Abstract

The invention discloses a three-phase motor integrated controller and aims to provide a three-phase alternating current asynchronous motor control device to replace a traditional control method. The three-phase motor integrated controller comprises a housing. The three-phase motor integrated controller is characterized in that the housing is provided with a power output board and a mainboard, wherein the mainboard is installed on the power output board. The mainboard is provided with a master controller chip automatic voltage regulation (AVR) chip, a power light, a running light, an alarm light, a current regulating switch and an alarm reset button. The power output board is provided with a power supply input terminal, a supply output terminal, a direct current 24V input terminal and a motor positive and negative inversion control terminal. A silicon controlled module is used for connecting and disconnecting a power circuit. A current transformer module is used for detecting an output current of the three-phase motor integrated controller and transmits detected data to the master controller chip AVR chip.

Description

technical field [0001] The invention relates to a control device for a three-phase AC asynchronous motor, in particular to an integrated controller for a three-phase motor. Background technique [0002] Such as Figure 7 As shown, it is a traditional three-phase AC asynchronous motor control circuit; the left figure is a three-phase AC asynchronous motor forward and reverse control circuit, using two master switches SA1, SA2 (or two intermediate relays KA1, KA2), 1 1 air switch QF1, 2 AC contactors KM1, KM2, 1 thermal protection relay FR1, 1 resistance-capacitance interrupter RC1, and connected through complicated wires and terminals; the right picture shows a three-phase AC asynchronous motor in one direction Rotation control circuit uses 1 master switch SA3 (or 1 intermediate relay KA3), 1 air switch QF2, 1 AC contactor KM3, 1 thermal protection relay FR2, 1 resistance-capacitance interrupter RC2, It is also connected through complicated wires and terminals; the above-men...
