Description

Technical Field

[0001] The utility model relates to the field of jacquard equipment, in particular to a device for reducing the fluctuation of an electronic jacquard machine following the movement of a loom. Background Art

[0002] During the operation of the loom and jacquard machine, the loom main shaft drive motor is usually controlled by the loom electronic control system. An encoder can be fixed on the loom drive shaft. The encoder receives the operating condition of the loom drive shaft motor and provides the position information to the jacquard main shaft motor control system to control the jacquard main shaft drive motor, allowing the jacquard to follow the position, reduce fluctuations, and achieve synchronization.

[0003] Due to the problem of excessive fluctuations in working conditions during the operation of the loom, the servo motor of the jacquard machine will frequently accelerate and decelerate to keep following the loom. On the one hand, it will cause the servo motor to generate heat sharply and reduce the life of the servo motor. On the other hand, the frequent acceleration and deceleration of the servo motor will increase the bus voltage of the servo drive. Since the servo drive bus voltage is too high, it will damage the internal components of the servo drive, so it is necessary to add a brake resistor to the bus voltage to consume the braking energy. Therefore, the frequent acceleration and deceleration of the servo motor to increase the bus voltage will cause the brake resistor to work frequently, which not only increases energy consumption, but also increases the temperature of the brake resistor and increases the failure rate, which needs to be improved.
