Features and application
ZSN4 Series Cement Rotary Kiln DC Motor is a kind of special motor which is developed based on the characteristics of cement rotary kiln main drive.
ZSN4 Series Cement Rotary Kiln DC Motor adopt octagon structure and the availability of stator space is high, stator magnetism yoke is terrace, which can suffer from the pulsating current and rapid upheaval in current, and is applicable to triphase all control bridge commutate's power. And the motor can work for a long time without calm wave reactor. Novel class F insulating structure makes insulating function stable and easy to dissipate heat.
Designing on the basis of the characteristics of cement rotary kiln makes start moment 2.5 times as rated moment. The cooling method of using pipe-ventilating makes the motor operate safely and dependably in the bad environment with dust.
The size of motor comply with ICE72 international standard, except for the axial distance between the mounting holes (dimension B).
