Abstract

The invention discloses a high-voltage permanent magnet intelligent driving system for a water-conservancy vertical shaft. The high-voltage permanent magnet intelligent driving system comprises a shell, a stator assembly, a rotor assembly and a high-power permanent magnet motor driver, the length-diameter ratio of a rotor is larger than or equal to 11 and smaller than or equal to 20, the rotor assembly comprises two rotor units which are coaxial with each other and arranged on the same rotor rotating shaft in a sleeving mode, a magnetism isolating partition plate is arranged between the two rotor units, and the two rotor units and the magnetism isolating partition plate abut against each other. The high-voltage permanent magnet intelligent driving system has the beneficial effects that thelong and thin structure low-speed large-torque high-pressure permanent magnet intelligent driving system suitable for the water conservancy vertical shaft environment is provided, and the problems that energy consumption is large, a speed reducer is prone to damage, the maintenance period is short, maintenance cost is high, driving system noise is large, vibration is large and vertical shaft space is limited are solved.

Description

technical field [0001] The invention belongs to the technical category of a special motor for a water conservancy shaft in the technical field of permanent magnet motor manufacturing, and in particular relates to a high-voltage permanent magnet intelligent drive system applied to a water conservancy shaft. Background technique [0002] At present, the structure of the high-voltage and high-torque shaft pump drive system is a high-voltage asynchronous motor plus a coupling, an acceleration reducer, a coupling and an impeller. The asynchronous motor has the advantages of simple structure, high reliability, and a relatively simple control system. However, the asynchronous motor In terms of performance, the efficiency and power factor are low, which is not conducive to improving the working efficiency of the entire system and reducing costs; at the same time, the asynchronous motor has a slender structure, especially the concentricity level of the rotor must reach more than 3 lev...
