    Tips: Application of stepper motor into mine hoisting

    Stepper motor features simple structure, large power, convenience in maintenance, high positioning accuracy, good reliability, small volume and as many as 32 choices for the drive system, low price, no accumulated location error, self-locking and low cost, so it is widely applied. Additionally, along with the application control of SCM using mature microcomputer technique, automatic control can be easily realized. Above characteristics completely meet the requirements of micro drive. Besides, automatic control of mine hoisting system and unattended duty hoisting system can be realized.
    As for the control process of the stepper motor during mine hoisting, firstly, mine hoist reducer approaches the crawling stage and the velocity is reduced to about 3m/s, the electromagnetic valve is powered on with automatic control system. The electromagnetic valve rod overcomes the elastic force shift down of spring under the role of electromagnetic force so that the compressed air enters the cavity B from A and enters the gasbag clutch through hollow shaft of reducer, so that micro drive device can be connected with the host.
    When the velocity is continuously reduced the crawling speed, the dynamic brake power of the main motor is cut off by controlling the circuit. The hoister crawls at stable low velocity from stepper motor drive. By hoisting the vessel to the end point to unload, control circuit to cut off the electromagnetic valve, so that the stepper motor is separated from main engine to complete the crawling process for once. Then, follow the next cycle, by improving and reducing the occurrence rate of accidents when unloading, the safety of coalmine production can be enhanced and foundation for automation production of the coalmine can be laid.

    Great value
    Received all three nema 23 stepper motors last week. Hooked them up and tested them. No issues found, very happy! Highly recommend! I will order more.
