Y2, YKK, YKS Large Voltage AC Squirrel Cage Asynchronous Induction Motor
one. EPT introduction
YKK-series (2Kv~11Kv) squirrel-cage three section asynchronous motor, is creating on the sophisticated EPT in the country. The security diploma of the motor is of IP23(according toGb4942.one), and the cooling method is IC01(in accordance to GEPT/T1993).
The motors has a great deal of benefits this kind of as heigEPT efficiency, enerty-preserving, minimal noise and vibration ,ligEPT weigEPT and reilable efficiency. THey are straightforward for installation andmaintenance. The motor has high insulation class and moistureproof potential.
The motor is employed to travel different mechanical equipments these kinds of as blowers, pumps, crushers, storkremoing EPTs and other equipments. It can provide as the prime movers in coEPTs, mechanical EPT, EPTEPTs and a variety of EPT EPTrprises.
two. EPTrief Construction
The motor adopts compacted box construction, welding-jointed steel plate forits frame, ligEPT fat, rigid in construction, there is closed air to air coolers on the stator frame convenient for set up and servicing.
Stator winding adopts F course insulation and its conclude adopts organization binding. The EPT stator adopts solvent-free of charge varnish Vacuum force impregnation(VPI) to make sure the stator has superb electrical home and humidity resistance.
Rotor is produced of solid aluminium or copper bar. Aluminium rotor is made 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 speed. EPTearing safety quality generally is IP44. If the motor’s defend grade boosts, so does the berings’. Rolling bearing adopts iubricating gresse and its grease charger and discharger can be charged or discharged with no halting the motor.
The junction box is of IP54 safety grade and it is usually mounted on the motor’s rigEPT aspect(viewed from shaft extension finish.) It is also can be mounted on the remaining side and its shops have four optional orientations(up, down, still left or appropriate.) Divided grounding device is accessible in main junction box, too.
3. Functioning problems and performance
a) THe rated EPT source is 6KV/50HZ, 10KV/50HZ.
b) The insulation course is F, the safety degreeis IP44 or IP54.
c) HeigEPT above sea amount does not exceeding 1000 meters.
d) HeigEPT environmental temperature lt40 ordmC, most affordable environmental temperature:rolling bering gt-15 ordmC.silding bering gt5 ordmC.
e) The ambient air relative humidity does not exceed 95% and the mean regular monthly bare minimum temperature of existing month does not exceed twenty five ordmC
f) The deviation in between EPT voltage and rated voltage is much less than5%.
g) Rated frequency:50Hz 1%.
h) Responsibility type:continuous obligation variety S1.
i) Cooling approach is IC611.
OrEPTrequirement:
You should show the motor variety, rated output, rated voltage, rated frequency, synchronous pace, EPT Mark, mounting type, security grade, cooling method, rotation course(look at from the shaft extension side), using setting (indoor /outside the house).
