Abstract
An electromagnetically actuate machine balancer including a plurality of peripherally placed magnetic circuits and a power driver which selectively interrupts the magnetic flux through the circuits, thereby moving unbalanced rotors in a desired manner to compensate for machine unbalance.
Claims14
An apparatus for unbalance compensation comprising:
- (a) means for estimating unbalance;
- (b) a plurality of movable rotors, each having a plurality of peripherally mounted magnets, said magnets generating a plurality of magnetic fields;
- (c) a plurality of pole plates, stationary with respect to the moveable rotors, which cooperatively separate said plurality of moveable rotors, said plurality of pole plates receiving said plurality of magnetic fields;
- and
- (d) driver means for generating an electromagnetic field which selectively interrupts said plurality of magnetic fields so as to move said rotor.
An electromagnetically actuated rotating machine unbalance compensator comprising a pole plate having a plurality of peripherally spaced notches;
- a rotor having a plurality of peripherally spaced permanent magnets, said permanent magnets interacting with said notches to form a plurality of electromagnetic circuits;
- and generation means for producing a substantial short pulse of electromagnetic energy, effective to interrupt said plurality of electromagnetic circuits so as to cause said rotor to move.
A method of balancing a machine comprising the steps of:
- (a) movably coupling a first member to said machine;
- (b) placing a plurality of magnets in said first member, said plurality of magnets forming a certain magnetic field;
- and
- (c) generating at least one pulse of electromagnetic energy of a substantially short duration, thereby, at least in part, causing an interruption of said certain magnetic field, effective to move said first member to a predetermined location.
A method of balancing a machine comprising the steps of:
- (a) movably coupling a first member to said machine;
- (b) placing a plurality of magnets in said first member, said plurality of magnets forming a certain magnetic field;
- (c) providing a second member;
- (d) forming at least one reticule upon said second member, said at least one reticule receiving one of said plurality of magnets;
- and
- (e) interrupting said certain magnetic field, effective to move said first member to a predetermined location.
