Brief Introduction

For ZTP series electric railway motors, its structure type according to the different requirements of users, the motor can be made into a steel plate welded round frame ZTP-1~8 frame; And octagonal full laminated ZTP-100~200 stand DC motor. ZTP-1~8 ZBT fully enclosed motors can be produced according to different places of use.

The cooling mode of the train DC motors is IC01, and other cooling modes of the motor can also be produced according to the requirements of use. The protection grade of the motor shell is IP22, IP23(ZTP series); IP44(ZBT series). The basic installation form of the motor is IMB3, IMB5, IMB10, IMB30, IMV10, etc. According to the needs of users can also be made into other installation forms, single shaft extension or double shaft extension motor. The power supply of the motor supplies power to the unit, such as static rectifier power supply, must control the rectifier pulse number should not be small 6, the peak ripple factor of the power supply does not exceed 6%6, the working system of the electric railway motors for sale is S1 or S4.
