A method for operating a motorized solar protection home automation installation, comprising: an actuator intended to unfold and fold up a fabric, comprising a motor and a motor control module, and a panel of photovoltaic cells that is fixed or mobile under the effect of the actuator, intended to supply energy to recharge a reserve of electrical energy powering the actuator, the operating method comprising the following automatic steps: determination of a criterion for recharging the energy reserve, if the criterion is satisfied, displacement of the panel of photovoltaic cells or of the fabric to a recharging position in which the panel is exposed directly or by reflection to the solar rays to recharge the energy reserve.
摘要:
A metal or plastic tube is formed with slots to establish a noise dampening coupling to isolate the head rail of a window covering from vibrations from a motor in the head rail. The noise dampening coupling can be coupled to the output gear of the motor and to an actuator in the head rail to couple the motor to the actuator while isolating the head rail from vibrations. Also, a non-rotatable noise dampening coupling can be interposed between the motor and head rail to further isolate the head rail from vibrations.

A position sensor generates a signal representative of the angular position and, if desired, angular velocity of a rotating object using only a single circular track and plural brushes that ride on the track when the object rotates. The single circular track can have plural segments, and the sensor can generate more than one signal cycle per revolution.

A motor for turning the rod of an object such as a window covering is attached to an elongated ferromagnetic bar. Magnets are closely spaced from the bar, and as the bar rotates to cut the magnetic field lines, pickup coils generate signals that can be used to determine the direction and speed of rotation and also the position of the motor (and, hence, the position of the object being moved). The magnets brake the motor from turning under the weight of the object when the motor is deenergized.

The invention relates to an electric motor having a rotor and a coiled stator, the rotor including a shaft and two disks that are rotatably fixed to the shaft and provided with permanent magnets, a so-called outer portion of the stator extending from each disk axially parallel to a rotational axis of the rotor and radially beyond same, from the axis. The stator includes a plurality of disjointed bars consisting of a magnetically conductive material, certain parts of which form the outer portion of the stator. The stator also has a carrier structure holding the bars such that they are fixed in relation to each other, said carrier structure being mounted in such a way that it can rotate on the shaft, axially outside the two disks. The outer portion of the stator extends parallel to the rotational axis, axially outside the disks of the rotor, up to the carrier structure.

The device (1) comprises a frame (42) comprising a static magnetic pole (48), a movable member (44) relatively to the frame (42), the movable member (44) comprising a moving magnetic pole (46), the static magnetic pole (48) and the moving magnetic pole (46) being magnetically coupled in some position of the movable member (44), a piezosensitive element (50) so that the force due to the magnetic coupling between the moving magnetic pole (46) and the static magnetic pole (48) reacts on the piezosensitive element (50), and means (52, 54, 56, 58) for outputting an electric signal from the piezosensitive element (50), the signal being useful in determining the position and/or the speed and/or the direction of the movable member (44).
摘要:
A bracket includes a rigid member that can be fastened to a fixture such as a wall, and flexible elements depend downwardly from the rigid member and are engaged with a tubular motor assembly of a window covering, awning, projector screen, or the like, to couple the motor assembly to the fixture while attenuating the propagation of vibrations from the tubular motor assembly to the fixture. This reduces noise in the room. The flexible elements may be flexible strings, elastic strings, or coil springs and have horizontal stiffness coefficients much lower than the vertical stiffness coefficient.
