  • Patent number: 11795952
    Abstract: An electric pump includes a pump, a motor configured to drive the pump, a motor drive unit having a switching element and configured to drive the motor with electric power output from the switching element, and a control unit configured to output a pulse width modulation (PWM) signal for driving the switching element to the motor drive unit. The PWM signal output from the control unit, is used for monitoring a state of the motor. When the motor stops abnormally, the control unit sets a frequency of the PWM signal for use in monitoring the state of the motor to a frequency outside of a frequency band which is used when the motor is normal.

  • Patent number: 11799405
    Abstract: In sensorless control for a rotary machine, when variations in inductances for U, V, W phases due to manufacturing error are great, imbalance occurs among detected currents for the respective phases. Thus, estimation error of a magnetic pole position of a rotor increases, so that positioning accuracy is reduced. Correction filters for imparting gains in accordance with rotary machine constants for the respective phases are provided to control means or magnetic pole position calculation means, thereby correcting the imbalance occurring among the detected currents for the respective phases.
