Filed:

Nov 22, 1999

Appl. No.:

9/444738

Inventors:

Wayne A. Pengov - Chardon OH
Douglas L. Carr - Chardon OH

Assignee:

Tridelta Industries, Inc. - Mentor OH

International Classification:

H02K 1906

US Classification:

310166

Abstract:

A switched reluctance motor comprised of a stator having a plurality of evenly spaced, radially oriented, like stator poles that define a gap between adjacent stator poles. Windings for three phases are wound about the stator poles wherein a stator pole of a first phase is disposed circumferentially between a winding and an associated stator pole of a second phase and a winding and an associated stator pole of a third phase. A rotor is mounted for rotation relative to the stator. The rotor has an even number of rotor poles, the rotor poles being dimensioned such that when one of the phases is energized, the rotor poles operatively interact with the energized stator poles such that the motor moves from a first state wherein half of the rotor poles are magnetically coupled to a like number of the stator poles to a second state wherein all of said rotor poles are magnetically coupled to a like number of stator poles.

International Classification:

US Classification:

310166

Abstract:

A switched reluctance motor having a stator with a plurality of radially oriented stator poles. Windings for three phases are wound about the stator poles wherein a stator pole of a first phase is disposed circumferentially between a winding and an associated stator pole of a second phase and a winding and an associated stator pole of a third phase. A rotor is mounted for rotation relative to the stator. The rotor has a wide rotor pole and a narrow rotor pole. The rotor poles are distributed on the rotor wherein a narrow rotor pole is disposed to each side of a wide rotor pole in a direction of rotation. The rotor poles are dimensioned such that the energization of one of the phases causes the wide rotor pole to interact with a first energized stator pole to induce a first torque on the rotor and to produce a first predetermined angular rotation of the rotor, and thereafter causes the narrow rotor pole to interact with a second energized stator pole to induce a second torque on the rotor and to produce a second predetermined angular rotation of the rotor.

International Classification:

A61M 3/02

Abstract:

Fluid management systems are disclosed that include software-controlled, electro-mechanical devices used in combination with single-use or multi-use tubing sets. Functions of the fluid management systems can include fluid pressurization, fluid warming, fluid deficit monitoring (including flow-based and weight-based), suction, fluid collection, and fluid evacuation (including indirect-to-drain and direct-to-drain options). The systems can be configured based on the surgical environment (e.g., operating room or physician office) as well as other user needs and/or preferences.
