Abstract:
An apparatus comprising:a base having a tubular section;a stator extending around and at least partially enclosing said tubular section of said base;a rotor extending around and at least partially enclosing said stator and said tubular section of said base, said rotor being rotatable relative to said stator and said base under the influence of magnetic forces transmitted between said rotor and stator;a drive shaft connected with said rotor and extending into said tubular section of said base, said drive shaft being rotatable with said rotor relative to said stator and said base; andmeans for reducing transmission of vibration between said tubular section of said base and said stator;said means for reducing transmission of vibration includes a plurality of hollow metal members disposed between said tubular section of said base and said stator, said hollow metal members being resiliently deflectable under the influence of vibrations induced in said stator during rotation of said rotor relative to said stator.
