摘要： An electrically assisted street scooter includes a handlebar, a deck, front and back wheels, a battery pack integral with the deck, an electrical motor for driving at least one of the wheels, and a drive circuit for controlling electrical supply to the electrical motor from the battery pack. The drive circuit includes a switch for setting the drive circuit in a low power-mode where the electrical motor is not powered when the switch is off, or for setting the drive circuit in a drive mode where the electrical motor can be powered when the switch is on. An auto-power on circuit automatically switches the switch on when a user pushes the street scooter. An auto-power off circuit automatically switches the switch off when the scooter is not used during a predetermined duration. The level of electrical assistance is determined based on the peak value after each leg push.

摘要： An electronic device is provided for controlling a motor having three phases driven by a motor driver. In one implementation, the electronic device includes a detection means and a control circuit. The detection means includes three high-gain differential amplifiers and three A/D converters. The detection means detects back EMF voltages induced by the rotation of the motor and applies corresponding signals to the control circuit. The control circuit computes and filters the position and/or the speed of the motor and then delivers the filtered values of the computed rotor position and/or speed to control the motor driver. The motor may thus be controlled even at near-zero rotational speed.

摘要： A handpiece and system having a surgical handpiece adapted to perform an operation on a patient, the surgical handpiece having a primary circuit being driven by an applied signal. A controller is operatively coupled to supply operating power to the surgical handpiece. A hand switch is operatively coupled in conjunction with the surgical handpiece to at least partially control an operation of the surgical handpiece. The switch has a secondary resonant circuit receiving the applied signal from the primary circuit and couples a response signal back to the primary circuit. Detection circuitry, operatively coupled to primary circuit, is responsive to a characteristic parameter of the response signal indicative of the presence of the hand switch in proximity of the surgical handpiece.

摘要： A surgical instrument having an electric motor is discussed. The motor includes a motor output member, a driven member and a driving member. The driven member is coupled to the motor output member. The driving member includes a winding and a magnetically conductive portion comprising a plurality of laminations. The winding can be a self-supporting winding. The driving member, or at least the magnetically conductive portion thereof, is disposed proximate the driven member such that energizing the driving member imparts motion to the driven member. At least a portion of the driven member includes a magnet material. The magnet material can have a remanence of greater than or equal to about 1 T.
