Production Process
PUTAI's industrial motor manufacturing process covers material preparation, core manufacturing, winding, insulation treatment, rotor manufacturing, motor assembly, and inspection and testing.
Production operations follow the motor design and applicable technical specifications. Checks at relevant stages cover component dimensions, winding work, assembly accuracy, and finished-motor performance.
Silicon Steel Preparation & Core Manufacturing
Silicon steel sheets are prepared and processed for motor stator and rotor cores. Core manufacturing involves material preparation, lamination processing, and dimensional checks.
Core dimensions and lamination quality are controlled to meet the motor's design and assembly requirements.
Copper Winding
Copper conductors are processed into stator windings and, where applicable, wound rotor windings. The work includes conductor preparation, winding, and the arrangement of winding components.
Winding dimensions and arrangement follow the applicable motor design and electrical specifications. Relevant checks are carried out during the winding process.
Insulation Treatment
Insulation materials are applied to winding components to provide electrical insulation between conductors and other motor components.
The insulation system is selected according to the motor design and voltage rating. Insulation work is coordinated with winding operations and subsequent treatment processes.
Rotor Manufacturing
Rotor components are processed and assembled according to the motor structure. Manufacturing checks cover relevant component dimensions, mechanical fit, and assembly requirements.
Vacuum Pressure Impregnation (VPI) & Drying
For motor windings designed for VPI treatment, vacuum pressure impregnation is used as part of the insulation process, followed by drying.
The treatment helps insulating materials penetrate and consolidate the winding insulation system. The applicable process follows the winding design and insulation requirements.
Motor Assembly
Stators, rotors, bearings, housings, and other components are assembled according to the motor design and technical specifications.
Assembly checks focus on component fit, installation dimensions, and mechanical accuracy to meet the motor's specified configuration.
Inspection & Testing
Inspections are carried out at relevant manufacturing stages and before dispatch. Checks cover applicable components, winding work, assembly, and finished-motor requirements.
Electrical and mechanical tests are performed according to the applicable product specifications and order requirements. The inspection scope depends on the motor type and agreed technical requirements.
Finished Motor Preparation & Dispatch
After final inspection and testing, finished motors are identified and prepared for packing and delivery. Product identification, packing arrangements, and dispatch preparation follow the confirmed order requirements.
