7.5 HP, 12,000 RPM air cooled Motor




The ME-421ASC is a 12,000 RPM, 7.5 horsepower 400Hz Electric Motor designed for use on the CD-510A and CD-510N 8-speed Core Drill gearboxes. It is an extremely reliable motor for heavy duty drilling.

An ME-420ASC Motor on the CD-510A gear box gives output speeds from 150 RPM to 1,600 RPM. CD-510N output speeds are slightly lower. All output speeds are listed on CD-510A and CD-510N catalog sheets.

A cast aluminum cover bolts over the output side of this motor to protect the gear and bearing from dirt when it is not mounted on the gearbox.
