New IntelliGen variable speed brushless blowers offer the capability to customise for specific end-user requirements.
They are ideally suited for applications in a wide range of industries, including data storage, medical/biotech, semiconductor, automation, and many others.
Series GM8000 gearmotors are available with a range of 11 standard reduction ratios from 6.3:1 to 1803.6:1; Series GM9000 gearmotors offer 12 ratios from 5.9:1 to 4732.5:1; and Series GM14000 gearmotors feature four ratios from 5.9:1 to 218.4:1.
Armatures are skewed to minimise magnetic cogging and windings are resin-impregnated for greater reliability in incremental motion applications.
Two-pole permanent magnet stators are constructed with ceramic magnets enclosed in heavy-gauge steel return rings.
Diamond-turned commutators promote maximum brush life.
Optional customisation components include cartridge brush assemblies, encoders, modified shafts, shaft-mounted pulleys, ball bearings, electromechanical brakes, and RFI suppression, among others.
