Latest Patents
Saeid holds a patent for "Brushless motor control circuitry with optimum current vector control." This invention describes a drive circuit for a brushless motor that utilizes both phase shift and current shaping. The design aims to provide efficient operation of a brushless motor within a servo control system. The circuit includes features for altering the phase of the drive signal based on motor velocity. This adjustment compensates for increased current phase lag due to the motor's inductance at high commutation frequencies. Additionally, the circuitry modifies the commutation signal waveform to address a non-sinusoidal field distribution, producing nearly sinusoidal torque from each of the motor windings. The compensation for both phase shift and waveform is achieved using digital circuitry, with phase commutation being a non-linear function of motor velocity.
