Motor mounting device
First Claim
1. A device for securing an electric motor within an outer housing defining at least one radial opening, comprising a longitudinally convoluted annulus substantially equal in length to the stator of the electric motor and having at least one longitudinal plate affixed to the outer surface of said annulus, said plate defining at least one radial opening engageable by a fastener passing through such one opening in such outer housing.

Abstract
A device for mounting an electric motor stator within an outer housing is disclosed. The mounting structure comprises a longitudinally convoluted hollow metal cylinder having three longitudinal plates attached at 120° intervals to its outer wall. The cylinder is sized to provide an interference fit with the stator and the convolutions permit sufficient diametral expansion to facilitate assembly and tight retention of the stator when placed within the cylinder. The cylinder/stator assembly is retained in the outer housing by a plurality of bolts which pass through the outer housing and engage threaded openings in the longitudinal attachment plates secured to the outer cylinder surface.

2. A device for securing a stator of an electric motor having a plurality of longitudinal ribs on its outer surface in an outer housing comprising, in combination, a longitudinally convoluted cylinder substantially equal in length to the motor stator and having at least one longitudinal attachment plate affixed to the outer surface of said cylinder, said attachment plate including at least one threaded opening engageable by a threaded fastener passing through an opening in the outer housing, whereby said fastener engages said threaded opening in said attachment plate and secures said cylinder to the outer housing.
- 3. A device for securing a stator of an electric motor having a plurality of longitudinal parallel projections on its outer surface within an outer housing comprising, in combination, a cylinder having a plurality of longitudinal parallel convolutions engaging the plurality of projections on the outer surface of the motor stator, said cylinder being substantially equal in length to the motor stator and having at least two longitudinal attachment plates affixed to its outer surface, said attachment plates being spaced about said cylinder and each including at least one threaded radially disposed opening engageable by a threaded fastener, said fastener passing through a radial opening in the outer housing and engaging said threaded opening in said attachment plates, whereby said cylinder and the electric motor stator are secured within the outer housing and whereby relative rotation between the electric motor stator and the housing is prevented.

6. A device for securing a stator of an electric motor having a plurality of longitudinal parallel projections on its outer surface within an outer housing comprising, in combination, a cylinder having a plurality of longitudinal convolutions engaging the plurality of projections on the outer surface of the motor stator, said cylinder being substantially equal in length to the motor stator and having three longitudinal attachment plates affixed to its outer surface, said attachment plates being equally spaced about said cylinder and each including two threaded radially disposed openings engageable by threaded fasteners, said fasteners passing through radial openings in the outer housing and engaging said threaded openings in said attachment plates, whereby said cylinder and the electric motor stator are secured within the outer housing and whereby rotation of the electric motor stator relative to the housing is prevented.
- 7. A device for securing an electric motor within an outer housing defining a plurality of openings comprising, in combination, a longitudinally convoluted annulus having a plurality of attachment plates secured to the outer surface of said annulus, and fastener means for engaging said attachment plates through such openings in such outer housing.
