Embodiment 1

[0027] Such as figure 1 , figure 2 As shown, before the DC motor control system works, two inputs should be connected, namely AC 220V and AC 380V, among which the AC 220V is converted to DC 24V by the 24V conversion power module power module M5, and converted to DC by the 36V conversion power module M4 36V; AC 380V provides working voltage for the amplifier through the AC motor control circuit. The output end of the external control box is connected with the input port of the amplifier, and finally the first travel switch 1 and the second travel switch 2 are connected to the system through a cable and installed on the limit position of the turntable.

[0028] Press the first button switch K1, the wire pack of the first relay M1 is powered on, and the normally open contacts M11, M12, M13 provided by the first relay M1 are closed accordingly. In the main circuit unit, the contact M11 and its wire package form a power-on self-locking, release the start button, M11 is still clo...

Abstract

The invention relates to a direct-current motor forward and reverse rotation control system, and belongs to the field of direct-current motor control. The direct-current motor forward and reverse rotation control system comprises a main circuit unit, an expander control circuit and an alternating-current motor control circuit unit. The main circuit unit comprises a 24V conversion power supply module and a commutation circuit module; the expander control circuit unit comprises a 36V conversion power supply module and an expander; and the alternating current motor control circuit unit comprisesan alternating current module. Control current direction conversion is completed through the commutation circuit module so as to drive the direct current motor to rotate forwardly and reversely. Debugging personnel do not need to manually control the direct current motor to steer according to actual operation conditions to complete running-in operation of the rotary table, and the working efficiency is improved.

Description

technical field [0001] The invention belongs to the field of DC motor control, and in particular relates to a DC motor forward and reverse control system. Background technique [0002] A laser digital collimator is a semi-automatic photoelectric aiming solution system composed of a tracking turntable part, a control cabinet under the cabin and a heading gyro box. All parts of the system are connected together through the tracking turntable. The running status of the tracking turntable directly affects the stability of the entire system. In order to remove high points and burrs on the tooth surface and improve the stability and transmission accuracy of the turntable, it is necessary to Then run the turntable for a certain period of time. However, in the current working mode, the commissioning personnel manually control the steering of the DC motor according to the actual operating conditions to complete the running-in operation of the turntable. The long running-in process l...
