Background
In a circular knitting machine, power driving is one of indispensable key links, and the power consumption, the driving force and the stability of the driving force of a main motor directly influence the cost of a user and the quality of a product.
Traditional circular knitting machine generally adopts three-phase asynchronous machine as the power supply, cooperation mechanical reduction gears falls the rotational speed to the scope of regulation, the complete machine structure is complicated, the part is numerous, the installation and debugging are difficult, and because asynchronous machine is when the low speed, moment can't normally be full of the output, consequently the ubiquitous phenomenon that moment is not enough when leading to the circular knitting machine low-speed on the market, although later stage can be through variable frequency speed regulator increase starting torque, nevertheless lead to the motor overheated easily, cause motor insulation to descend, the life-span shortens. And, because three-phase asynchronous motor conversion efficiency is not high, in order to reach the required moment requirement of circular knitting machine, generally equipped with the motor that power is about 5.5KW, power consumption is big, unfavorable realization energy-conserving purpose.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome the shortcomings in the prior art and provide a power servo driving device of a circular knitting machine with simple structure, convenient operation and practicability.
The utility model discloses a realize through following mode:
a power servo driving device of a circular knitting machine comprises a servo motor stator connected to a large disc of the circular knitting machine and a magnetic yoke connected to a large disc gear; the big disc gear is connected to a big disc of the circular knitting machine and can rotate relative to the big disc of the circular knitting machine; the magnetic yoke is located on the inner side of the servo motor stator, a plurality of permanent magnets are arranged on the magnetic yoke at intervals, the permanent magnets are matched with the servo motor stator, the servo motor stator is connected with the servo motor driver, and the servo motor driver is connected with the circular knitting machine controller.
Furthermore, the servo motor stator is fixed at the bottom of the circular knitting machine large disc through a support.
The beneficial effects of the utility model reside in that: the servo motor stator and the circular knitting machine large disc are combined into a whole, the permanent magnet and the large disc gear are combined into a whole, a multi-stage speed reducing mechanism with a complex structure is removed, and the installation is simple; the permanent magnet brushless servo motor is adopted, so that the output torque is constant, and the operation is stable at low speed; the motor with the power of about two kilowatts can output power which meets the power requirement of the circular knitting machine, the power consumption is greatly reduced, the energy efficiency ratio of the power supply is improved, and the energy consumption is reduced; the rotating speed is greatly reduced, and the generation of resonance is avoided.
