l¡¢YZR.YZ. series motors for crane and metal-lurgical uses ,featured with large overload capacity and adequate mechanical strength ,are specially suitable for driving various types of crane and metallurgical mechineries or other similar equipment.
YZR series motors are of wound rotors type,while YZseries motors are of squirrelcage type.
2¡¢ The moor will operate satisfactorily under following conditions:
(1) temperature of coolant not exceeding 40¡æ(for crane uses) of 60¡æ(for metallurgical uses).
(2) Altitude form sea-level not exceeding 1000m.
(3) Frequent and significant mechanical vibration and shocks.
(4) Frequent starting ,braking(electrical or mechanical) or reversing.
3. The rated frequency of the motor is 50Hz and rated voltage is 380V.
4. Connection : The stator winding is connected in Y for 132KW and delow and in ¡÷ for the rest. In Y with zero leader is also supplied.
5. Type condification. |
