TK series Motor Introduction

Overview
The TK series 6kv synchronous motor three-phase synchronous motors are specially engineered for air compressor applications, serving as the core drive solution for equipment in the refrigeration and fertilizer industries. Designed for reliable industrial operation, the standard starting method is full-voltage direct starting; for installations with limited grid capacity, reduced-voltage starting is available as an optional configuration.
Fully compliant with national standards, the motors meet GB 755 Rotating Electrical Machines – Rating and Performance and JB/T 8667.1-2011 Technical Specifications for Large Three-Phase Synchronous Motors Part 1: TK Series, ensuring consistent performance and quality for industrial applications.

Construction & Design
The series 6kv synchronous motor offers two structural and mounting configurations to match compressor designs:
IM7311
Equipped with a drive shaft and pedestal bearing
IM5710
Without a drive shaft and pedestal bearing
The standard cooling method is open self-ventilation (IC01), with custom solutions such as ducted ventilation available upon request. The excitation system of high voltage synchronous motor adopts a thyristor-controlled excitation device, delivering stable magnetic field control and reliable operation across load conditions.
.
Application Industries
While primarily designed for driving air compressors, the TK series 6kv synchronous motors are also suitable for powering other industrial machinery, including water pumps, blowers, and other high-power transmission equipment, making them a versatile solution for various industrial drive systems




Ordering Information
