Abstract
Abstract An axial flux induction electric machine (10) having a stator (11) and a rotor (14), the rotor (14) is supported on a shaft (15) which supports the rotor (14) so as to be movable between an operative position and a brake position wherein a brake means engages the rotor (14) to inhibit rotation thereof.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
150 words
An axial flux induction electric motor (10) having a stator (11) with a radial face with radially extending slots (13) through which field windings (12) extend, a rotor (14), coaxial with said stator and having a radial face extending generally parallel to the radial face of said stator, a shaft (15) rotatably supporting said rotor (14) for rotation about the longitudinal axis of the shaft (15), said rotor (14) being movable longitudinally of said axis from an operative position wherein the radial face of said rotor (14) is positioned adjacent the radial face of said stator (11), and a brake position wherein the radial face of said rotor (14) is spaced further from the radial face of said stator (11) relative to said operative position, and brake means (21) to engage said rotor (14) when said rotor (14) is located in said brake position, so as to inhibit rotation thereof.
Claim 2
Dependent Claim
150 words
An axial flux induction electric motor (10) having a stator (11) with a radial face with radially extending slots (13) through which field windings (12) extend, a rotor (14), coaxial with said stator and having a radial face extending generally parallel to the radial face of said stator, a shaft (15) rotatably supporting said rotor (14) for rotation about the longitudinal axis of the shaft (15), said rotor (14) being movable longitudinally of said axis from an operative position wherein the radial face of said rotor (14) is positioned adjacent the radial face of said stator (11), and a brake position wherein the radial face of said rotor (14) is spaced further from the radial face of said stator (11) relative to said operative position, and brake means (21) to engage said rotor (14) when said rotor (14) is located in said brake position, so as to inhibit rotation thereof.
Claim 3
Dependent Claim
62 words
The motor (10) of claim 1 further including a flange (22) fixed to said shaft (15) so as to be movable therewith, and wherein said stator (11) is provided with a brake surface (21), providing said brake means, adapted to engage said flange (22) when said rotor (14) is moved to said brake position, to thereby inhibit rotation of said rotor (14).
Claim 4
Dependent Claim
52 words
The motor (10) of claim 1 further including a housing (31) containing said rotor (14) and stator (11) and from within which said shaft (15) projects, brake pad means (32) mounted on said housing (31) and positioned to engage said rotor (14) when said rotor (14) is moved to said brake position.
Claim 5
Dependent Claim
18 words
The motor (10) of claim 1 further including means (23) biasing said rotor (14) to said brake position.
Claim 6
Dependent Claim
22 words
The motor (10) of claim 4 wherein the means (23) biasing said rotor (14) to said brake position is a spring (23).
