Crane Motor

These collection of metallurgical and crane 3-phase motor YZR, YZ with wound and squirrel cage rotor are specifically employed to generate metallurgical crane and other comparable equipment with greater overload ability and mechanical strength, consequently, it is suitable for quick time obligation or intermittent period responsibility and equipments with frequent beginning and braking or distinctive vitration and affect.
The regular selection of electrical power output and mounting dimensions are in comply with the reconmended regular of IEC 72, the relation in between assortment of power output and mounting dimensions are related to standard JEM1202 and West Germany standard DIN42681, so that most of them can be interchanged.
The motor can work nicely when the altitude does not exceed 1000m.
There are two lessons of F and H insulation, Course F is applicalbe to suit temperature which amazing air does not exceed 40 underneath regular problem, Course H is appropriate for metallurgical websites when ambient temperature no exceeding sixty both motors have identical info.
The motors possess better enclosure, degree of safety IP44 for typical site condition, and IP54 for metallurgical issue.
Motor’s rated voltage and frequency is 380V, 50HZ.

1. Brief-time obligation type (S2)
Operation of continuous load throughout a offered time, less than that essential to attain thermal equilibrium, followed by a rest and de-energized period of enough duration to re-establish equipment temperature within 2 deg K of the coolant.
2. Intermittent periodic responsibility type (S3)
A sequence of equivalent obligation cycles, every single which includes a time period of operation at continuous load and a relaxation and de-energized interval but the procedure interval are so limited that it is not enough for the device to achieve thermal equilibrium In this responsibility kind, the cycle is such that the commencing recent does not substantially influence the temperature rise.
3. Intermittent periodic responsibility kind with starting up (S4)
A sequence of similar duty cycles, every single which includes a considerable interval of starting, a period of procedure of continual load and a relaxation and de-energized period, but the operation period are so quick that it is not adequate for the equipment to get to thermal equilibrium.
four. Intermittent periodic responsibility variety with electric braking (S5)
A sequence of equivalent obligation cycles, every consisting of a interval of starting, a time period of operation at constant load and a relaxation and de-energized interval, but the operation period are so short that it is not adequate for the device to reach thermal equilibrium.
