Embodiment Construction

[0072] Hereinafter, the present invention will be further described in detail with reference to the accompanying drawings and embodiments, but the embodiments of the present invention are not limited thereto.

[0073] The system structure block diagram of the method and device of the present invention is as follows figure 1 As shown, it consists of a rectification control unit and a speed adjustment unit. The rectification control unit inputs a single-phase 220V AC power supply from the phase line input terminal L and the neutral line input terminal N, and outputs a controllable rectification voltage from the first controllable rectification output terminal AC1 and the second controllable rectification output terminal AC2. The speed adjustment unit inputs a controllable rectification voltage from the first controllable rectification input terminal AC1 and the second controllable rectification input terminal AC2 and controls the speed of the stepping motor.

Abstract

A method for remote speed regulation of a stepping motor is achieved by a device composed of a rectification control unit and a speed regulation unit. The rectification control unit is used for inputting a single-phase 220V alternating current power supply, outputting a controlled rectification voltage subjected to voltage drop by a transformer and sending a speed control signal comprising a motor running direction and a running speed level in the controlled rectification voltage; the speed control signal comprises a speed data wave composed of direction guide waves of three power frequency periods and a plurality of power frequency periods; and the speed regulation unit is used for inputting the controlled rectification voltage containing the speed control signal and controlling the speed of the stepping motor. In the method, a remote controller is not needed, a control line is unnecessarily and independently laid, a single-phase power line is directly used for transmitting the speed control signal, and remote control and regulation on the speed of the stepping motor can be achieved.

Description

Technical field [0001] The invention relates to a motor speed regulation technology, in particular to a method for remote speed regulation of a stepping motor. Background technique [0002] When you need to remotely control and adjust the speed of a stepper motor, the usual methods are: [0003] One is to use remote control. The drive control circuit of the stepping motor is equipped with a remote control receiving device, and the stepping motor can be adjusted stepwise or steplessly through the remote control. The disadvantage is that it needs to be equipped with a remote control, management is troublesome, and the remote control is easy to lose . [0004] The second is to adopt digital control technology. For example, the RS-485 bus is used to control the speed of a stepper motor. This solution has advanced technology but high cost. In addition to laying power lines, the system also needs a digital control bus. [0005] The third is to use analog signal control technology. For ...
