YKK Medium-Sized High-Voltage Three-Phase Asynchronous Motors

Features:
1) YKK series medium-sized motors (H355-630) are our new products
2) Its output range, dimension of installation and electric performance are in
    conformity with correlative national GB755-2000 and relative IEC standards
3) The motor adopts compact box structure and wielding-jointed steel plate for
    its frame
4) There is closed air to air coolers on top of the stator frame
5) The stator is so constructed as the stator core is stacked and assembled with
    coils to form an individual assembly which is then put into the stator housing
    rigidly supported and braced at the end portion
6) During processing, the coils undergo several turn and turn pulse voltage tests
    and voltage endurance test to ground and vacuum pressure impregnated with
    solventfree varnish
7) Squirrel rotor is made of pure aluminum and adopts advanced casting technique
8) Depending on the output and speed of the motor, rolling bearing or sleeve
    beating is used
9) Other voltage / frequency and protection class can also be provided upon order
    request
10) High efficiency, low noise, slight vibration, reliable operation, convenient
     installation and maintenance
11) YKK series 10kV motors are applicable for driving various types of universal
     machines, such as compressors, pumps, crushers, cutting machine tools,
     transportation equipment and other mechanical equipment
12) Used as prime mover in mines, mechanical industry, petroleum and chemical
     industry and power plants
13) If they are to be used to drive fans, coal-grind machines, rolling mills,
     windlasses, relevant technical information should be provided when special
     consideration will be given to the motors so as to ensure reliable operation
     of motors
