Latest Patents

One of his latest patents is titled "Optimized regenerative braking control of electric motors using look-up tables." This invention involves a regenerative braking controller designed for AC motors. The controller determines the electromagnetic torque necessary for slowing or stopping the motor by accessing a lookup table. This table retrieves a braking torque value that corresponds to the current estimate of rotor velocity. The retrieved braking torque can represent either a maximum or minimum torque level for regenerative braking at the current rotor velocity or a torque level that maximizes charging current during regenerative braking. Additionally, if an external mechanical brake is present, the regenerative braking controller can send an external braking torque signal to a controller, allowing the mechanical brake to apply the remaining braking force beyond what is indicated by the regenerative braking torque. The patent also discloses a method for establishing the braking torques to be stored in the lookup table.
