Abstract
A terminal board includes an attachment portion engageable with an end cap and defines an attachment plane that is substantially parallel to an end plane defined by the end cap, and a first terminal portion adapted to receive a first terminal wire. The first terminal portion defines a first terminal plane that intersects the end plane to define an included angle. The included angle is between about 40 degrees and 80 degrees.

A terminal board for an electric machine having an end cap defining an end plane, a first winding operable at a first voltage, and a second winding operable at a second voltage different from the first voltage, the terminal board comprising:
- an attachment portion engageable with the end cap and defining an attachment plane that is substantially parallel to the end plane;
- and
- a first terminal portion adapted to receive a first terminal wire, the first terminal portion defining a first terminal plane that intersects the end plane to define an included angle, the included angle being between about 40 degrees and 80 degrees.
A terminal board for an electric machine having an end cap defining an end plane, a first winding operable at a first voltage, and a second winding operable at a second voltage different from the first voltage, the terminal board comprising:
- an attachment portion engageable with the end cap and defining an attachment plane that is substantially parallel to the end plane;
- a voltage adjustment portion coupled to the attachment portion;
- a voltage adjustment member coupled to the voltage adjustment portion and movable between a first position and a second position to switch the motor from the first winding to the second winding;
- and
- a lock member coupled to the voltage adjustment member and operable to emit an audible sound when the voltage adjustment member is moved from the second position to the first position.
An electric machine comprising:
- a rotor;
- a stator including a first winding and a second winding, the rotor positioned adjacent the stator and rotatable in response to the application of a voltage to one of the first winding and the second winding;
- a housing surrounding at least a portion of the stator and including an end cap that defines an end plane;
- a terminal board coupled to the end cap and including a first terminal portion and a second terminal portion;
- a voltage adjustment portion formed as part of the terminal board and defining a voltage adjustment plane that is not parallel to the end plane;
- and
- a voltage adjustment member coupled to the voltage adjustment portion and movable between a first position in which the first terminal portion and the second terminal portion are electrically connected to the first winding, and a second position in which the first terminal portion and the second terminal portion are connected to the second winding.
