Abstract

An electric powerhead includes a housing including a mounting plate including a shaft opening and a plurality of first openings arranged in a standard horizontal shaft engine mounting pattern. The housing also includes a base including a plurality of second openings arranged in a standard horizontal shaft engine support pattern. The electric powerhead further includes an electric motor positioned within the housing, where the electric motor includes an output shaft that extends through the shaft opening of the mounting plate and where the output shaft is configured to rotate about an axis of rotation.

Claims (30)

1. An electric powerhead, comprising:

a plate including a shaft opening and a plurality of first openings arranged in a standard horizontal shaft engine mounting pattern;

a battery receptacle configured to receive a battery, the battery configured to be attachable and removable from the battery receptacle without the use of tools;

a base plate comprising a plurality of second openings arranged in a standard horizontal shaft engine support pattern; and

an electric motor supported by the base plate, wherein the electric motor includes an output shaft that extends through the shaft opening of the plate and wherein the output shaft is configured to rotate about an axis of rotation;

wherein the base plate is configured to be fastened to a mounting surface and to separate the electric motor and the battery receptacle from the mounting surface.

2. The electric powerhead of claim 1 , wherein the plurality of first openings comprises four openings.

3. The electric powerhead of claim 1 , wherein the plurality of second openings comprises four openings.

4. The electric powerhead of claim 1 , wherein a bottom surface of the base plate is spaced apart from the axis of rotation of the output shaft by a vertical distance equal to a standard horizontal shaft engine spacing.

5. The electric powerhead of claim 4 , wherein the vertical distance is between 4.1 and 4.2 inches.

6. The electric powerhead of claim 1 , wherein a diameter of the output shaft is equal to a standard small engine output shaft diameter.

7. The electric powerhead of claim 6 , wherein the diameter of the output shaft is between 0.74 and 0.79 inches.

8. The electric powerhead of claim 1 , wherein a length of the output shaft is equal to a standard small engine output shaft length.

9. The electric powerhead of claim 8 , wherein the length of the output shaft is between 1.9 and 2.4 inches.

10. The electric powerhead of claim 1 , wherein the battery is configured to provide electricity to the electric motor.

11. The electric powerhead of claim 10 , further comprising a plurality of battery receptacles supported by the base plate, wherein the battery is configured to be removably attached to one of the plurality of battery receptacles.

12. Outdoor power equipment, comprising:

an electric powerhead comprising:

a plate including a shaft opening and a plurality of first openings arranged in a standard horizontal shaft engine mounting pattern;

a base plate comprising a plurality of second openings arranged in a standard horizontal shaft engine support pattern;

a battery receptacle;

an electric motor supported by the base plate, wherein the electric motor includes an output shaft that extends through the shaft opening of the plate and wherein the output shaft is configured to rotate about an axis of rotation; and

a battery configured to be removably attached to the battery receptacle without the use of tools to provide electricity to the electric motor;

wherein the base plate is configured to be fastened to a mounting surface and further configured to separate the electric motor and the battery receptacle from the mounting surface.

13. The outdoor power equipment of claim 12 , wherein the plurality of first openings comprises four openings.

14. The outdoor power equipment of claim 12 , wherein the plurality of second openings comprises four openings.

15. The outdoor power equipment of claim 12 , wherein a bottom surface of the base plate is spaced apart from the axis of rotation of the output shaft by a vertical distance equal to a standard horizontal shaft engine spacing.

16. The outdoor power equipment of claim 15 , wherein the vertical distance is between 4.1 and 4.2 inches.

17. The outdoor power equipment of claim 12 , wherein a diameter of the output shaft is equal to a standard small engine output shaft diameter.

18. The outdoor power equipment of claim 17 , wherein the diameter of the output shaft is between 0.74 and 0.79 inches.
