Problems solved by technology

[0002] The traditional hoisting system for cranes adopts the structural form of drive motor, reducer, brake and coupling. The system has long transmission chain, large mechanical loss, high failure rate, and takes up a lot of space. The drive motor adopts a three-phase motor, and the three-phase When the motor has a phase failure, it will cause downtime and production stoppage, which will affect the normal operation of the system; if it is serious, it will cause serious accidents, resulting in huge losses to personnel and property

Abstract

The invention relates to a permanent magnet direct drive lifting system with the fault tolerance function for an integrated crane. The permanent magnet direct drive lifting system with the fault tolerance function for the integrated crane comprises a crane trolley frame, a permanent magnet direct driver motor built-in lifting mechanism, an electric energy recovery unit and a frequency conversion controller. The permanent magnet direct driver motor built-in lifting mechanism comprises a brake, a winding drum and a multiphase permanent magnet synchronous direct driver motor. Both ends of the winding drum are installed on a bearing seat through bearings. The multiphase permanent magnet synchronous direct driver motor is built in the winding drum and is fixedly connected with the crane trolleyframe through a bracket. The multiphase permanent magnet synchronous direct driver motor comprises two output shafts, one of the two output shafts is connected with the brake and the other is fixedlyconnected with the winding drum. The frequency conversion controller is used for controlling the multiphase permanent magnet synchronous direct driver motor. The electric energy recovery unit is usedfor recovering electric energy generated by the operation of the multiphase permanent magnet synchronous direct driver motor. The permanent magnet synchronous motor is built into the winding drum, and the permanent magnet direct drive lifting system with the fault tolerance function for the integrated crane has the advantages of small volume, light weight and short transmission chain.

Description

technical field [0001] The invention relates to a permanent magnet direct drive lifting system for an integrated crane, in particular to a permanent magnet direct drive lifting system for an integrated crane with a fault-tolerant function. Background technique [0002] The traditional hoisting system for cranes adopts the structural form of drive motor, reducer, brake and coupling. The system has long transmission chain, large mechanical loss, high failure rate, and takes up a lot of space. The drive motor adopts a three-phase motor, and the three-phase When the motor has a phase loss fault, it will cause downtime and production stoppage, which will affect the normal operation of the system; if it is serious, it will cause serious accidents, resulting in huge losses of personnel and property. Contents of the invention [0003] In order to solve the problems existing in the above-mentioned background technology, the present invention proposes an integrated permanent-magnet ...
