Method of forming a power tool |
| 摘要 |
A method for forming an armature for an electric motor includes: securing a lamination stack having slots therein on an armature shaft, securing a commutator on one end of the armature shaft, winding magnet wires in the slots in the lamination stack and securing ends of the magnet wires to the commutator, the magnet wires having armature lead wires that extend from the slots to the commutator; and molding plastic over the magnet wires to encase at least the armature lead wires in plastic. Alternatively and/or additionally, plastic is molded over the magnet wires to retain them in the slots and to support the armature lead wires and prevent them from vibrating when the armature rotates during operation. |

1. A method for forming an armature for an electric motor, comprising:
securing a lamination stack having slots therein on an armature shaft; securing a commutator on one end of the armature shaft; winding magnet wires in the slots in the lamination stack and securing ends of the magnet wires to the commutator, the magnet wires having armature lead wires that extend from the slots to the commutator; and molding thermally-conductive plastic over the magnet wires to encase at least the armature lead wires in thermally-conductive plastic. |
