Dynamic motor coil control method

A motor control device for controlling a motor comprising a rotor and a stator, the stator comprising a plurality of coils which are isolated from each other comprising:

• a current controller configured for applying a sinusoidal current to every motor coil, wherein the sinusoidal current is dynamically adjustable;
• a feedback module configured for obtaining an electrical parameter for each motor coil, wherein for each motor coil the electrical parameter is an average voltage over the coil or an instantaneous voltage over the coil;
• a control module configured for executing a feedback-based vector control algorithm that receives the electrical parameter and the applied sinusoidal current for each motor coil to calculate a target current vector based on the electrical parameter and the applied sinusoidal current for each motor coil, and for dynamically adjusting for each motor coil the sinusoidal current applied to that motor coil based on the target current vector.
