TK Series 6kv Synchronous Motor

PUTAI TK Series synchronous motors cover 250–4,000 kW and serve compressor OEMs, equipment integrators, distributors and industrial replacement projects. Their primary applications are large air compressors in industrial refrigeration and fertilizer plants.

Synchronous Drive for Large Compressors

Designed primarily for large air compressor drives, the motor's power, speed and starting characteristics must match the driven equipment and plant power supply.

Starting Arrangements

Full-voltage starting is listed as standard, with reduced-voltage starting also indicated as an option. The suitable method depends on the motor configuration, load inertia, starting torque and available supply capacity.

Thyristor-Controlled Excitation

The series uses thyristor-controlled excitation. Excitation equipment, control interfaces and protection requirements should be defined for the complete drive system.

Cooling and Mounting Options

The series lists IC01 and IC37 cooling methods and IM 7311 and IM 5710 mounting types. The chosen configuration must match site ventilation, installation layout and mechanical interfaces.

Air Compressors for Industrial Refrigeration
TK series motors are intended for large air compressor packages used in industrial refrigeration and cooling processes. Motor ratings, speed, starting arrangements and mounting interfaces should match the compressor specification.

Compressor Drives in Fertilizer Plants

The series is listed for compressor applications in fertilizer production facilities. Electrical ratings, operating duty, starting conditions and control-system interfaces are key project requirements.

Industrial Water Pumps
Water pumps are also identified as potential applications. Suitability depends on required shaft power, operating speed, load characteristics and installation conditions.

Industrial Fans and Blowers
The series may also be used for industrial fan and blower drives. The motor configuration must meet the equipment's power, speed, starting and mechanical interface requirements.

 

 

OEM Supply and Replacement Matching

 

OEM Supply for New Equipment
For new compressor packages, motor specifications should be coordinated with the driven equipment. Key information includes:

• Electrical ratings: Required power, voltage, supply frequency and operating speed.

• Load and starting: Load characteristics, starting torque, inertia, starting method and allowable starting current or voltage drop.

• Mechanical interfaces: Mounting dimensions, shaft and coupling details, bearing arrangements and foundation drawings.

• System integration: Cooling, excitation and protection interfaces, monitoring requirements and site conditions.

 

PUTAI can review the available specifications and drawings to identify configuration requirements and resolve technical discrepancies. Approved technical data and interface drawings should form the basis of manufacturing.

 

Replacement of Existing Motors

Replacement requires more than matching rated power and voltage. Shaft dimensions, mounting, bearings, cooling and excitation systems must also be checked.
For an initial review, buyers should provide the original nameplate and datasheet, general arrangement and foundation drawings, shaft and coupling details, electrical and excitation data, and installation photos where available. PUTAI can compare these details with the proposed configuration; final compatibility should be verified against approved drawings before manufacture.

 

Project Support

 

Project support may include technical data review, coordination of motor interfaces, and preparation of agreed datasheets, general arrangement drawings and connection diagrams. Inspection procedures, acceptance criteria and required documentation should be agreed before order confirmation, with any deviations recorded in the approved technical specification.

Frequently Asked Questions

 

Q: What are the main applications of TK Series motors?

A: The primary applications are large air compressors in industrial refrigeration and fertilizer plants. Water pumps, fans and blowers are also listed as potential applications, subject to operating requirements.

Q: What power and voltage options are listed?

A: The series covers 250–4,000 kW, with listed voltage options of 6000 V, 6600 V, 10000 V and 11000 V. The applicable combination depends on the specific model.

Q: Are all listed pole numbers and speeds interchangeable?

A: No. These options describe the broader series, not combinations available for every motor. Confirm the applicable pole number and speed against the technical data for the required configuration.

Q: Which starting methods are available?

A: Full-voltage starting is listed as standard, with reduced-voltage starting also indicated. The suitable method depends on the motor, driven load and plant power supply.

Q: Can PUTAI support motor replacement projects?

A: Yes. An initial review can use the existing motor's nameplate, drawings, electrical data and installation details. Compatibility must include mechanical interfaces, cooling and excitation, not just power and voltage.

Q: What technical and inspection documents can be provided?

A: Depending on the agreed scope, documents may include datasheets, drawings, inspection records and applicable test results. Requirements should be agreed before order confirmation.
