摘要： Systems and methods are provided for controlling two or more linear generators each operating according to a repeated behavior to constitute a cycle. A control system utilizes control circuitry to determine a desired phase offset between operation cycles of a first linear generator and a second linear generator of the two or more linear generators. During operation, an actual phase offset between the first linear generator and the second linear generator is determined. The control circuitry of the control system is used to modify the operation of at least one of the first linear generator or the second linear generator to achieve the desired phase effect.

摘要： A load adaptive linear electrical generator system is provided for generating DC electrical power. The electrical generation system includes one or more power generation modules which will be selectively turned on or off and additively contribute power depending on the DC power demand. Each power generating module includes a pair of linear electrical generators connected to respective ones of a pair of internal combustion piston based power assemblies. The piston in the internal combustion assembly is connected to a magnet in the linear electrical generator. The piston/magnet assembly oscillates in a simple harmonic motion at a frequency dependent on a power load of the electrical generator. A stroke limiter constrains the piston/magnet assembly motion to preset limits.

摘要： A free piston generator based on a rigid synchronous transmission system is provided, which belongs to the technical field of power energy. The present disclosure solves the problems of low power generation efficiency and low stability of the existing free piston generator. The free piston generator based on the rigid synchronous transmission system includes a first linear generator set, a second linear generator set, a rigid synchronous transmission assembly, two high-pressure cylinders arranged at two ends of the first linear generator set, and two low-pressure cylinders arranged at two ends of the second linear generator set. The combustion product is firstly subjected to first-stage expansion in the high-pressure cylinder and is then subjected to second-stage expansion in the low-pressure cylinder, which effectively increases the energy utilization in exhaust gas, also increases the expansion work, and further improves the thermal efficiency and the power generation efficiency of the free piston generator. By means of the rigid synchronous transmission assembly, high-pressure pistons and low-pressure pistons are always kept in stable phase operation, so as to avoid the problems of wall-impingement and insufficient pressure of compressed air due to the phase mismatching.

摘要： Systems and methods for providing power to devices at a well site employ a linear alternator to generate power at a well site. The linear alternator is mounted on a pump at the well site and uses the up-and-down motion of the pump to generate power. The pump may be a nodding donkey head pump or other sucker rod pump mechanisms that operate based on linear vertical motion. The linear vertical motion drives a linear rotor back and forth through a linear stator to induce current in the linear alternator. This allows the linear alternator to convert a portion of the mechanical work performed by the pump into electrical energy that can be supplied to the devices. In some embodiments, the pump-mounted linear alternator can be equipped with a position sensor to directly measure a vertical position of the pump as the alternator travels up and down with the pump.

摘要： An integrated linear generator system includes, for example, a generator assembly, a control system, a frame system, an exhaust system, an intake system, a cooling system, a bearing system, one or more auxiliary systems, or a combination thereof. The generator system is configured to generate power, as controlled by the control system.

摘要： To propose a new power generator using the movement of a linear magnetic body and to further improve a conventionally-proposed power generator. A configuration is provided including a tubular frame, a freely-moving magnetic body group that is arranged at the inner side of the tubular frame and that is obtained by integrating two or more magnetic bodies while homopolar bodies are opposed to each other, a coil provided on the tubular frame to have an interval to the outer periphery of the freely-moving magnetic body group and that is configured to alternately have a reversed winding direction, and an output line for outputting electric power from the coil. In a configuration in which the freely-moving magnetic body groups slide relative to each other in a coil axial direction to generate power, a transmission means is provided that is coupled to at least any one tip end of the freely-moving magnetic body group in a substantial axial direction, and power is generated in accordance with the movement of the transmission means.
