LINEAR MOTOR SERIES: PART TWO
Magnet-Schultz of America (MSA) reveals the design and manufacturing techniques, performance, and functional characteristics of a Linear Motor.

DESIGN & MANUFACTURING TECHNIQUES
1. External Appearance: The Linear Motor (LM) assembly looks just like a conventional unidirectional electrohydraulic actuator. It includes a pressure tube, a removable coil, a coil nut and two external O-rings (one to help maintain friction between the retaining nut and coil, and one to help seal the tube-to-valve interface). See figures 1 and 2 below.
2. Internal Design & Manufacturing Techniques
(also depicted are the Linear Bearings which are used to reduce sliding friction)
PERFORMANCE & FUNCTIONAL CHARACTERISTICS
If you happen to have missed PART ONE of this series, which covers Linear Motor Concept, Genesis of Development, Background, and Physical Characteristics, we invite you to check it out.
We also invite you to look for PART THREE, which concludes the series with topics covering LM’s Theory of Operation, Empirical Test Results, and Additional Development Work.
We want to thank you for the time you have invested in learning about Linear Motors, and we encourage you to contact MSA with any questions you may have relating to your electromagnetic actuator needs.
