摘要： A variable frequency motor drive comprises a converter including a rectifier having an input for connection to an AC power source and converting the AC power to DC power. A DC bus is connected to the rectifier circuit. At least one bus capacitor is across the DC bus. An inverter receives DC power from the DC bus and converts the DC power to AC power to drive a motor. A controller is operatively connected to the converter. The controller comprises a speed control controlling the inverter responsive to a speed command to maintain a desired motor speed. A speed foldback control measures DC bus ripple voltage and regulates the speed command responsive to the measured DC bus ripple voltage.

摘要： A door opening/closing control device includes: a controller controlling driving of an actuator opening or closing a door; a position detector detecting an opening/closing position of the door; a speed calculator calculating an opening/closing speed of the door based on a temporal change in the opening/closing position detected by the position detector; and a target assisting force calculator calculating target assisting force based on the opening/closing position and the opening/closing speed of the door. The controller controls the driving of the actuator to assist an operation of opening or closing the door based on the target assisting force calculated by the target assisting force calculator. Further, the controller controls the driving of the actuator such that the door is fully closed upon judgment that the opening/closing position of the door is in the vicinity of the fully closed position based on the opening/closing position detected by the position detector.

摘要： A product dispenser includes a product housing including a drive system and a dispensing apparatus. The drive system includes a motive power device and a controller and is configured to receive energy from an energy supply. The dispensing apparatus is configured to dispense the product. During a condition when the product is being dispensed, the dispensing apparatus is subject to a dispensing resistance and the drive system provides an output to the dispensing apparatus to overcome the dispensing resistance, the output being characterized by a dispensing parameter. The controller receives the dispensing parameter and responsively operates the motive power device, such that the controller operates the motive power device in a first output drive condition in response to the dispensing parameter being below a threshold value, and operates the motive power device in a second output drive condition in response to the dispensing parameter being above a threshold value.
