Abstract

A production method for a modularized arc motor belongs to the technical field of motors. The production method for the modularized arc motor comprises the steps of assembling an intermediate assembly, arranging a rotating shaft of the intermediate assembly on a supporting part to enable a module installation part to be at a preset position, fixing an arc motor module to be installed on the module installation part at the preset position, connecting windings of the arc motor module with a motor drive controller, introducing set current to the motor drive controller, detecting whether the module installation part adjacent to the next position can rotate to the preset position, executing step S5 if the module installation part adjacent to the next position can rotate to the preset position, executing step S3 if the module installation part adjacent to the next position can not rotate to the preset position, disconnecting the windings from the motor drive controller, re-executing step S3, and circulating until installation of all the arc motor modules is completed. The production method for the modularized arc motor achieves the purpose of detecting the qualification rate of the stator module unit in the motor assembly process, and greatly shortens the whole production period of the arc motor.
