Three-axis integrated frequency converter

Abstract

The embodiment of the invention provides a three-axis integrated frequency converter which comprises a first surface of a bottom shell and a cover shell which form a closed accommodating space, and a circuit board used for bearing a frequency converter circuit is arranged in the closed accommodating space; the circuit board is provided with a frequency conversion interface and an RJ45 communication interface which are sealed and extend to the outside of the frequency converter. The frequency conversion interface comprises a frequency conversion input interface and three frequency conversion output interfaces; a groove is formed in the second surface of the bottom shell, and a cooling fin is arranged in the groove; the radiating fin, the bottom shell and the circuit board are in sealed connection; a heat dissipation window is arranged on the side face of the bottom shell. According to the frequency converter, in an application scene where a plurality of devices need to be controlled synchronously or separately, the use number of the frequency converters can be reduced, the device purchase cost is reduced, the workload of device installation and maintenance is reduced, meanwhile, the waterproof performance is improved, the situation that the circuit board is corroded due to damp is effectively prevented, and the service life of the frequency converter is prolonged. The service life is prolonged, and the stability of the whole system is improved.
