All-Purpose Rechargeable Table Fan Design

@tshibsamuel477

Hi there, I read your offer carefully and understand that you need a complete convertible AC/DC BLDC fan design, including the mechanical enclosure, vibration-resistant truck/tractor mounting system, LiFePO4 battery compartment, universal power electronics, motor control, USB QC 3.0, PCB files, BOM, and STEP models. My background in mechatronics, embedded electronics, power systems, PCB design, motor control, and mechanical product development is well suited to this project. I can support the complete architecture, 3D CAD design, SMPS/DC power stages, LiFePO4 protection and charging, BLDC speed control, automotive surge protection, and production-ready documentation. Just send me a message and we can discuss the specifications, timeline, and project cost. Best regards, Samuel Tshibangu

Hi, I can design your all-purpose rechargeable AC/DC table fan, including the mechanical 3D CAD model, battery base, truck/tractor clamp concept, BLDC motor integration, smart PCBA architecture, Gerbers, BOM, and manufacturing-ready documentation. The best solution is to first confirm the fan size, airflow target, enclosure style, battery connector, motor supplier, vibration requirements, and safety limits. I’ll then design the 12.8V LiFePO4 battery compartment, detachable heavy-duty bracket, BLDC motor mounting, AC/DC power board, BMS logic, surge protection, speed-control interface, and USB QC charging section. I’m comfortable with embedded electronics, BLDC motor control, LiFePO4 charging/BMS design, SMPS-based AC/DC input, wide DC input protection, automotive surge protection, PCB layout, 3D CAD product design, thermal planning, and prototype documentation. Deliverables will include: * 3D CAD model in STEP * Table fan and clamp/bracket design * Battery compartment for 140×70×75mm pack * Smart PCBA schematic and layout * Gerber RS-274X files * BOM with part numbers * BLDC control and speed logic notes * BMS and protection design * USB QC charging section * Manufacturing and assembly notes I’ll focus on a practical, safe, vibration-resistant, and manufacturable design suitable for Indian truck, tractor, solar, AC, and battery-powered usage. Best regards Ankit

Dear Client, I would be pleased to assist with the complete design and development of your All-in-One Convertible AC/DC Rechargeable Fan. I have experience in product design, 3D CAD modeling, PCB layout, embedded electronics, and manufacturing-ready design, enabling me to deliver an integrated solution from concept to production. I can develop the mechanical assembly with the detachable heavy-duty mounting bracket, battery compartment optimized for your 12.8V LiFePO4 pack, and manufacturing-ready 3D CAD (.STEP) files. I will also design the universal AC/DC PCB with Gerber (RS-274X), BOM, BLDC control logic, battery charging/protection, automotive surge protection, multi-speed control, and QC 3.0 USB output while considering reliability and ease of assembly. I am committed to delivering high-quality work, maintaining clear communication, and meeting project deadlines. I would be happy to discuss the timeline, budget, and technical details to ensure the final product meets all your specifications. I look forward to the opportunity to work with you.

Hi there, As a Hardware Design Engineer with EV and automotive experience, I can develop your custom Convertible AC/DC Fan. My expertise in designing embedded systems for high-vibration, variable-voltage environments perfectly matches your commercial truck and tractor requirements. Here is how I will address your key needs: Universal PCBA: Using Altium/Allegro, I'll design a reliable dual-input architecture (SMPS for 90-350V AC, step-down for 10-50V DC) with automotive-grade TVS surge protection to handle alternators and solar panels. Logic & BMS: I'll implement STM32 logic for the 4-speed mapping and to maintain constant speed down to 10V. I will integrate a dedicated BMS for your 12.8V LiFePO4 battery to strictly enforce the 14.6V charging and 10V discharge cut-offs. Mechanical & CAD: I will deliver a highly stable 3D CAD model (.STEP) featuring the heavy-duty detachable clamp and the precise 140x70x75mm hollow base to securely lock your battery pack. Motor & Extras: I'll include drive circuitry for the 30-35W BLDC motor and the QC 3.0 fast-charging USB port. I will deliver the complete 3D CAD, PCB Gerber Files (RS-274X), and BOM. I’d love to jump on a quick chat to discuss the fan blade diameter, airflow targets, and potential motor suppliers you mentioned on the board. Looking forward to collaborating,

Hi there, nice to meet you. Your convertible AC/DC fan project is a strong match for my experience in BLDC motor control, power electronics, battery systems, embedded firmware, PCB design, and mechanical product integration. I can develop the complete system from electrical architecture and production-ready PCB through enclosure, mounting bracket, battery compartment, and manufacturing documentation. I would design a universal power architecture supporting 90–350 V AC through an isolated SMPS and 10–50 V DC through protected wide-input conversion. The control system will maintain constant motor speed using closed-loop RPM feedback, provide four selectable speed levels, manage the 12.8 V LiFePO4 battery safely, and protect against alternator and solar-input surges. A realistic development timeline is approximately 8–12 weeks, depending on motor customization, prototype availability, and mechanical revisions. I can provide a detailed milestone-based quotation after reviewing the required fan diameter, airflow target, enclosure limits, certification requirements, and prototype quantity.

Hi, I'm a final-year Mechanical Engineering student specializing in embedded systems and control systems, with hands-on experience building hardware from concept to prototype — including HelioFrame, a dual-axis solar tracker (ESP32, LDR sensors, servo actuation), plus formal industrial training (SIWES) in embedded systems. How I'd approach this project: Mechanical Design & CAD (my core strength): Full 2-in-1 convertible design — table fan form factor plus a heavy-duty detachable bracket built for high-vibration truck/tractor mounting. Battery compartment sized exactly to your 12.8V 12Ah LiFePO4 pack (140x70x75mm), motor housing for the specified BLDC shaft, delivered as manufacturing-ready .STEP files. Motor & Control Logic: DC 12V motor integration, control logic, and BOM sourcing support for the 30-35W BLDC motor per your specs. Power Electronics (PCBA/SMPS):For the AC-input stage (90V-350V) and PCB Gerbers, I'll bring in a power electronics specialist for this portion — safety-critical AC design deserves someone with deep, dedicated experience, so your product is genuinely safe and manufacturable, not just functional on a bench. Happy to discuss timeline and whether you'd prefer combined or phased (mechanical first, then PCBA) delivery. I can share CAD and embedded work samples on request. Looking forward to hearing from you.
