T series is mainly used to drive fans, pumps, compressors; TK is mainly used in piston compressors. Through years of experience accumulation, finite element simulation optimization has improved the performance of this series of motors. The motor can meet the performance requirements of unit start-up and operation at the same time, the motor operation vibration, noise is less, and the operation is more reliable. Especially for high load large inertia fans and reciprocating compressors, our product performance is more superior.
