maxon EC Size 5 Sterilizable Brushless Motors
maxon EC Size 5 is a miniature brushless motor family developed for high-speed, sterilizable drive applications. This review treats it as a legacy selection and uses an identified manufacturer configuration to separate motor capability from current orderability.
Review Summary
EC Size 5 remains relevant when assessing an installed miniature high-speed mechanism or planning its replacement. The identified sensorless 50 W example 448824 can no longer be ordered through the manufacturer page. A new design therefore needs a currently supported motor and a fresh mechanical, thermal and sterilization qualification.
Family envelope Size 5 denotes a 0.5-inch motor diameter Example part 448824; sensorless, sterilizable, 50 W type-power designation Example nominal voltage 48 V Example nominal operating point 69,400 rpm and 7.17 mNm Example no-load / maximum speed 73,500 / 90,000 rpm; different rating conditions Example nominal current 1.21 A Example configuration status Manufacturer states that 448824 can no longer be ordered Selection boundary Hall-sensor and sensorless versions require configuration-specific controller selection Applications and Industries
