2. Construction
This series motors, used with self - fan cooling, fit with outer fan and end shield
at the non-shaft extension end, which are constituted external cooling system with
the cooling tube around the frame.
The insulation class is F. The stator coil is made of flat copper strips covered
with double glass fiber mica tape .So the stator windings are in the nature of higher
electric strength, mechanical strength, insulating property, water resistance and heat
stability.
The rotor has adopted the squirrel-cage construction. In the results of precision
dynamic balancing, the motors are able to run smoothly with little noise and vibration.
High-voltage terminal boxes are half-inclined plane with a large terminal
compartment within which positions of cable head are left.
The construction of shaft via hole is adopted with the axial labyrinth which are ingeneral use around in the most advanced countries. So, the motors can
manufactured for ExdI ExdIIA, ExdIIB, ExdIIC, ExeIIT1, ExeIIT2 or ExeIIT3.
The bearing structure is adopted with three bearing structure used in ones of
Siemens AG. the shaft extension end is fitted with double bearings, one of the two is
a ball bearing , to prevent the bearing moves to the shaft extension end. In this way,
the motor runs safely and reliably.
The motor is equipped with lubricating device at the two ends without stop
running, thus the grease will be filled regularly. the bearing thermometer can be fitted
in order to monitor bearing temperature, as the customer required. In addition, the
