Variable frequency steering driving device of three-phase motor

Abstract

The invention discloses a variable frequency steering driving device with a three-phase motor. The variable frequency steering driving device comprises the three-phase motor, a steering pump and a magnetic variable speed device, wherein the three-phase motor is connected with the power input end of the magnetic variable speed device; the powder output end of the magnetic variable speed device is connected with the driving shaft of the steering pump; and the output shaft of the three-phase motor and the driving shaft of the steering pump are positioned on a same axis. Furthermore the variable frequency steering driving device also comprises a frequency converter which is connected with the power input end of the three-phase motor; and the magnetic variable speed device is provided with a shell in a sealed structure. The innovative design of the technical scheme is as follows: the three-phase motor, the magnetic variable speed device and the steering pump are integrally designed, and the variable frequency control over the motor is realized by virtue of the frequency converter, further the control over the steering pump lift is realized, and the variable frequency steering driving device can be applicable to various working places.

Description

technical field [0001] The invention is a steering pump device driven by a three-phase motor. Background technique [0002] Since the power output of the motor is fixed, the steering pump driven by the motor sometimes needs to be replaced with a steering pump with a different head according to the needs of use. Once the steering pump is replaced, the driving motor that drives the steering pump also needs to be replaced. Bring disassembly, replacement and other time and money costs to the user. If can design a kind of steering pump equipment that adopts a motor and just can adapt to multiple different models, sizes, just can well meet the needs of prior art. Contents of the invention [0003] The object of the present invention is to provide a steering pump device that can adapt to many different models and sizes. [0004] The purpose of the present invention is specifically achieved through the following technical solutions: [0005] A three-phase motor frequency conver...
