摘要:
An electric motor (100) for operating a shutter or solar protection element in a building, comprising at least two phases (10; 20, 30; 50, 60) and a magnetized rotor (16; 40; 70) common to both phases, each phase being relative to a rotor portion (41, 42; 71; 72) in the direction of the axis of the rotor and comprising two windings (14, 15), wherein each phase comprises an insulating yoke frame (13) on which the two windings are produced and which has a central portion (131) separating the windings, the central portion being provided with a first through-recess (134) able to surround a rotor portion passing through the phase.

A motor-driven carriage (100) for opening/closing a curtain, includes a housing (110) that is provided with two members (124, 126) for suspending the housing from a rail (50), wherein a friction wheel (112), which is driven by an electric motor and which is to contact at least one rolling surface (56, 57) of the rail, is rotatably mounted inside the housing. The carriage (100) also includes a cradle (150) provided with two other members (155, 156) for suspending the cradle from the rail (50), which are separate from the members (124, 126) for suspending the housing (110), as well as elements (153, 154) for coupling to the curtain. The cradle is mounted onto the housing (110) and is driven by the housing when the latter moves along the rail, the housing (110) and the cradle (150) optionally being capable of relative movement there between.

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:
The invention concerns an electrical machine, whereof the active part includes a global solenoid winding (110, 210, 310) for each phase and includes, inside said winding(s), a stack of ferromagnetic or non-magnetic parts (400) and magnetized parts (500), the ferromagnetic or non-magnetic parts being provided with passages traversed each by at least one relatively sliding element (600), each sliding element constituting a succession of portions alternately magnetic (620) and non-magnetic (630), the passages formed in the ferromagnetic or non-magnetic parts of the stack forming orifices whereof the internal cross-section encloses each time one sliding element, the sliding elements (600) consisting in rods having each an outer periphery matching the internal cross-section of the traversed orifices.
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.
摘要:
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.
摘要:
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.
