Stepper motors for abrasive dust environments
An
Empire Magnetics product story
Edited by the Engineeringtalk editorial team
Jul 8, 2002
Empire Magnetics has developed a range of abrasive dustproof stepper motors.
Empire Magnetics has developed a range of abrasive dustproof stepper motors.
These motors have been designed to overcome the challenges of abrasive dust such as grinding debris, carbide powder, glass particles and mineral components that destroy seals and bearings, causing motors to fail.
They are available in industry standard 23, 34 and 42 frame sizes.
These motors are pressure rated to 15lb/in2 to lock out contamination.
Features include O-ring seals to eliminate dust leaks at potential penetration points, housing seals with a shaft slinger and seal to prevent abrasive dust from entering the bearing and motor insulation for operation at 145C.
Abrasive dustproof motors are currently being used in a number of applications, including fibre optics manufacturing, carbide tool manufacturing, and as part of a powdered metal forming press, among others.
