DC Motor Control Circuit Prototype
Budget: ₹1,500 – ₹12,500 INR
I’m building an industrial‐grade DC motor controller and need a complete electronics solution that goes from schematic to a fully tested, working prototype I can drop straight into my test rig.
Scope of work
• Design a robust control circuit that can drive a DC motor reliably in an industrial environment, taking into account noise immunity, thermal protection and fault handling.
• Produce a clean schematic and a production-ready PCB layout.
• Select all components with realistic lead times and provide a detailed BOM.
• Assemble, program (if a microcontroller or gate driver IC is used) and bench-test the prototype, then ship it to me ready for integration.
• Supply all design files (GERBERs, CAD source, firmware, test results) so I can replicate or scale production later.
Acceptance criteria
The prototype must:
1. Vary motor speed smoothly from 0 % to 100 % under a 24 V DC supply.
2. Deliver at least 10 A continuous with over-current and over-temperature protection kicking in gracefully.
3. Maintain speed within ±3 % under a 20 % load swing.
4. Pass a 12-hour burn-in at 40 °C without thermal shutdown.
Please outline which CAD and simulation tools you prefer (Altium, KiCad, Eagle, LTspice, etc.), the control strategy you intend to use (PWM with MOSFET H-bridge, dedicated driver IC, micro-based PID, or another proven approach), and your typical lead time for prototype assembly. I’m ready to move quickly once we lock in the design path.
