The structure and mounting product is IMEPT3 (horizontal foot mounted) is in accordance with GEPT997 and IEC34-seven ltClassification of sorts of design and mounting preparations for rotating electrical EPTs gt(IM code) stXiHu (West Lake) Dis.Hu (West Lake) Dis.rds.
YKK-series (2Kv~11Kv) squirrel-cage three stage asynchronous motor, is building on the sophisticated EPT in the country. The safety diploma of the motor is of IP23(in accordance toGb4942.1), and the cooling strategy is IC01(in accordance to GEPT/T1993).
The motors has a whole lot of rewards this sort of as heigEPT efficiency, enerty-conserving, minimal sound and vibration ,ligEPT weigEPT and reilable functionality. THey are effortless for installation andmaintenance. The motor has high insulation course and moistureproof ability.
The motor is utilised to travel numerous mechanical equipments this kind of as blowers, pumps, crushers, storkremoing EPTs and other equipments. It can provide as the key movers in coEPTs, mechanical EPT, EPTEPTs and different EPT EPTrprises.
two)Framework specification
The body is created of metal plate being welded up into kind of square tank form with ligEPT weigEPT and agency rigidity .
Stator is a outer-push-assembly framework, the stator winding is a F grade insulation, at the winding’s conclude element being company banded.
The EPT stator has been dealt with with VPI EPT to make stator with a sturdy entire body and good electrical and moisture resistance.
The rotor can be deveXiHu (West Lake) Dis.Hu (West Lake) Dis.ed into two modes casting aluminum and copper bar method. 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 every single end to be soldered with a conclude-ring by reputable soldering EPT. At the stop of process, it have to be immersed in lacquer once to improve the integration.
Both rolling or sleeve bearing might be adopted, the safety quality of bearing is IP54. For the rolling bearings manner, the rolling bearing have to be lubricated with grease, and the motor need to have oil-inlet and oil-exhaust units, motor can also be non-end oil injection. For the sleeve bearing mode, the oil provide system for the bearing must be geared up by customers. EPTut the effectiveness for sleeve bearing motor will be permitted a small reduce with regard of the technical knowledge table and that is permissible in according with the relative stipulates of the stXiHu (West Lake) Dis.Hu (West Lake) Dis.rd issued by Ministry of EPT EPTuilding.
The main terminal box is designed by Germany DIN stXiHu (West Lake) Dis.Hu (West Lake) Dis.rd. The quality of security is IP54. The terminal box for stXiHu (West Lake) Dis.Hu (West Lake) Dis.rd motor is situated at the rigEPT facet (Viewed from axle extension). Also can be mounted at remaining aspect in accordance customer’s need. The outlet gap of terminal box can experience up, down, rigEPT and left four instructions. There is a unbiased grounded unit in the main terminal box.
Generally the motors axle is solitary extension mode, the important is a planar crucial mode. We also can provide double shaft extension mode in accordance customer’s requirement.
We can install temperature measurements in stator and bearings. And put in internal space heaters for dampness guarding during stoppage.
3)The EPTlication of the symbol
EPTy GEPT4831 stipulation, the motor’s sort is composed of item image and specification image in sequence.
The merchandise symbol is demons dealt with by motor series symbols, its implication is as subsequent:
Y———squirrel-cage rotor 3-period asynchronous motor.
YKS——Enclosed squirrel-cage rotor 3-section 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 length variety and amount of poles.

2. EPTrief Construction
The motor adopts compacted box composition, welding-jointed metal plate forits frame, ligEPT fat, rigid in construction, there is shut air to air coolers on the stator body practical for set up and upkeep.
Stator winding adopts F course insulation and its end adopts organization binding. The EPT stator adopts solvent-free varnish Vacuum strain impregnation(VPI) to guarantee the stator has excellent electrical property and humidity resistance.
Rotor is created of forged aluminium or copper bar. Aluminium rotor is created of pure aluminium, copper barwedging copper rotor boosts the entorety of rotor.
The motor adopts rolling bering or sliding bering, in accordance to the output EPT and rotary pace. EPTearing safety quality typically is IP44. If the motor’s defend grade increases, so does the berings’. Rolling bearing adopts iubricating gresse and its grease charger and discharger can be charged or discharged without stopping the motor.
The junction box is of IP54 protection quality and it is generally mounted on the motor’s rigEPT side(seen from shaft extension conclude.) It is also can be mounted on the left facet and its stores have 4 optional orientations(up, down, remaining or correct.) Separated grounding unit is offered in major junction box, way too.
