摘要： A power tool has a motor with end caps secured by cold forming to the motor. The end caps include bearings retained in the end cap by deformation of the end cap. The motor includes an armature shaft which is staked to retain laminates as well as a retainer on the shaft. Also, a pinion gear with a shoulder which limits movement of the shaft in the motor. A fan is on the motor armature which is secured by an adhesive which changes color during assembly. The motor also includes a demagnetization member which increases resistance to demagnetization due to elevated temperature, as well as armature reaction field.

摘要： A cylinder/magnet assembly for a field of an electric machine, such as a stator of a brush type motor or a rotor of a brushless motor, alternator or generator, is formed by inserting pre-formed magnets on a cylinder having anchors. Plastic is molded around the magnets and anchors to secure the magnets to a surface of the cylinder. In another aspect of the invention, magnets are inserted into magnet pockets of an assembly ring. The assembly ring is inserted into a cylinder and plastic molded around the assembly ring and magnets to secure the assembly ring and magnets to the cylinder. In another aspect of the invention, magnets are inserted in a first assembly ring which is then inserted in one side of a cylinder. A second assembly ring is inserted into the other side of the cylinder and mated to the first assembly ring. Plastic is molded around the assembly rings and magnets to secure them to the cylinder. In another aspect of the invention, magnets are inserted into magnet receiving pockets of a cylinder and plastic molded therearound. In another aspect of the invention, the north and south poles of a cylinder and magnet assembly have unequal distribution angles. In another aspect of the invention, the north and south poles a cylinder and magnet assembly have unequal numbers of magnets. In another aspect of the invention, the anchors are also formed as flux spreaders. In another aspect of the invention, flux spreaders are disposed on inner surfaces of the magnets of each pole of a cylinder and magnet assembly. In another aspect of the invention, the foregoing aspects are used in a stator of a motor. In another aspect of the invention, such a stator is used in a power tool.
