Description
Affiliated technical field
The utility model relates to the application technology of a kind of brshless DC motor on weaving electrical equipment, and concrete is a kind of energy-saving electronic weft accumulator, affiliated electromechanical integration technology area.
Background technology
In loom running, to the requirement of weft accumulator, be: the yarn storing on storage cylinder surface should supplement the consumption of yarn in time according to loom, accomplish yarn storage amount substantially constant on storage cylinder, and should not occur that yarn is found time, excess is rushed yarn phenomenon.
In the prior art, while realizing storage latitude function, generally to adopt following parts: winding yarn also can be realized the transmission mechanism of speed governing, store and the yarn storage cylinder of drawn work, detecting element and detection signal is carried out to the controller etc. of fuzzy recognition spinning velocity.The transmission mechanism of existing weft accumulator, consists of threephase asynchronous machine and AC converter, and therefore the common feedback signal of received code device not of frequency converter can not carry out closed-loop control, easily causes excess to rush yarn and yarn finds time to cause broken yarn phenomenon.And detect with detecting element the way that the weft yarn coiling number of turns adjusts winding speed as feedback signal, not only increase manufacturing cost, but also increased trouble point.In a word, existing weft accumulator has following several large shortcoming: (1) owing to having adopted threephase asynchronous machine driving, causes that energy consumption is high, temperature rise; (2) in order to meet heat radiation requirement, increase area of dissipation, caused volume to increase, increased manufacturing cost; (3), owing to can not carrying out closed-loop control, excess rushes yarn and yarn finds time to cause broken yarn phenomenon serious, affects production efficiency and fabric quality.
Summary of the invention
In order to overcome, existing weft accumulator volume is large, power consumption large, weft tension is controlled deficiency inhomogeneous and that fault rate is high, the utility model provides a kind of brshless DC motor and control technology to be applied in weft accumulator, this utility model can not only make electric part and mechanical driving part combine together, realize truly integrated, make volume, material reduce 1/3rd, motor temperature reduces half, and can using electricity wisely more than 40%, and power test contrast is as following table:
The utility model solves the technical scheme that its technical problem adopts: microcontroller is connected with power supply, and inverter circuit is connected with power supply, and encoder is connected with power supply, is provided after power supply in preparation state respectively by power supply.It is characterized in that receiving after the working signal of action button and weaving loom when microcontroller; output pulse drives brshless DC motor to enter duty to inverter circuit; the microcontroller analog signal that also received code device and weft sensor and rotor-position sensor are exported in real time; three groups of data compare after calculating, and output pulse is carried out corresponding speed to inverter circuit to brshless DC motor and controlled or brshless DC motor, weaving loom are shut down to control.This control method can obtain wider speed adjustable range, less percentage speed variation and level and smooth speed adjusting performance, and reliability has had larger raising.
The beneficial effects of the utility model are: external form is compact, simple in structure, high efficiency, low noise, energy consumption are low, compared with long life etc., and main is production efficiency and the fabric quality that has improved supporting loom.
