Standard WY motors are three phase totally
enclosed fan cooled(TEFC) cast-iron induction motor with
IEC frame size from 63 to 450. WY motors are suitable for
continous S1 duty, which means that it can operate under
constant load and lasting long enough to allow the machine
to reach thermal equilibrium. The efficency of WY motors reach the IE1 standard.
The WY series is used for general purpose
applications in machines such as fans, pumps, electric power
packs and etc.
