Triple-Phase Asynchronous Motor

l,YZ series is the newly designed electric motor with the characteristic of large overload capacity and high mechanical strength, enough for driving all sorts of metallurgical machinery and hoisting machine or the other similar equipments.YZR series motors are wound rotors type,while YZseries motors are squirrelcage type.

380V, 50Hz, AC, 3-phase

Basic Duty: S3-40%

Insulation Class: F, H

frame size: 112mm-280mm
2,The motors will operate normally under the following conditions:
(1) temperature of coolant not exceeding 40(for crane uses) or 60(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 : for motors with power of 132KW or below, Y type connection;T others: tye connection. Motors using Y connection can also add zero wire.
5. Type codification.

6,Output and speed
The range of rated output and ,asynchrouons speed for the basic duty type (S3-40) are shown in table 1.
