. Please feel free to contact us to schedule an appointment.
