INITIAL DESIGN – Thermal Operating Conditions of a Solenoid

BACKGROUND

An initial design is created to satisfy Thermal Condition #1 – 140C Ambient and the minimum magnetic force requirement of 6.25 N across a 7mm stroke. The design process is not covered in the case study. The 3D design is imported into Solenoid System’s Virtual Development Platform for magnetic analysis.

This design satisfies the force requirements at the Maximum Ambient Temperature of 140C with the Minimum Supply Voltage of 9.8 V. The design needs to be analyzed for the other two thermal conditions to verify that the force requirements are still satisfied.
