56results about How to "Minimize torque" patented technology

A rotary valve is disclosed having a rotor and stator that utilizes at least one compression spring to provide contact between the rotor and stator. The spring(s) is configured to oppose the pressure forces that urge the rotors and stators apart and reduce the amount of torque necessary to turn the rotors in the valve while preventing leakage from between the rotor and stator. The spring(s) may be positioned within the valve by a spring locating features.

A stabilized backpack comprises a hip suspension and a shoulder suspension. The hip suspension comprises vertical support rods pivotally attached to the hip belt and pack frame to allow motion of the wearer's hips without causing varying forces on the pack. The shoulder suspension comprises pulleys and cords attaching the shoulder straps to the pack so that the motion of the wearer's shoulders does not cause varying forces on the pack. The net effect is that a person can run with the pack, with heavy load, in rough terrain, with the pack staying relatively stable.

A starting system and method for starting a salient-poled-rotor electric motor having a stator with a plurality of spaced salient poles, a plurality of field coils of unchanging polarity, and a plurality of armature coils, wherein each field coil of the plurality of field coils at least partially overlaps an armature coil of the plurality of armature coils, and wherein variable excitement of the armature coils alternately creates a magnetic pole force in every other pole of the plurality of spaced salient poles of the stator. In such motors, the stator has a first position, wherein the rotor is in stasis with respect to the stator and torque between the rotor and the stator is substantially minimized, and a second position, wherein torque between the rotor and the stator is substantially maximized. A drive circuit provides current to the field coils and the armature coils. A start circuit is provided for regulating the drive circuit to vibrate the rotor to the second position. A current source is connectable to the drive circuit for variably exciting the armature coils to produce substantially continuous rotation of the rotor. A switch is provided for electrically engaging the start circuit with the drive circuit while the rotor moves from the first position to the second position, and for electrically engaging the current source with the drive circuit when the rotor reaches the second position.

A linear oscillating actuator system which is capable of canceling out the stator vibrations for driving a load with a minimum of vibrations. The system includes an oscillator carrying a permanent magnet as well as an output shaft for connection to the load. A stator assembly is incorporated within a housing and is configured to movably support the oscillator and to carry an electromagnet. The electromagnet generates a magnetic field which interacts with the permanent magnet to reciprocate the oscillator relative to the stator assembly in a linear path. A balancer is added to the system for canceling out undesired stator vibrations. The balancer are commonly supported to the stator assembly to be driven thereby in parallel with the oscillator. The balancer is configured to have a mass generally equal to that of the oscillator and to be devoid of any output member. Thus, the oscillator and the balancer are driven in a counter reciprocating manner, thereby keeping the stator assembly free from counter-vibrations and therefore driving the output shaft with a maximum output power.

Durability of a planetary gear set can be enhanced and noise can be reduced by utilizing a power transmitting apparatus for a hybrid vehicle that supports a planetary gear set in an axial direction and a perpendicular direction. In addition, because a parking gear is disposed on a second shaft, torque can be minimized when the vehicle is parked on a slanted road.
