T series industrial air compressor motor

PUTAI T Series Industrial Synchronous Motors are three-phase motors rated 400–10,000 kW, with voltage options from 6 kV to 11 kV. Designed for large compressors, fans, blowers and pumps, they serve OEMs, industrial distributors, system integrators and buyers seeking replacement motors.

Welded Steel Frame
The welded steel frame provides the motor's main structural support. The frame, shaft and bearings must match the driven equipment and installation layout.

Stator Core and Winding Insulation
The stator combines a laminated core with insulated copper windings. The manufacturing process includes winding insulation, vacuum pressure impregnation (VPI) and drying.

Rotor and Excitation System
The rotor uses field windings with thyristor-controlled excitation. The excitation system must match the motor ratings and operating requirements.

Cooling Configurations
IC01 and IC37 cooling options are listed. The appropriate configuration depends on the motor design, heat dissipation requirements and installation conditions.

Industrial Air Compressors: Main drives for large process-air, refrigeration and industrial gas compressor systems.

Fans and Blowers: High-power ventilation fans, process-gas circulation fans and industrial blower systems.

Pumping Systems: Large pumps serving industrial processes and utility systems.

Chemical and Fertilizer Plants: Compressor and other heavy-duty rotating-equipment drives in continuous production processes.

Steel and Heavy Industry: High-power process and auxiliary drives requiring compatible motor ratings and speeds.

Replacement and Retrofit Projects: Replacement motors for existing synchronous drives where electrical, mechanical, cooling and excitation interfaces must match.

OEM Integration
For new equipment projects, motor selection and integration require matching the electrical ratings, shaft and mounting interfaces, cooling arrangement, excitation equipment and driven-machine requirements. Technical drawings and interface specifications help coordinate the motor with the equipment layout and drive system.
For repeat orders, approved drawings and specifications can serve as references, with changes reviewed before reuse.

Replacement Motors
For replacement enquiries, provide the existing motor nameplate and outline drawing where available. Shaft dimensions, mounting, electrical ratings, cooling configuration and excitation interfaces must also be checked; matching power alone does not establish interchangeability.
Product specifications, drawings and available inspection or test records can support engineering review, installation planning and maintenance.

PUTAI's motor manufacturing operations cover silicon-steel preparation, copper winding, insulation processing, VPI, drying, assembly and testing before dispatch.
Company-level resources include a reported plant area of 200,000 m², RMB 80 million in fixed assets and more than 120 employees, including 18 technical engineers. PUTAI reports over 25 years of motor industry experience. Product-specific manufacturing photos and records can help buyers assess the T Series production process.

Quality checks should correspond to the motor specification and project requirements. Relevant areas include winding and insulation inspection, mechanical assembly, cooling and auxiliary interfaces, and finished-motor testing.
Available documentation may include technical specifications, drawings and inspection or test records for equipment integration, installation and maintenance.
