Description
HyMD is a series of high-voltage asynchronous squirrel-cage motors of Japanese manufacture, intended for driving large machinery in the power, oil and gas, chemical, metallurgical and general industrial sectors. The series is designed for 3000 and 6000 V networks at 50 Hz, and for 3300 and 6600 V at 60 Hz; it covers designs from 2 to 12 poles. According to the catalogue, HyMD motor power with class F heating (temperature rise 105 K) is from 315 to 10,600 kW at 50 Hz and from 375 to 11,200 kW at 60 Hz; with the more conservative class B heating (rise 80 K) it is from 265 to 9,000 kW and from 315 to 9,500 kW respectively. This allows a motor to be selected with a thermal margin for heavy duty and long-term operation. The motors are produced in twelve frame sizes, from 400HM to 710HL (designations 400–710 with HM and HL indices); for each combination of power, voltage and pole count the catalogue specifies a particular frame size. Depending on the frame size and pole count, rolling bearings with grease lubrication or sliding bearings with forced oil supply are used. According to the catalogue the sound level is 90 dB(A) for four- to twelve-pole machines and 95 dB(A) for two-pole machines. Electromagnetic and mechanical calculations, as well as the analysis of the vibration response, are performed using CAD/CAE, which, according to the manufacturer, ensures high reliability, low noise and compactness. The manufacturer has produced electric motors since 1910 and has supply experience for 50 and 60 Hz networks; overall, its asynchronous motor range reaches a voltage of 13.8 kV and a power of 25,000 hp. Designs outside the catalogue tables are made to order. Typical applications: drives of pumps, fans and induced-draft fans of thermal power plants, compressors, blowers, mills and other auxiliary and process machinery; the motors can operate both from the mains and from medium-voltage frequency converters, for example the HIVECTOL-HVI series of the same manufacturer.
