MATRIX MOTOR, LLC - Fort Lee NJ

International Classification:

H01R 39/12

US Classification:

310232

Abstract:

This invention relates to a brushless slip ring using bearing for transmitting voltage and current between rotating rotor and stator. The invention relates to attaching a magnet to the slip ring to create a more stable rotor, eliminating sparks and erosions caused by the disconnection at times to the stator by enforcing a magnetic pull to the stator wall. In addition, a cooling-filtering system with synthetic oil can provide sufficient and constant clean lubrication.

Appl. No.:

7/930263

Inventors:

Chong Kyu Kim - Brooklyn NY

International Classification:

G09B 2308

US Classification:

434302

Abstract:

A hypersurface orbital model is presented that orbits a ball on a surface called a hypersurface. A stepper motor drive arrangement, with two-degrees of freedom, is used to change the hypersurface viewed by the ball as a function of time. System control is added to ensure that the ball will orbit in the proper orbit. Control consists of a stepper motor, a clock, a solenoid launcher and various logical circuits. Counters keep track of the period so that the exact rotational speed can be referenced to set the ball launcher.

A63B 22/00

Abstract:

An adjustable supine cycling machine is an apparatus that efficiently exercises and strengthens abdominal muscles. The apparatus targets the all of the abdominal muscles from all angles. As the user pedals, the user may retract or extend his or her legs and tilt his or her legs in order to activate all the muscles of the abdominal region. The apparatus includes a leg-exercising device, a support base, a lifting arm, and a linear actuator. A spherical bearing allows the tilt of the leg-exercising device. The leg-exercising device is preferably a cycling machine. The lifting arm pivots the leg-exercising device about the support base and is controlled by the linear actuator. The apparatus preferably applies resistance to the rotary movement of the leg-exercising device in order to strengthen the abdominal muscles. The resistance is adjusted by a control unit.

Assignee:

International Classification:

H02K 7/08
F16C 35/06
F16C 41/00

US Classification:

310425

Abstract:

In one embodiment, an electric motor includes at least three bearings. The ball bearing utilized in the three bearings may be sized based on benchmark surface areas associated with the ball bearing utilized in a conventional electric motor having two bearings. Moreover, a technique may be implemented to reduce the diameter at a point on the shaft where a backup or second bearing makes contact with the shaft. When the motor begins to operate, for example, at a first time, the at least three bearings together handle a the load coming through the motor. When the front-most bearing degrades to a predetermined point or fails, for example, at a second time, the load transitions from the front most bearing to the second or backup bearing in the front plate.

Abstract:

In one embodiment, a motor has a rotor with an approximated ellipsoid shape defined by a plurality of lattice lines and a plurality of lattice points. The motor has a matching stator that is configured to be utilized in conjunction with the approximated ellipsoid shaped rotor and to accommodate the approximated ellipsoid shaped rotor. The motor may also includes a housing unit configured to hold the matching stator that is utilized in conjunction with the approximated ellipsoid shaped rotor, and an enclosure lid configured to be used by the housing unit. The enclosure lid may be configured to hold the rotor having the approximated ellipsoid shape with a bearing.
