Method of making a coil molded into a magnetic stator

An unencapsulated bobbin-mounted coil is associated with a stator wherein the stator, in cooperation with other parts of a mold, define a mold cavity. Encapsulating material is injected through gates in one of the other mold parts into the defined mold cavity to encapsulate the coil and bobbin in th...

Summary:An unencapsulated bobbin-mounted coil is associated with a stator wherein the stator, in cooperation with other parts of a mold, define a mold cavity. Encapsulating material is injected through gates in one of the other mold parts into the defined mold cavity to encapsulate the coil and bobbin in their entirety, including attachments of the finish lead ends of the coil wire to bobbin-mounted electrical terminals that extend axially away from the bobbin and coil, except for distal end portions of the terminals. The process simultaneously joins the encapsulated coil and bobbin with the stator.
