TQFR-3000 synchronous traction generatorDetailed product description：

The TQFR-3000 synchronous traction generator is a new product that combines China's traditional synchronous main generator structure with advanced motor manufacturing technology from abroad. This type of motor has a large constant power voltage regulation, which can effectively reduce the depth of magnetic field weakening of the traction motor, improve the reliability of locomotive operation, and is equipped with E32626QTY improved bearings, which further increases reliability. It is the prototype of TQFR-3000 series. Main locomotive models: Dongfeng 4, Dongfeng 4B, Dongfeng 5, Dongfeng 7.
