摘要： A sewing machine stopping control system brings a sewing machine from a high-speed operation to a stop without varying modes and with high stopping accuracy, for allowing the sewing machine to operate highly efficiently. According to the stopping control system, a motor is decelerated in response to a release of a foot pedal. At a time when a predetermined rotational speed or lower is detected, the deceleration operation is disabled regardless of a decelerating command BKON outputted from a speed command comparing circuit. Thereafter, when a predetermined needle position is detected, the deceleration operation is resumed. When a predetermined low speed is detected during the deceleration, the deceleration operation is again disabled. Thereafter, when a predetermined needle position is detected, the deceleration operation is again resumed so that the motor is completely stopped.

摘要： An improved speed controlling system for an electric motor, mainly used in a sewing machine includes a motor connected to a power supply, a speed controlling circuit or circuits for operating the motor at variably controlled speeds, and an electrical braking circuit or circuits for braking the motor upon receiving deceleration command from the speed controlling circuit(s) to transfer the motor from a high speed running state to a low speed running one. Electromechanical braking means are provided for acting on the motor, during at least a part of the braking period, the braking means being controlled by the electrical braking circuit(s). A low speed setting circuit is disposed in the speed controlling circuit(s) for maintaining the low speed running state caused by the electromechanical braking means and the electrical braking circuit(s). A stoppage commanding circuit is provided for stopping the motor operation, after the motor has been transferred to its low speed running state by a low speed setting circuit, by means of actuating again, owing to a stopping command, the electrical braking circuit(s) and/or the electromechanical braking means.

摘要： A method and apparatus through which a moving shaft is stopped in a predetermined angular position. The shaft is driven at a maximum speed through an electrically driven motor. When the shaft is to be stopped at the predetermined angular position, the shaft is decoupled from the motor and an electromagnetic brake is applied. A regulating circuit controls the braking action so that it is dependent on a comparison of the actual output speed of the shaft and a desired input speed, as well as the comparison of a computed braking angle and the predetermined angular position to which the shaft is to be rotated. Position and speed sensors connected to the shaft provide signals representing the instantaneous output position and speed of the shaft.

摘要： Apparatus for use with an A.C. induction motor drive for a sewing machine to supplant a clutch-brake mechanism by supplying an A.C. induction motor drive to supply power to the motor to control its operating speed and needle position. The control embodies a programmable controller responsive to information loaded into it to derive a profile of how the sewing machine is to operate to sew workpieces, and to generate a control signal which is supplied to the motor drive to operate the motor in accordance with the profile in association with a speed command encoder responsive to a manipulative operator control to produce speed signals to speed up or slow down. The encoder senses the position of the motor and provides a position signal representative of the needle and signals the controller in a closed-loop control system.

摘要： In a sewing machine, when the depressed condition of a foot pedal is changed from a forward depressed condition for high speed sewing to a reverse depressed condition for thread cutting, a braking circuit decreases the rotational speed of the machine motor from a high speed to a low speed. The rotational speed is detected by an encoder. When the rotational speed detected by the encoder becomes a threshold medium speed or less, and a needle-down signal is generated from a needle position detector, the CPU of the sewing machine outputs a work fabric feed pitch control start signal to a work fabric feed pitch selector. The work fabric feed pitch selector reduces or nullifies the feed pitch of the work fabric. Under this condition, in response to the next needle-down signal, the CPU operates a thread cutting mechanism to cut the needle and bobbin threads.

摘要： An electric motor of a sewing machine may be stopped naturally at an objective position by amending the amount of the motor's running errors as overrun or underrun with respect to the stop objective position without employing an especially forceful stopping circuit in spite of dispersions in a load inertia caused by mass-production of sewing machines or variances in loads during driving of the sewing machine.
