Motor for a power tool |
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.
