Abstract
A pole piece for a torque motor includes two separate arcuate members and first and second diametrically opposed attachment portions formed as a single piece of material. Each arcuate member extends in opposite directions from the first attachment portion and following a generally circular path defining a perimeter of the pole piece and meeting each other at the second attachment portion. The arcuate members are devoid of any holes or apertures.
Claims19
The method of constructing a torque motor, comprising:
- providing at least one pole piece formed from a single piece of material and at least partially by two arcuate members extending in opposite directions from a first attachment portion of the pole piece and following a generally circular path defining a perimeter of the pole piece, wherein a cross-section of the arcuate members are devoid of any holes or apertures and meet each other at a second attachment portion diametrically opposed from the first attachment portions of the pole piece, a top surface and a bottom surface of each arcuate member extends vertically and circumferentially away from the first attachment portion.
A pole piece for a torque motor, wherein the pole piece is a single piece of material formed at least partially by two separate arcuate members, each extending in opposite directions from a first attachment portion of the pole piece and following a generally circular path defining a perimeter of the pole piece, wherein a cross-section of the arcuate members are devoid of any holes or apertures and meet each other at a second attachment portion diametrically opposed from the first attachment portions, of the pole piece, a top surface and a bottom surface of each arcuate member extends vertically and circumferentially away from the first attachment portion.
An apparatus for a torque motor, comprising:
- a lower pole piece;
- an upper pole piece;
- and
- one or more permanent magnets extending between the lower pole piece and the upper pole piece, wherein the permanent magnets are configured to support the upper pole piece in use;
- wherein each of the lower pole piece and the upper pole piece is a pole piece is a single piece of material formed at least partially by two separate arcuate members, each extending in opposite directions from a first attachment portion of the pole piece and following a generally circular path defining a perimeter of the pole piece, wherein a cross-section of the arcuate members are devoid of any holes or apertures and meet each other at a second attachment portion diametrically opposed from the first attachment portions of the pole piece, a top surface and a bottom surface of each arcuate member extends vertically and circumferentially away from the first attachment portion.
