Latest Patents

Erik M Obel holds one patent titled "Method and device for controlling a brushless alternating current motor." This invention involves a method and device for controlling a brushless alternating current motor driven by an inverter connected to a direct current supply. The direct current supplied to the inverter is sensed, and the signal is passed through a peak detector to a regulator. The regulator decreases its frequency controlling output signal if the peak value input signal exceeds a predetermined value. Additionally, a control signal corresponding to the torque demand of the motor is produced, which controls the voltage supplied to the motor. Negative pulses at the turning off of the inverter switches are also sensed and used for controlling the degree of magnetization of the motor.
