Y2 series of enclosed-totally self-cooling squirrel 3-phase
asynchronous motors is designed on the basis of Y series of motors.
Generally it is used for basic series of motors. its property
indexes are up to the foreign 1990s level. Its seat number is
extended upward(355) and downward (63 and 71) so that China has a
complete low-voltage 3-phase asynchronous motor series. The power
classes and installation size conform to IEC60034 standards, and
consistent with Y series (80—35 seats).
