摘要: A method for detecting an obstacle opposing the movement of a screen in a home automation closure or sun protection system includes an electromechanical actuator driving movement of the screen. The electromechanical actuator includes a torque support, a housing, an output shaft, and an electric motor including a stator and a rotor. The system includes a winding shaft rotating the screen and a connecting accessory between the electromechanical actuator's output shaft and the winding shaft. The method includes: determining an angular displacement value of the rotor with respect to the stator; determining angular displacement of the winding shaft relative to the housing or torque support of the electromechanical actuator; determining angular deformation of the kinematic chain between the electric motor and the winding shaft by comparing these two angular displacements; and determining the presence of an obstacle to screen movement from an angular deformation exceeding a predefined value.

摘要: A motor control device at least includes a speed control part for controlling a motor rotation speed. The motor control device includes a torque correction means for suppressing variation in torque constant due to individual differences of motors. In addition, the motor control device corrects the torque constant by using a correction torque coefficient calculated based on an unloaded speed when a fixed voltage is applied. Alternatively, the torque constant is corrected using the correction torque coefficient calculated based on the motor applied voltage when the motor speed is fixed.

摘要: Apparatus featuring a signal processor or signal processing module configured to: receive signaling containing information about a sampled leakage magnetic flux sensed from a motor, a motor load profile containing a learned leakage magnetic flux sensed from the motor and stored during a learning stage, and a user selectable band of tolerance related to the motor load profile to trigger an alarm condition for the motor; and determine corresponding signaling containing information about whether to trigger the alarm condition for the motor if the sampled leakage magnetic flux is outside the user selectable band of tolerance of the motor load profile, based upon the signaling received. The leakage magnetic flux may be sensed by, and/or received from, a motor flux leakage sensor arranged on an external surface of a frame of the motor.

摘要: A method to control the rotor position in a reluctance motor includes: energizing a phase winding to an energized state so as to move a rotor relative to a stator; switching the phase winding between the energized state and a freewheeling state over a pulsing period to produce a plurality of phase current pulses wherein the phase current freewheels in the freewheeling state over a freewheeling period of each current pulse; sampling rates of change of phase current and amplitudes of phase current during a plurality of freewheeling periods; de-energizing the phase winding; and computing the angular position of the rotor.

摘要: A system including an electric motor and a control software operable to control the operation of a plurality of different types of electric motors. The control software is provided with or identifies a particular control algorithm from among a plurality of such algorithms and/or a particular set of operational parameters from among a plurality of such sets for the motor with which it is assembled. The sets of operational parameters are stored in one or more read-only memories, which may be electrically erasable programmable read-only memories. To identify the particular motor control algorithm and/or the particular set of operational parameters, the control software causes the motor to be energized, senses an actual operating parameter of the motor, and identifies the particular motor control algorithm and/or the particular set of operational parameters based on the sensed actual operating parameter.

摘要: A method of determining a position of a rotor of a brushless permanent magnet motor includes measuring a current value indicative of current flowing through a phase winding of the motor and providing a reference voltage value indicative of a voltage applied to the phase winding of the motor. The method includes calculating a phase of back EMF induced in the phase winding using the measured current value and the reference voltage value, and determining a zero-crossing point of the back EMF induced in the phase winding using the calculated phase of back EMF induced in the phase winding. The method includes generating a rotor position signal based on the determined zero-crossing point.

摘要: An improved system and method for tuning a motor controller is disclosed. The improved system and method for tuning a motor controller adjusts controller gains and filter settings in tandem to achieve a desired level of performance. A user terminal is in communication with a motor controller and reads the existing controller gains from the motor controller. The user terminal displays the existing controller gains and at least one user selectable object for adjusting the controller gains. A user adjusts the user selectable object to adjust the controller gains in tandem. The controller gains are adjusted responsive to the user input while maintaining existing relationships between controller gains. The user terminal writes the adjusted values of the gains to the motor controller.
