    摘要: A system and method are described for performing a mapping between persistent data objects and a database. For example, a method according to one embodiment of the invention comprises determining whether an attribute having a generic type is an instance of a persistent class; and if the attribute is an instance of a persistent class, then mapping the attribute to a discriminator column holding the type associated with the attribute and further mapping the attribute to a reference column holding a key associated with the attribute.

    摘要: A stator for an electric motor has a stator core, a winding and a housing enclosing the stator core and winding. The stator core has a yoke and a plurality of poles extending inwardly from the yoke. The winding formed by coils wound about the poles of the stator core. The housing grips the stator core and has at least one inwardly deformed portion that retains the stator core in the housing and prevents rotational movement of the stator core relative to the housing. A method of producing the stator is also disclosed.

    摘要: According to a first aspect the electric motor comprises the following components: a first stator member with n1 teeth, a second stator member with n2 teeth, and a third stator member with n3 teeth; a first connecting element that is in contact with the first and the third stator member, and a second connecting element that is in contact with the second and the third stator member. A tooth of the third stator member is arranged between a tooth of the first stator member and a tooth of the second stator member and n3 is greater than the sum of n1 and n2. According to a second aspect the stator of the electric motor comprises a first stack of sheet metal pieces that are joined to each other and a first stator plate. The stator plate is welded to the narrow sides of said sheet metal pieces.
