The core of the project is a brushless DC motor originally intended a hydrofoil which is capable of providing 11 pounds (about 5 kg) of thrust. [Braden] has integrated it into a 3D-printed fin ...

Understanding the Structure of Brushless DC Motors ...

Field-Oriented Control is a BLDC motor control scheme that involves using a microprocessor to control the stator winding current in such a way that it always applies torque to the rotor.

Using a small brushed DC motor together with a larger BLDC motor can provide strong acceleration combined with good high rpm power. The brushed DC motor provides initial torque to get the bike ...
