Abstract

An electric motor includes a housing, and a stator arranged within the housing. The stator includes a plurality of terminal leads. A terminal box is mounted to the housing, and a terminal block assembly arranged within the terminal box. The terminal block assembly includes a terminal block portion having a first plurality of terminals and a terminal block section that is distinct from the terminal block portion. The terminal block section including a second plurality of terminals. The terminal block portion is configured and disposed to be spaced from the terminal block section in the terminal box. The plurality of terminal leads is electrically connected to corresponding ones of the first and second pluralities of terminals.

Claims

1. An electric motor comprising:

a housing;

a stator arranged within the housing, the stator including a plurality of terminal leads;

a terminal box mounted to the housing; and

a terminal block assembly arranged within the terminal box, the terminal block assembly including a terminal block portion including a body portion having a base portion including at least one mounting member secured in the terminal box through a first mechanical fastener and a terminal surface portion supporting a first plurality of terminals and a terminal block section that is distinct from the terminal block portion, the terminal block section including a body section having a base section including at least one mounting element secured in the terminal box through a second mechanical fastener and a terminal surface section supporting a second plurality of terminals, the terminal block portion being configured and disposed to be spaced from the terminal block section in the terminal box, the plurality of terminal leads being electrically connected to corresponding ones of the first and second pluralities of terminals.

2. The electric motor according to claim 1, further comprising:

a grounding bar secured to one of the at least one mounting member and the at least one mounting element, the grounding bar being electrically connected to the housing.

3. The electric motor according to claim 1, further comprising:

a plurality of linking members electrically connecting select ones of the first plurality of terminals and the second plurality of terminals, the plurality of linking members establishing a desired electrical configuration for the plurality of terminal leads.

4. The electric motor according to claim 1, further comprising:

a terminal passage formed in the terminal box, the terminal passage including a first side portion, a second side portion, a third side portion, and a fourth side portion that collectively define an opening leading into the housing, the terminal block portion being arranged along the first side portion and the terminal block section being arranged on the third side portion opposite the terminal block portion.

5. An electric motor terminal block assembly comprising:

a terminal block portion including a body having a base portion having at least one mounting member including at least one opening configured to receive a first mechanical fastener and a terminal surface portion, the terminal surface portion supporting a first plurality of terminals; and

a terminal block section that is distinct from the terminal block portion, the terminal block section including a base section including at least one mounting element having an least one opening configured to receive a second mechanical fastener and a terminal surface section, the terminal surface section supporting a second plurality of terminals, the terminal block portion being configured and disposed to be spaced from the terminal block section in a terminal box.

6. The electric motor terminal block assembly according to claim 5, further comprising:

a grounding bar secured to one of the at least one mounting member and the at least one mounting element.

7. The electric motor according to claim 5, further comprising:

a plurality of linking members electrically connecting select ones of the first plurality of terminals and the second plurality of terminals, the plurality of linking members establishing a desired electrical configuration for an electric motor.
