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.
Key Specifications
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
Legacy miniature high-speed mechanisms and engineering assessments requiring a documented motor identity and a supported replacement path.
Medical instrument drives; high-speed miniature mechanisms; laboratory equipment
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.
