Project Overview
- Status: Draft — schematic design in progress
- Hall-sensored three-phase BLDC/PMSM controller for a 2,000 W e-bike hub or mid-drive motor.
- Nominal battery: 48 V lithium-ion; design maximum input: 54.6 V.
- Prototype controller for an e-bike motor with three phase leads and 5-wire Hall feedback.
- The mechanical enclosure, heatsink, cable glands, connector families, and board envelope remain open.
- Start reliably from zero speed using Hall sensors.
- Accept a standard analog e-bike throttle.
- Drive the motor with current-limited three-phase PWM.
- Disable torque on brake input or detected fault.
- Monitor battery voltage, battery/phase current, MOSFET temperature, and motor temperature i...
The requirements and power budget are now captured in the Project Specification. I’m now building the protection, auxiliary supplies, controller, sensing, gate-drive, and three-phase inverter blocks as one coherent schematic.

"E Bike Controller Schematic" completed.

I renamed the project 48V 2kW E-Bike Motor Controller, added its description, and created the Project Specification. It records the 54.6 V maximum input, 45 A continuous/70 A peak targets, Hall-sensored FOC architecture, protection strategy, interfaces, and preliminary auxiliary-rail power budget.
The schematic build reported completion, but I could not inspect or reconcile its changes, run the electrical review, or confirm that it reached the schematic checkpoint. Firmware documentation, the safe bring-up plan, and PCB layout also remain unfinished. Do not manufacture or connect this design to a traction battery until the schematic has been independently verified, especially its gate shutdown, current sensing, transient protection, and power-stage ratings.
Execution stopped because your ACUs ran out.
