  • Patent number: 10273736
    Abstract: The invention relates to a braking mechanism (10) for a movable door wing (1) with an electric motor (14) operating as a generator, the at least one drive shaft of which can be rotated by a movement of the door wing (1), and at the terminals thereof, a movement-dependent output voltage is produced, which is applied to an evaluation and control unit (20), and a stop spring (12) which damps a manual opening movement of the door wing (1) between a predetermined opening angle and a maximum opening angle with a constant first damping, and a corresponding door with a braking mechanism of this type. In accordance with to the invention, the evaluation and control unit (20) performs a pulse width modulation (PWM) of the motor current cooperating with the output voltage and establishes an effective sequence of braking force, which generates a variable second damping of the opening movement of the door wing (1), so that the door wing (1), when released, stops upon reaching the maximum opening angle.

  • Patent number: 10060171
    Abstract: In a power window apparatus, when a controller determines that a captured foreign object, which is captured between a window glass and a window frame of a door, is present, the controller executes an interrupting process that interrupts a current operation of a drive mechanism. The controller does not determine whether the captured foreign object is present in an initial mask period that is a time period from a time point of starting rotation of the electric motor to a time point, at which a rotational speed of the electric motor reaches a stable state. The initial mask period is variable based on an operational load of the electric motor.

  • Patent number: 8963458
    Abstract: The electric tool is powered by a secondary battery as a power source, and includes: an output section configured to be transmitted thereto a rotation of a motor directly or through a decelerator; a voltage measurement section that measures a battery voltage; a storage means that stores, as a reference voltage, a voltage value of the battery voltage measured preliminarily when a motor-lock is occurring; and a control means that controls a driving of the motor. The control means is configured to decide that the motor is being locked and then stop or decelerate the motor upon detecting that the battery voltage measured through the voltage measurement section is maintained lower than or equal to the reference voltage stored in the storage means for a predetermined period of time during the driving of the motor.

  • Patent number: 8957608
    Abstract: A motor-driving device of an electric caulking gun has a micro-controller unit (MCU), a direction-changing module, a motor and a speed sensor. The direction-changing module and the speed sensor are electrically connected to the MCU. The direction-changing module is electrically connected to the motor, and the speed sensor detects a speed of the motor. The MCU is built in with a speed determination procedure comparing an actual speed of the motor acquired from the speed sensor with a preset speed. If the actual speed is lower than the preset speed, it indicates that the resistance at a tube nozzle of the electrical caulking gun increases and the direction-changing module increases the speed of the motor to maintain a preset caulk discharge rate. Given the motor-driving device, the operational inconvenience arising from the unstable caulk discharge rate of conventional electric caulking gun can be tackled.

  • Patent number: 8941343
    Abstract: A control circuit (1) for an electronically commutated, direct current motor (M) without a collector with a semiconductor end stage (2) which is controlled by an electronic commutation control (4) via a driver stage (6) for the time-offset control of the stator coils (U,V,W) of the motor (M) for the purpose of producing a magnetic rotating field for a rotor depending on the rotor rotation position. Two redundant stall protection units (10, 12) monitor the motor (M) during operation for rotation of the rotor, whereby in the case of a determined stall situation, the first stall protection unit (10) deactivates the driver stage (6) and the second stall protection unit (12) shuts off the supply voltage (UVCC) for the driver stage (6).

  • Patent number: 8896258
    Abstract: A method for starting an electric motor having a rotor, comprising the following steps:—driving the rotor with a first torque in a first rotational direction, wherein a maximum value of the first torque is not higher than a maximum countertorque acting counter to the rotation of the rotor, so that the rotor comes to a standstill in a first stationary position;—driving the rotor starting from the first stationary position in a second rotational direction that is counter to the first rotational direction until the rotor comes to a standstill in a predefined second stationary position; and—starting from the rotor in the first rotational direction starting from the second stationary position.

  • Patent number: 8860340
    Abstract: The present invention is provided to remove dust that adhered to a cooling fan. A plurality of comparators are disposed for each of a plurality of coils, respectively, and generates a back electromotive force sensing signal denoting a comparison result by comparing a back electromotive force appearing at one end of each corresponding coil with a neutral-point voltage of the coils. A driving signal synthesis circuit generates a driving control signal used to enable the fan motor to proceed the following actions: (i) enabling the fan motor to rotate toward the opposite direction as a normal operation within a specific reverse rotation period after a driving of the fan motor is started, (ii) applying a brake to the fan motor within a braking period, and (iii) enabling the fan motor to rotate toward a direction of normal operation in a normal driving period. A driving circuit drives the fan motor.

  • Patent number: 8786236
    Abstract: A load control system provides for automatically controlling a position of a motorized window treatment to control the amount of sunlight entering a space of a building through a window located in a façade of the building in order to control a sunlight penetration distance within the space and minimize occupant distractions. The load control system automatically generates a timeclock schedule having a number of timeclock events for controlling the position of the motorized window treatment during the present day. A user is able to select a desired maximum sunlight penetration distance for the space and a minimum time period that may occur between any two consecutive timeclock events. In addition, a maximum number of movements that may occur during the timeclock schedule may also be entered. The load control system uses these inputs to determine event times and corresponding positions of the motorized window treatment for each timeclock event of the timeclock schedule.
