ABSTRACT:
The field shell of an electromagnet is formed with angularly spaced flanges which define a magnetic pole and which also serve as a mounting hub for a coil assembly consisting of a bobbin and a multiple turn winding. Resilient fingers on the bobbin snap into openings in the flanges to hold the bobbin and the shell in assembled relationship. Tabs are located between and project inwardly from the flanges and are used to mount the shell in a fixed position.
