Abstract
A connector structure 10 is provided for powering an electric motor 19. The connector structure 10 includes a connector body 12; a low speed terminal 14 in the body; a high speed terminal 16 in the body; and a ground terminal 18 in the body. The ground terminal and the high-speed terminal are constructed and arranged to be coupled directly to the motor. The low speed terminal, the high speed terminal and the ground terminal are constructed and arranged to be coupled to a source of electrical power to power the motor. A resistive element 20 is coupled between the low speed terminal and the high-speed terminal. A shield member 26 houses the resistive element. The shield member is coupled directly to the connector body. Electrical power to the motor may be by controlled by selectively energizing the low speed terminal, the high speed terminal, or both the low speed terminal and high speed terminal so as to operate the motor at two different speeds.
