y series (ip23) middle-sized hv 3-phase asynchronous motor
introduction
parameters
product size
y series hv 3-phase asynchronous motor (frame size 355-710) is the latest product developed by this company with reasonable structure and advanced process. it is featured as high performance, energy-saving, low noise, small vibration, reliable operation, convenient installation and maintenance.
the power grade, mounting dimension and electrical performance of motor are compatible with states standard gb755-2000rating and performance of electrical rotating machine, concerning iec criteria and national industry standard jb/t7593 — 2007. the motor is used in environment with altitude no more than 1000 m, air temperature no more than 40 ℃, without heavy dust, corrosive or explosion gas. we can also produce motor applicable to humid tropics and plateau area as per ordering requirements.
the rated frequency of power is 50 hz, and rated voltage as 6000 v/10000v. we can also produce motor of 60 hz or other voltage as per ordering requirements.
the basic erection of motor is horizontal type with antapical born (imb3), and operation system as continuous (s1).
the motor uses box-type structure. the frame is made of steel sheet welding, featured with light weight and fair rigidity.
the stator uses external press fitting structure. the stator winding uses class f insulation material. the end has reliable fixing and binding. multiple inter-turn impulse voltage tests and grounding high-voltage holding tests have been conducted in manufacturing procedure. and it is processed with internationally advanced vacuum pressure impregnation (vpi) solvent free varnish equipment and process. thus the motor has excellent and reliable insulating property, fair mechanical strength and strong moisture-proof capacity.
the cage rotor uses cast aluminum and strip copper structures made of advanced and reliable casting process and welding technology with dynamic balance check to ensure stable and reliable operation of motor.
the bearings have antifriction bearings and sliding bearings to be determined by power and rotating speed of motor.y series is basic with protection grade of ip23. yks series (ip44 or ip54) may be derived as per ordering requirements.
main junction box is mounted at right (looking from shaft extension end) of motor usually, and left side available as per ordering requirements. the main junction box includes independent ground terminal.
the motors can be used to drive various general machines, e.g. compressor, pump, crushers, stock-removing machine, transport machines and other machines as prime engines in various industrial and mining enterprises, e.g. mines, engineering industry, petrochemical industry and power plant.purpose and technical requirements shall be indicated in ordering motor for ventilating fan, coal grinding mill, iron-rolling mill and hoister so as to use special design for reliable operation.
