README

Overview
Easy BLDC is an open source sensorless FOC brushless dc motor driver designed for propeller thrust applications such as drones or underwater AUVS.
Features
- 30V Maximum Input Voltage
- 20A Maximum Continues Current (Untested)
- High current Amphenol power blade connector for board-board mounting
- High efficency FOC algorithm
- Modifiable parameters via Ti MotorWare® GUI
Why FOC?
FOC is the most advanced of the three common algorithms. Unlike trapezoidal or sinusoidal control, which energize the motor’s phases based on predefined waveforms, FOC actively keeps tracks the stator position. This allows for precise control of both torque and speed by decoupling the motor’s magnetic field into two components: one that controls the motor's flux and the other that controls the torque. FOC is extremely efficient, especially at higher speeds, and results in smooth operation at lower speeds.
