Crane Motor

These series of metallurgical and crane three-period motor YZR, YZ with wound and squirrel cage rotor are specifically used to generate metallurgical crane and other comparable equipment with much better overload capacity and mechanical energy, for that reason, it is appropriate for short time responsibility or intermittent period obligation and equipments with frequent commencing and braking or distinctive vitration and affect.
The normal variety of energy output and mounting proportions are in comply with the reconmended common of IEC seventy two, the relation among selection of power output and mounting proportions are equivalent to common JEM1202 and West Germany normal DIN42681, so that most of them can be interchanged.
The motor can perform effectively when the altitude does not exceed 1000m.
There are two classes of F and H insulation, Class F is applicalbe to go well with temperature which great air does not exceed forty underneath normal situation, Course H is ideal for metallurgical sites when ambient temperature no exceeding sixty the two motors have same data.
The motors have far better enclosure, degree of defense IP44 for typical web site issue, and IP54 for metallurgical condition.
Motor’s rated voltage and frequency is 380V, 50HZ.

one. Short-time obligation sort (S2)
Operation of continual load in the course of a offered time, significantly less than that required to achieve thermal equilibrium, adopted by a relaxation and de-energized interval of adequate period to re-build machine temperature within 2 deg K of the coolant.
2. Intermittent periodic duty variety (S3)
A sequence of equivalent obligation cycles, each and every like a period of operation at consistent load and a rest and de-energized interval but the operation period are so brief that it is not ample for the device to reach thermal equilibrium In this duty sort, the cycle is this sort of that the commencing current does not considerably have an effect on the temperature rise.
3. Intermittent periodic obligation type with commencing (S4)
A sequence of similar obligation cycles, every including a important time period of beginning, a period of time of operation of constant load and a relaxation and de-energized time period, but the procedure period are so limited that it is not ample for the equipment to get to thermal equilibrium.
4. Intermittent periodic responsibility variety with electrical braking (S5)
A sequence of identical responsibility cycles, each consisting of a period of time of starting, a period of time of procedure at continuous load and a relaxation and de-energized period of time, but the operation period of time are so limited that it is not ample for the equipment to achieve thermal equilibrium.
