Abstract

The invention discloses a variable frequency magnetic variation speed device with a three-phase motor. The variable frequency magnetic variation speed 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 magnetic variation speed device also comprises a frequency converter which is connected with the power input end of the three-phase motor. 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 magnetic variation speed device can be applicable to various working places.

Description

technical field [0001] The invention is a device for controlling a steering pump by driving a magnetic transmission with a three-phase motor, which is suitable for the steering pump with adjustable head. Background technique [0002] The current motor and steering pump are all split designs. Due to the needs of use, a magnetic transmission is often added between the motor and the steering pump, and the rotation speed is adjusted through the magnetic transmission. However, the overall structure is relatively complicated, and the installation and use of the three devices are relatively cumbersome. In the process of fixing, if the concentricity of the three devices is not good, it is easy to cause damage to the magnetic transmission. Contents of the invention [0003] The purpose of the present invention is to provide a three-phase motor frequency conversion magnetic transmission device with good sealing performance, stable equipment and integrated design. [0004] The purpo...
