Hi, I am an embedded systems engineer with over 16 years of experience developing electromechanical and consumer products from concept through prototyping and production. I can design and fabricate the three compact electromagnets, including the two curved units, with coil geometry, core material, thermal limits, mounting, and an adjustable current/PWM driver developed as one integrated system. My approach would be to model the magnetic circuit around your final envelope, build and characterize the coils, then tune the driver for stable continuous operation. I will test pull force at minimum, midpoint, and maximum settings and provide the coil data, CAD, schematic, wiring instructions, and measured results needed for reproduction. The key detail to confirm is the working air gap and mating material/pole-face arrangement, since these largely determine whether 40 N is achievable within the narrow footprint. Could you also provide the diagram and final arm/sphere geometry, including mounting locations? I would be glad to discuss the mechanical constraints, fabrication options, and shipping arrangements with you.

Hello, I’m an experienced mechanical/electromechanical engineer with hands-on experience in electromagnetic actuators, coil design, motor control, thermal considerations, CAD and prototype development. Your project is a good fit for my background. I can develop the three electromagnets from the magnetic and mechanical requirements through fabrication and testing, including the two curved units and the straight unit integrated through the spherical assembly. My approach would include: Magnetic/core material and geometry selection Coil turns, wire gauge, resistance and current calculation Design for up to 40 N adjustable holding force 12–24 V DC operation with PWM/current control Thermal analysis for continuous operation Mechanical CAD and mounting/interface design Driver/control circuit and wiring diagram Fabrication and assembly of all three units Pull-force testing at minimum, mid and maximum settings CAD, coil specifications and schematic documentation for future reproduction I would specifically optimise the design around the very constrained 1–3 × 100 × 10 mm envelope, because achieving 40 N while maintaining acceptable temperature will require careful optimisation of the magnetic circuit and coil. I can also recommend an alternative magnetic/actuation architecture if it provides better force-to-size ratio or thermal performance. I’m ready to review the attached diagram and final dimensions and provide a detailed design, cost and timeline. Best regards,

Hi, I am a senior electronics/mechatronics engineer with experience designing custom electromagnets, DC coil drivers, PWM/current-control systems, and compact electromechanical assemblies, including prototypes validated to 40+ N pull force and continuous-duty thermal limits. Approach ✅ I will calculate the magnetic circuit, core geometry, turns, wire gauge, resistance, and current required to achieve up to 40 N within the 12–24 V envelope. ✅ I will design the three coil assemblies for the curved and straight geometries, optimizing winding density, mounting interfaces, insulation, and continuous-duty thermal performance. ✅ I will develop a compact PWM/current-limited driver with adjustable force control and protection against overcurrent and thermal stress. ✅ I will fabricate and characterize all three units, measuring pull force at minimum, mid-range, and maximum settings, then deliver CAD, coil data, schematic, wiring, and test results. Questions ✅ What are the exact final envelope dimensions, curved radii, and available mounting/clearance around each 1–3 × 100 × 10 mm core? ✅ Is the required 40 N force measured against a flat ferromagnetic target, and what are the required air gap and target material? ✅ What is the expected continuous operating duty cycle and maximum acceptable surface temperature?

@miguelcen64

Hello, The key part of this project is **designing three compact electromagnets that fit a tight harness footprint while delivering up to 40 N without overheating or drifting**. I can help you handle this accurately and efficiently without overcomplicating the process. I have hands-on experience with **Electronics, Electrical Engineering, and PCB Layout**, including practical documentation for buildable hardware. For your project, I would focus on coil sizing and winding geometry, driver/current control for stable force tuning, and the mechanical packaging details needed for the curved and straight units, while making sure the final result is reliable and reproducible. I can start immediately and expect to complete this within 21 days. One detail I'd like to confirm before starting: **what is the available duty cycle or continuous-on time at maximum force, and is there a target coil temperature limit? What is the available duty cycle or continuous-on time at maximum force, and is there a target coil temperature limit?** Best regards, Miguel

@alluankit01

Hi, I can help design, fabricate and test the three custom DC-controlled electromagnets for your prototype, including two curved units and one straight unit based on the final dimensions and diagram. My approach will be to first review the available footprint, core shape, mounting constraints, required 12–24V supply, holding-force target and thermal limits. Then I’ll define the core material, winding data, wire gauge, coil turns, driver/control method and test procedure. I can help with: * Custom electromagnet design * Curved and straight core planning * 12–24V DC operation * PWM/current-limit control * Holding force adjustment up to 40N * Coil winding specifications * Thermal review * Mounting-point design * Driver wiring diagram * Test documentation Deliverables: * 3 assembled electromagnets * Matching control interface * Wiring diagram * Basic operating instructions * Pull-force test report at min/mid/max settings * Coil data * CAD/source files * Circuit schematic I’ll focus on compact size, stable holding force, safe continuous operation and clear documentation so the magnets can be reproduced or modified later. Best regards Ankit

@ahmaddar2970

Thanks for the detailed brief. I can fabricate three compact DC-controlled electromagnets to your footprint, including the two curved units and the straight center-through-sphere unit, with integrated mounting features and a matching control interface. I’ll design around a 12-24 V DC input, target the 40 N ceiling, and prioritize continuous operation with managed thermal performance and stable holding force. I can provide the full package you outlined: assembled electromagnets, driver/control wiring, a simple operating guide, pull-force test results at minimum/mid/max settings, and source files for the coil data, CAD, and circuit schematic. If the final dimensions and interface constraints are provided up front, I can optimize the winding approach and core material for reliability and fit. For production, I’d recommend settling the final envelope and mounting geometry first, then I can propose the most practical coil geometry and control method to reduce heat and simplify assembly. Ready to proceed once the final dimensions and attachment details are shared.

Thermal performance will also be considered for continuous operation, with current limiting and PWM control used to provide repeatable force adjustment while avoiding excessive heating or magnetic drift.

@GridsmithLTD

Hello, I reviewed the requirements and the main challenge is fitting three compact electromagnets into a constrained harness while achieving the required variable force without excessive heat or magnetic drift. I would develop the coil, core, winding, and driver arrangement around the available footprint, with separate consideration for the two curved units and the straight magnet passing through the sphere. I have experience with electromechanical product development and compact prototype systems and can share relevant examples once we connect in chat.
