摘要： The mechanism enables torque protection in a brushless motor without the need to use measurement of the current drawn, establishing the torque level based on measurement of the brushless motor rotation speed. The rotation speed corresponding to the nominal torque has therefore been previously established so that when there is over-torque, the rotation speed is decreased. This makes it possible to infer that there is over-torque, thus achieving torque protection for brushless motors which is effective, simple and highly economical.
The mechanism is comprised of the following: A power supply (1), a rotation direction setter (2), a control unit (3) which is connected to the rotation direction setter (2); a brushless motor (5) which has a connection for sending a BREAK instruction from the control unit (3) to the motor (5), a signal which is sent when a shutdown occurs due to over-torque.-

摘要： Opening and closing mechanism which is comprised of the following:
- A power supply (1)
- A rotation direction setter (2)
- A control unit (3) which is connected to the rotation direction setter (2)
- A valve actuator motor (5) which is connected to the control unit in which one of the connections is for sending a BREAK instruction from the control unit (3) to the motor (5), a signal which is sent when a shutdown occurs due to over-torque inferred from the motor rotation speed.
This opening and closing mechanism is not limited by any wear of the plug, has no need to use measurement of the current drawn and establishes the torque level based on measurement of the motor rotation speed, the rotation speed corresponding to the nominal torque having been previously established.-

摘要： Self-recalibrated valve comprising a stem (1) longitudinally movable by the action of an actuator (4), and which has associated at its free end a shut-off valve member, which includes an absolute positioning encoder (2) that transmits at all times the stem position as well as the valve opening and closing points, determining the total run, wherein the opening point corresponds with the open valve position and the closing point is established from the point at which the actuator performs the maximum controlled torque based on the rotational speed of the motor and electronic means (5), which in turn comprise a first microprocessor (6), in charge of receiving the signals from the absolute encoder (2), and a second microprocessor (7) in charge of controlling and monitoring the motor, as well as means of connection with the outside.

摘要： The invention relates to a voltage discriminator comprising three inputs, wherein one of them is for a common signal and the other two are the signals to be discriminated, with each of the three signals being input to a three-phase rectifier bridge, wherein a measurement signal is taken from the signals to be discriminated by means of a high impedance measurement resistor, allowing a very low current to pass, with each high impedance resistor being connected in series with an offset signal generator and the output of which is compared with the other signal without any reduction in value in a comparator, wherein the output of each comparator is a logic value "1" or "0" if the value is greater than a threshold value or not, respectively. The discriminator is suitable for multi-voltage sources, wherein the discriminator itself adapts automatically to the input voltage, wherein the discriminator furthermore has a lower energy consumption, is of great simplicity and high functionality.
