Stepper Motor For Vehicle Propulsion By Direct Wheel Drive

View page
US Patent:
6836035, Dec 28, 2004
Filed:
Jun 3, 2003
Appl. No.:
10/452005
Inventors:
Joseph P. Pawletko - Endwell NY, 13760
International Classification:
H02K 3706
US Classification:
310 49R, 310 67 A, 310 68 B, 310254, 180 655
Abstract:
The present invention provides an external rotor stepper motor consisting of four individual, independently controlled, co-planar stepper motors optimized for vehicle direct wheel drive applications. The innovative design eliminates the need for bifilar coil winding, each of the motors coils being single conductor, each coil being wound in the same direction throughout the entire motor. Each of the four independent motors is simultaneously energized. Because adjacent, outside coils of adjacent motors are simultaneously energized at the same polarity, there is substantially no energy wasting cancellation of magnetic flux. Carefully chosen radially spacing of the four independent, co-planar motors also eliminates substantially all flux interaction between the motors. Because similar coils of the four motors are all connected in parallel, the net inductance presented driver circuits is minimized. This yields fast rise time pulses and improved efficiency through minimized reactance of the motor.

View page
US Patent:
51534720, Oct 6, 1992
Filed:
Jul 19, 1991
Appl. No.:
7/732557
Inventors:
John P. Karidis - Ossining NY
Gerard Mc Vicker - Wappingers Falls NY
Joseph P. Pawletko - Endwell NY
Ralph R. Comulada - Rock Tavern NY
Assignee:
International Business Machines Corporation - Armonk NY
International Classification:
H02K 4100
US Classification:
310 13
Abstract:
An actuator for use in positioning a probe. The actuator has a magnet, two C-shaped cores on opposite sides of the magnet, an electromagnetic coil, and an armature movably connected with the cores. The armature has a projecting face located over portions of both pole faces for each core for the entire range of motion of the armature. The armature is primarily retained with the cores by magnetic attraction by the magnet. The actuator also has an armature position sensor which can include either an optical sensor or a magnetic sensor. A test probe is mounted to the armature which can be preloaded and have dual springs to prevent scrubbing and increase contact force with an object being tested.

Rotary Stepper Motor And Method Of Operation

View page
US Patent:
40299775, Jun 14, 1977
Filed:
Nov 26, 1975
Appl. No.:
5/635535
Inventors:
Hi Dong Chai - Binghamton NY
Joseph Paul Pawletko - Endwell NY
Assignee:
International Business Machines Corporation - Armonk NY
International Classification:
H02K 3700
US Classification:
310 49R
Abstract:
A three phase rotary stepper motor of the variable reluctance type comprises a rotor and an annular stator having three pairs of diametrically opposed stator poles wound with bifilar windings. The stator windings are connected so that opposed poles are energized as a pair having the same polarity. The bifilar winding is connected so that pole pairs are energized with either polarity. A two phase energization scheme is used which causes adjacent poles of two pole pairs to have opposite polarity, while the third pole pair is magnetically neutral. Every three steps of the sequence the magnetically neutral pole pair is magnetized with the reverse polarity.

Method Of And Apparatus For Controlling Gray Scale While Printing On Charge Sensitive Recording Mediums

View page
US Patent:
44132697, Nov 1, 1983
Filed:
Nov 23, 1981
Appl. No.:
6/323843
Inventors:
Joseph P. Pawletko - Endwell NY
Charles R. Pigos - Endicott NY
Assignee:
International Business Machines Corporation - Armonk NY
International Classification:
G01D 1506
H04C 1534
US Classification:
346154
Abstract:
A method of and apparatus for controlling gray scale in the charge sensitive media of a matrix printer by using constant amplitude write pulses. Their use is intended to overcome registration problems caused by constant movement of the charge sensitive recording media during the actual print cycle. This control method and apparatus are implemented by varying, as a function of the desired intensity of one or more pixels to be printed, the effective write time and the number of constant amplitude pulses applied to any one or more of a plurality of print electrodes over a complete write cycle. The normal printer write cycle is divided into a number of subdivisions, that number being a function of the maximum permissible allowable error that can be perceived by a human eye. Further, the write pulse waveforms used are derived so that there is not more than one write cycle subdivision difference at either termination point of any intensity pixel printed therewith.

