I’m ready to hand over the full schematic of my 36 V / 500 W brushed-motor controller so you can put it under the microscope. The design is built around three power-side MOSFETs driven by a four-comparator PWM stage, and it also ties into a throttle, a 36 V battery pack, and a basic lighting circuit. Your brief is to confirm that every part of the schematic is electronically sound, that the gate-drive and comparator timing will let the MOSFETs switch cleanly at load, and that the surrounding devices (throttle hall sensor, battery protection, head- and tail-lights) remain within safe operating limits in all modes. Along the way, flag any weak points—trace width, thermal bottlenecks, wrong footprints, missing fly-back paths, logic-level mis-matches—and propose fixes directly in the design file. I work in Autodesk EAGLE, so I’ll send you the .sch file; please return the updated version in the same format. If you prefer to prototype a section in LTspice or a similar simulator to justify changes, feel free to do so and include the plots in your hand-over notes. I’ll also need a clean, purchase-ready bill of materials. A simple spreadsheet with manufacturer part numbers, supplier SKUs, voltage/current ratings, package, and pricing columns is perfect. Focus on parts that are immediately available through the usual channels (Digi-Key, Mouser, LCSC, etc.) so I can hit the ground running once the design is signed off. Deliverables: • Revised EAGLE schematic/board files with all corrections applied • Simulation or calculation notes that prove the circuit will drive 36 V @ 500 W continuously without thermal or electrical overstress • Spreadsheet BOM as described above • Short verification report summarising what was checked, what was fixed, and any optional improvements I might consider for a future spin If this scope is clear, let me know your expected turnaround and any questions you might have about the current design constraints.

With my extensive experience in Digital Motor Control, Analog Design, Power Electronics, and Electronic Design, I possess the perfect blend of skills your project demands. I've designed complex circuits like yours before, which required intricate integration of numerous components like MOSFETs, comparators, throttle sensors, battery packs, and lighting circuits. My previous projects have also involved working with Autodesk EAGLE, LTspice simulations alongside similar tasks like providing comprehensive BOMs and design recommendations. To showcase the soundness of your current schematic design and flag potential issues accurately, I'll be relying on my expertise with powerful simulators and calculators like LTspice and Matlab. My ability to deliver verified EAGLE schematic/board files showcasing all necessary corrections while proving the robustness of your design under 36V @ 500W operating conditions is what sets me apart. I have delivered simulation outputs including analysis for thermal and electrical stress levels before for a variety of power electronic applications.

As an electrical engineer and a professional specializing in PCB Layout and Simulation, I believe that I am the perfect fit for your 36V Motor Controller Verification project. Over the years, I have developed a firm grip on design analysis and optimization which will play a crucial role in verifying your schematic design, identifying any weak points, and proposing amendments in a transparent way as you've requested. It's noteworthy that I am well-versed in Autodesk EAGLE - the same format your design is based on making it easy for me to return the updated version. My skill set transcends mere schematic reviews, delving into simulation notes that can underscore the circuit's ability to run efficiently at 36V @ 500W or even more without thermal or electrical overstrain. This process will help us justify various changes if necessary using appropriate plots. Furthermore, I assure you a comprehensive verification report wrapped up with any optional improvements that can uplift the future iterations of your design. Lastly, my ability to analyze complex systems extends into sourcing components. With industry-known suppliers like Digi-Key and Mouser et al., their part numbers, voltage/current ratings, package, and competitive pricing will be skillfully summarized in a purchase-ready Bill of Material intended for an accelerated workflow progression as soon as the design is authorized. Communicate your expected turnaround time and let us get started on validating your design!
