    摘要: The invention concerns a method for controlling an electric motor driving a body in translation between an initial position and a final position determined by a stop, by powering the motor with reduced voltage in the final position approach phase. The motor has a torque/speed characteristic such that the torque at null speed decreases with the supply voltage. As the approach phase starts, the method consists in determining a reduced voltage by decreasing the rotational speed of the motor from a nominal value to a predetermined reduced value and in cutting the motor power supply if the motor rotational speed drops below a predetermined threshold value.

    摘要: A barrier operator moves a movable barrier using a motive source having a movable member, a station, and first and second flexible members. The station includes a drive system operatively coupled to the movable member of the motive source. The drive system includes input and output members. The first and second flexible members each have first and second ends and a portion extending from the station. The first ends of each flexible members are operatively coupled to the movable barrier and the second ends of each of the flexible members are operatively coupled to the output drive system member of the station. Aspects include the first and second flexible members being cable or wire. Other aspects include the output drive system member of the station being a spool. The drive system further includes a gear box operatively coupled to the spool. Other aspects include the movable barrier being a gate or door. Further aspects include the motive member being a 3-phase alternate current electric motor having a motor shaft as the movable member. The electric motor is supplied with 3-phase electrical power having voltage levels less than 65 volts root mean square. Additional aspects include calibration of fully opened and closed positions of the movable barrier, automatically positioning of the movable barrier by the barrier operator, supplying 0 hertz electrical power to the electric motor for heating based upon a temperature threshold, and control of frequency of the electrical power supplied to the motor based according to a continuous function of barrier position.

    摘要: A process and apparatus for positioning an object being moved along a path to a destination using a pole changing three-phase induction motor having at least two fixed driving speeds. The object is initially accelerated along the path of movement to the highest driving speed of the motor, during which the acceleration curve is determined and stored. The acceleration data is then used to calculate the location along the path in advance of the destination at which the motor is switched off and braked until reaching the next lower driving speed, whereupon the motor is operated at the next lower driving speed for a predetermined path length. The motor is then again switched off and braked until its driving speed reaches zero closely proximate the destination, at which point a motor in a gear assembly attached to the motor is operated for final low speed positioning of the object at the destination with a high degree of accuracy. The calculation of the initial switch-off location using, in the preferred embodiment, the dynamically-determined acceleration curve results in rapid and highly accurate object positioning without the need for undesirable buffer paths.
