ZZJ-818 186kW DC rolling-mill auxiliary motor

CATALOGUE OVERVIEW

About this motor series

Wangpai’s ZZJ-818 is a rolling-mill auxiliary DC motor. The table’s 186 kW entry lists 410 rpm for series excitation and 435 rpm for compound or shunt excitation under the stated duty column. Other intermittent-duty columns give different outputs, so 186 kW is not a universal rating for every duty. The 818 frame is listed with 0.75 m³/s external ventilation and a 1500 rpm maximum safe operating speed.

The table distinguishes S1, S2 and S3 duties and excitation types. Select the complete duty and excitation column before using a rating.
