How to Calculate the Optimal Diameter of a Pole Tip and Winding Parameters for DC Valve Electric Magnets with Round Pole Tips

摘要

Numerical expressions for determining the pole tip diameter that will secure the highest electromagnetic moment are obtained. How different factors influence the optimal diameter of the pole tip is estimated. A formula for calculating the pole tip optimal diameter in a wide range of variation by considering the mode of magnet operation and power supply, permissible overheating, winding relative height, and armature angular position is given. A procedure for determining the winding parameters at the stage of electromagnet design is specified.
