摘要： Pairs of phases of an AC power source are connected to pairs of phases of a motor in a first sequence that repeats at a first frequency. The motor is braked by connecting pairs of phases of the AC power source to pairs of phases of the motor in a second sequence that is reversed with respect to the first sequence and that repeats at a second frequency less than the first frequency. In further aspects, pairs of phases of an AC power source are connected to pairs of phases of a motor in a first sequence. The motor is subsequently disconnected from the AC power source for a predetermined dwell interval having a duration greater than a time constant of the motor. The motor is braked using a second sequence that is reversed with respect to the first sequence.

摘要： The present disclosure discloses a brushless DC motor braking system and method. during the braking process of the brushless DC motor, the busbar voltage value is controlled to always be between the high threshold of the busbar voltage and low threshold of the busbar voltage through the brake control module; and different PWM modulation signals are used to control the brushless DC motor 4 to perform slow braking until stopping based on different busbar voltage states. Thus, in the present disclosure, the method not only ensures that the busbar voltage value continues to be maintained between the high threshold of the busbar voltage and low threshold of the busbar voltage, thereby protecting electronic components and circuits and extending their service life; but also avoids the hard braking method of direct conduction of the three lower transistors of the three-phase inverter in related arts.

摘要： A brake control system of a motor is provided. When a control circuit intends to brake the motor, the control circuit controls a driver circuit to turn off a first high-side switch and a second high-side switch, and to fully turn on the first low-side switch and the second low-side switch, for a period of time. Then, the control circuit controls the driver circuit to turn off one of the first low-side switch and the second low-side switch, and to continually turn on the other one of the first low-side switch and the second low-side switch, for a period of time. Then, the control circuit controls the driver circuit to turn off the other one of the first low-side switch and the second low-side switch, and to turn on the one of the first low-side switch and the second low-side switch, for a period of time.

摘要： A deceleration apparatus of an AC servo motor for use in an industrial sewing machine performs a regenerating braking operation during a motor deceleration period. At an early time in the regenerating braking operation of the motor, an intermittent regenerating braking operation is carried out by supplying a current in a control circuit of a motor drive circuit. Subsequently, a continuous regenerating braking operation in the motor is carried out. A drive element comprising a switching element or a transistor in the control circuit is protected in accordance with an intermittent regenerating braking operation or a small regenerating braking current.

摘要： An automatic reverse system for a shredder machine automatically causes reversal of the shredder motor when the system becomes jammed. A centrifugal switch connected with a starter winding of the drive motor disconnects power feed thereto when the motor is rotating above a predetermined speed. A manually actuated switching circuit in combination with the centrifugal switch initially energizes the system for forward operation. When a jam occurs, the centrifugal switch together with the switching circuit automatically causes a reversal in the direction of rotation of the motor, the reverse operation continuing until the operator manually actuates a switch to deenergize the system or when an automatic switch halts reverse rotation after a predetermined time period.