Positioning Apparatus And Movement Sensor

View page
US Patent:
52911128, Mar 1, 1994
Filed:
Dec 7, 1992
Appl. No.:
7/986269
Inventors:
John P. Karidis - Ossining NY
Gerard McVicker - Wappingers Falls NY
Joseph P. Pawletko - Endwell NY
Assignee:
International Business Machines Corporation - Armonk NY
International Classification:
B25J 914
US Classification:
3185681
Abstract:
A movement sensor for a multi-bar positioner includes a first section having a curved corner reflector (76), a second section (70), and a third section with an analog position-sensitive-photodiode (84). The second section (70) has three LEDs (72, 82) and four photodetectors (74). Two of the LEDs (72) and the four photodetectors (74) face a first direction towards the corner reflector (76). The third LED (82) faces a second direction, different than the first direction, towards the position-sensitive-photodiode (84). The second section can be mounted on an arm of the positioner and used in conjunction with the first and third sections to determine movement or position of that arm.

Low Inertia High Torque Variable Reluctance Motor

View page
US Patent:
44750510, Oct 2, 1984
Filed:
Aug 27, 1982
Appl. No.:
6/412453
Inventors:
Hi D. Chai - San Jose CA
Joseph P. Pawletko - Endwell NY
Assignee:
International Business Machines Corporation - Armonk NY
International Classification:
H02K 3700
US Classification:
310 49
Abstract:
A high performance, low cost variable reluctance stepper motor has an integral structure with a ring and a plurality of aligned salient pole members. A plurality of teeth are located on the face of each pole member. Windings are disposed on alternate ones of the pole members and a high impedance means isolates the pole members from one another. A rotor with a plurality of teeth and a plurality of holes disposed thereon coacts with the pole members and is moved in a step fashion by the sequential energization of the windings. The flux generated by the energization of the windings is confined to a short path and coupling to the remainder of the structure is negligible. Recesses positioned symmetrically around the structure also serve to enhance flux splitting and reduce adjacent flux coupling.

Linear Actuator With Multiple Closed Loop Flux Paths Essentially Orthogonal To Its Axis

View page
US Patent:
48109142, Mar 7, 1989
Filed:
Mar 26, 1987
Appl. No.:
7/031321
Inventors:
John P. Karidis - Ossining NY
Joseph P. Pawletko - Endwell NY
Assignee:
International Business Machines Corporation - Armonk NY
International Classification:
H02K 4100
US Classification:
310 12
Abstract:
Alternately stacked radial-pole stator and spacer laminations provide a simple linear actuator, in which alternating layers form magnetic teeth in the axial direction. The spacer laminations are non-ferromagnetic or dimensionally spaced from the flux path. The stator laminations have radially extending pairs of poles, forming a central hole which may be filled and ground smooth along with the spacers, forming smooth pole faces upon which the armature may slide. Flux paths are coplanar with stator laminations, thus making each lamination completely independent. Electromagnetic force increases linearly as stator laminations are added. The stacked stator laminations have pole faces each having a finite pole face flux capacity; related armature rings can be mounted on a nonmagnetic support tube and made as light as possible so long as each ring is of sufficient cross-sectional area to carry half the pole face flux capacity. Tubular armatures provide maximum rigidity as a function of mass and permit the use of a stationary rod armature support for the tube armature. The support rod may be ferromagnetic to carry some of the flux, thereby further reducing the cross-section and the mass required for each ring.

Electrolytic Printing Apparatus Including Preheating Pressure Pad Therefor

View page
US Patent:
43359671, Jun 22, 1982
Filed:
Mar 3, 1981
Appl. No.:
6/240332
Inventors:
Joseph P. Pawletko - Endwell NY
Assignee:
International Business Machines Corporation - Armonk NY
International Classification:
B41J 302
US Classification:
400119
Abstract:
A preheating pad and assembly for electrolytic printing apparatus is provided. The pad is adjustably mounted to the write head of the printer for movement normal to the recording medium used therein. The pad is fabricated from a ceramic chip and includes a resistive heating element that is protected by a thin bottom layer provided for that purpose. It is joined to an insulated carrier arm by a spring which serves to electrically and mechanically couple the pad and the print head. The biasing effect made possible by the spring allows the pad contact pressure with the recording medium surface to be tuned or adjusted as required. In operation, the pad's position is adjusted to force moisture deposited by an applicator on the surface of the recording medium to penetrate the recording medium's surface layer while simultaneously heating both the surface layer's constituent materials and the fluid being driven therein.
