Brushless Motor Hardware & Firmware Design Service 110V/220V 50W

Custom hardware and firmware design for small brushless DC (BLDC) motors with Hall-effect position sensors. Suitable for appliances, fans, pumps, small power tools and other consumer or industrial products.

Specifications

• Input voltage: 110V / 220V AC (rectified DC bus); DC-supply variants available
• Motor type: Brushless DC (BLDC) with Hall sensors — 6-step trapezoidal commutation or sensored FOC
• Power range: up to 50W
• Speed range: configurable (target RPM set by customer)
• Control interface: PWM / analog speed reference / UART; optional closed-loop PI speed control
• Protection: over-current, over-voltage, under-voltage, locked-rotor, thermal, soft-start

Deliverables

• Schematic (Altium / KiCad / Eagle)
• PCB layout (2- or 4-layer, depending on EMI and thermal requirements)
• BOM with cost-down alternatives
• Gerber files ready for fabrication
• Firmware source code (C, GCC / IAR / Keil) plus prebuilt binary
• Test plan and bench-test report

Design Fee & Lead Time

• Design fee: USD 500 – 800 (depending on complexity and certification target)
• Lead time: 5 – 10 weeks (schematic, layout, prototype bring-up, firmware)
