Z4 brush dc motor has advantage than Z2, It can not only be powered by DC unit power supply, but also suitable for static rectifier power supply. Moreover, the inertia is small, the dynamic performance is good, and the load change rate is high. The basic cooling method is IC06, It means it have a blower for ventilate, also it can be made for IC17, It means use pipe as the cold air inlet, the air outlet is shutter structure. Also it can be made for IC37, it means the cold air’s inlet and outlet both use pipe. And it has many deriving form, such as self-ventilation, axial flow fan type, enclosed type, air-air cooler type, etc. .
Z4 series large size dc motor 440v developed by our factory, which is a new product designed and manufactured with the latest technology. The base of this series of motors has 6 center heights, ranging from 315mm to 560mm.
The operating conditions of this series of motors:
It can be installed in a harsh environment, but the correct cooling method and protection class must be selected to keep the inside of the motor clean. The cooling air does not contain acids, alkalis and other gases that can damage the insulation and commutation of the motor, if it is used with dry ships or under wet tropical zone, and the working environment with salt, fog, humidity, etc., should be separately negotiated. The power supply adopts static rectified current or DC generator power.
