Abstract: A motor has a stator substantially encapsulated within a body of thermoplastic material; and one or more solid parts used in the motor either within or near the body. The thermoplastic material has a coefficient of linear thermal expansion such that the thermoplastic material contracts and expands at approximately the same rate as the one or more solid parts. In another aspect, a motor for a hard disc drive comprises at least one conductor, at least one magnet, at least one bearing and a shaft; and a monolithic body of thermoplastic material substantially encapsulating the at least one conductor. The bearing is either encapsulated in the thermoplastic material, housed in a hollow cylindrical insert encapsulated in the thermoplastic material, or secured in a bore formed in the body of thermoplastic material. The motor has improved shock resistance.

Abstract: A motor has a stator substantially encapsulated within a body of thermoplastic material. A plurality of different motors are made by encapsulating different stators using the same mold tool. The stators may differ with respect to one or more of the following: i) the number of turns of wire per winding, ii) the number of poles, iii) the diameter of the stator, and iv) the thickness of the stator The stators are then used to build motors with different characteristics. The process produces benefits associated with development time and cost for new motor configurations.
