Latest Patents

One of Andrea's latest patents is titled "Low acoustic noise open loop motor startup." This invention involves methods and apparatus for motor startup with reduced acoustic noise. It includes a startup module that generates a startup d-axis voltage and a startup q-axis voltage during a startup interval. The startup interval concludes based on the observer error, and the q-axis voltage increases throughout this interval. The module is designed to continuously and linearly increase the motor's speed during startup. An observer generates estimates for speed and angle, along with an observer error that represents the difference between the actual angle and the estimated angle. The voltage increment for the q-axis voltage is adjusted according to the observer error, ensuring optimal performance.

Another significant patent is "Motor controller having low noise high frequency signal injection." This invention outlines methods and apparatus for motor control that utilize low noise variable-high frequency signal injection for electric motors. It involves selecting different injection signals on a cycle-by-cycle basis to control the motor effectively. The characteristics of these signals are configured to minimize the acoustic noise generated by the motor.
