YKK 3KV three.3KV 4.6KV 6KV 10KV Medium Substantial Voltage Marine rescue equipment Maritime provides Motors 3 Period Induction Motors 185~10000kw
Y,YKS,YKK Series high voltage a few-period asynchronous motors (Body No.355-1000) mounting proportions and tolerance are coincident with China regular GB755, CZPT CZPTal committee standard IEC34-oneand machinery-profession specifications JB/T/7593 JB/T1571.one and many others.
The grade of defense for outer include is in accordance with GB4942 and IEC34-5 common, there are four grades IP23, IPW24, IP44 and IP54. The IP23 grade can update to IP44(Tube Ventilation) in accordance the customer’s request. Also give other protecting quality specifically.
The cooling method is in accordance to the GB/T1993 and IEC34-six common . There are three sorts of cooling strategy IC01,IC611 and IC81W. Also we can give other cooling approach according the client request.
The structure and mounting model is IMB3 (horizontal foot mounted) is in accordance with GB997 and IEC34-7 (IM code) requirements.
The body is created of metal plate becoming welded up into form of square tank form with mild bodyweight and agency rigidity .
Stator is a outer-push-assembly composition, the stator winding is a F grade insulation, at the winding’s finish part currently being firm banded.
The entire stator has been dealt with with VPI engineering to make stator with a strong physique and great electrical and humidity resistance.
The rotor can be developed into two modes casting aluminum and copper bar manner. Casting aluminum rotor is casted with pure aluminum. Copper-bar rotor is manufactured by copper bars wedges in the slots, then at the bar’s each conclude to be soldered with a finish-ring by reliable soldering technologies. At the end of process, it need to be immersed in lacquer after to improve the integration.
Either rolling or sleeve bearing may possibly be adopted, the protection grade of bearing is IP54. For the rolling bearings method, the rolling bearing have to be lubricated with grease, and the motor have to have oil-inlet and oil-exhaust devices, motor can also be non-quit oil injection. For the sleeve bearing mode, the oil offer method for the bearing must be ready by buyers. But the effectiveness for sleeve bearing motor will be permitted a little lessen with respect of the specialized information desk and that is permissible in according with the relative stipulates of the common issued by Ministry of Device Creating.
The main terminal box is created by Germany DIN regular. The grade of safety is IP54. The terminal box for normal motor is located at the correct aspect (Viewed from axle extension). Also can be mounted at left aspect in accordance customer’s need. The outlet hole of terminal box can encounter up, down, proper and left four directions. There is a unbiased grounded unit in the main terminal box.
Usually the motors axle is solitary extension method, the key is a planar crucial method. We also can offer double shaft extension mode according customer’s necessity.
We can install temperature measurements in stator and bearings. And put in interior place heaters for moisture defending for the duration of stoppage.
The Implication of the symbol
By GB4831 stipulation, the motor’s kind is composed of solution image and specification image in sequence.
The product image is demons dealt with by motor collection symbols, its implication is as following:
Y———squirrel-cage rotor a few-phase asynchronous motor.
YKS——Enclosed squirrel-cage rotor 3-stage asynchronous motor with air-water cooler
YKK—— Enclosed squirrel-cage rotor a few-phase asynchronous motor with air-air cooler
The specification image is composed of centre height, iron-core duration amount and quantity of poles.
- Frame measurements: 355-1000
- Rated output: 185-8000kW
- Insulation course: F
- Degree of defense: IP54 /IP55
- Enclosure: IC611
- Mounting: Horizontal
- Rotor: Squirrel cage
- CZPT: Rolling bearing or sleeve bearing

This motor can be processed by the anticorrosion anti-mould-proof procedure to derive outside (W) and outdoor corrosion defense (WF) motors. Substantial effectiveness, energy preserving, low vibration, little dimensions, mild weight, trustworthy overall performance and straightforward set up and routine maintenance. The body is made of steel plate currently being welded up into type of sq. tank shape with gentle excess weight and organization rigidity. Stator is an outer-press-assembly composition. The stator winding is F grade insulation at the winding’s end portion getting agency banded. The total stator has been handled with VPI technologies to make stator with a robust physique and great electrical and dampness evidence. The rotor can be produced into casting aluminum rotor or copper bar rotor. The copper cage rotor manual bar and end ring are welded by intermediate frequency, and the copper information bar diameter groove is treated with reliable technologies to make it have high trustworthiness.
Excellent for driving all kinds of general machinery, these kinds of as water pump, admirer, compressor, crusher and and so forth.
