Zusammenfassung:Systems and methods for securing coils of magnet wire to a support core in a linear motor that may be used, for example, in an ESP. In one embodiment, a hollow member such as a cylindrical metal tube is provided as a support core which is adapted to receive a mover of the linear motor. Coils of magnet wire are positioned at the exterior of the support core (e.g., wound around the core). An outer layer of shrink-wrap material is placed around the support core and coils and is heated, causing it to shrink and conform to the coils and the support core. The shrink-wrap material provides pressure against the coils which holds them securely against the support core. This assembly may then be positioned within a stator housing and secured to form the stator for the linear motor.
