Abstract
Abstract An apparatus for isolating a stepper motor from an associated mounting frame, with the motor having a circular locating step on a mounting face. An insert is used to increase the height of the locating step, to enable an isolation member to be positioned on the locating step, and yet provide a second locating step to be used in locating and isolating the motor relative to the frame.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
104 words
An apparatus comprising: a stepper motor having a mounting flange, a mounting face, and a circular locating step located on said mounting face, with said circular locating step having a first dimension; a first member mounted on said circular step and shaped to provide a second dimension greater than the first dimension of said circular locating step; a frame having a mounting hole therein; an isolation member mounted on said first member and shaped to isolate said first member and said mounting flange from said frame; and said frame having retaining means thereon retaining said mounting flange thereto with said isolation member positioned therebetween.
Claim 2
Independent Claim
104 words
An apparatus comprising: a stepper motor having a mounting flange, a mounting face, and a circular locating step located on said mounting face, with said circular locating step having a first dimension; a first member mounted on said circular step and shaped to provide a second dimension greater than the first dimension of said circular locating step; a frame having a mounting hole therein; an isolation member mounted on said first member and shaped to isolate said first member and said mounting flange from said frame; and said frame having retaining means thereon retaining said mounting flange thereto with said isolation member positioned therebetween.
Claim 3
Dependent Claim
27 words
The apparatus as claimed in claim 1 in which said first member is made of polycarbonate and said isolation member is made of an isolation thermoplastic material.
Claim 4
Independent Claim
143 words
An apparatus comprising; a stepper motor having a mounting flange, a mounting face, and a circular locating step located on said mounting face; an insert mounted on said circular locating step, with said insert being shaped to provide a circular locating step; a frame having a mounting hole therein and also having an annular shoulder extending into said mounting hole; and an isolation member being mounted on the circular locating step of said insert, with said isolation member being shaped to provide a circular locating step, with said circular locating step of said isolation member being mounted in said mounting hole and abutting against said annular shoulder; said isolation member also having a portion corresponding in shape to said mounting flange; and said frame having a retaining means thereon retaining said mounting flange thereto with said portion of said isolation member positioned therebetween.
Claim 5
Independent Claim
143 words
An apparatus comprising; a stepper motor having a mounting flange, a mounting face, and a circular locating step located on said mounting face; an insert mounted on said circular locating step, with said insert being shaped to provide a circular locating step; a frame having a mounting hole therein and also having an annular shoulder extending into said mounting hole; and an isolation member being mounted on the circular locating step of said insert, with said isolation member being shaped to provide a circular locating step, with said circular locating step of said isolation member being mounted in said mounting hole and abutting against said annular shoulder; said isolation member also having a portion corresponding in shape to said mounting flange; and said frame having a retaining means thereon retaining said mounting flange thereto with said portion of said isolation member positioned therebetween.
Claim 6
Dependent Claim
17 words
The apparatus as claimed in claim 3 further including means securing said isolation member to said insert.
Claim 7
Independent Claim
179 words
An apparatus comprising: a stepper motor having a mounting flange, a mounting face, and a circular locating step located on said mounting face, with said circular locating step extending a first distance from said mounting face; an insert having a tubular portion and a flange portion, with said tubular portion surrounding said locating step of said stepper motor and having a length extending beyond said first distance to a second distance from said mounting face, and with said flange portion contacting said mounting face; a frame having a mounting hole therein and also having an annular shoulder extending into said mounting hole; an isolation member having a tubular portion and a flange portion, with said tubular portion of said isolation member surrounding said tubular portion of said insert and extending along the length thereof; securing means for securing said isolation member to said insert; said isolation member having a portion corresponding in general shape to said mounting flange; and said frame having retaining means for retaining said mounting flange thereto with said portion of said isolation member positioned therebetween.
Claim 8
Independent Claim
179 words
An apparatus comprising: a stepper motor having a mounting flange, a mounting face, and a circular locating step located on said mounting face, with said circular locating step extending a first distance from said mounting face; an insert having a tubular portion and a flange portion, with said tubular portion surrounding said locating step of said stepper motor and having a length extending beyond said first distance to a second distance from said mounting face, and with said flange portion contacting said mounting face; a frame having a mounting hole therein and also having an annular shoulder extending into said mounting hole; an isolation member having a tubular portion and a flange portion, with said tubular portion of said isolation member surrounding said tubular portion of said insert and extending along the length thereof; securing means for securing said isolation member to said insert; said isolation member having a portion corresponding in general shape to said mounting flange; and said frame having retaining means for retaining said mounting flange thereto with said portion of said isolation member positioned therebetween.
Claim 9
Dependent Claim
