Title: Controlling brushless motor commutation
Inventor: Jason Genz
IPC: H02P27/08
Filed: 2022-03-21
Abstract: A method of commutation control of a brushless DC (BLDC) motor uses a controller to control the BLDC motor using a modified six-step commutation. The method adds six intermediate steps that overlap the six-step commutation. Each of the six steps overlap with preceding and following steps, resulting in six additional intermediate steps in which all three phases are active. By doubling the number of steps, current and torque will vary less over time compared with current solutions without increasing the size or changing the design of the motor. The motor is controlled using overlapped commutation by controlling first high-side and first low-side switches corresponding to a first phase of the motor; controlling second high-side and second low-side switches corresponding to a second phase of the motor; and controlling third high-side and third low-side switches corresponding to a third phase of the motor; wherein during at least one step of the overlapped commutation, the first, second, and third phases of the motor are active. The method may be used for a tool, for example, motorized ratchet wrenches, drills and drivers.

Abstract: A method and system for managed pressure well cementing based on deep wellbore cement slurry system simulation. The method comprises the following steps: simulating a hydration reaction of wellbore cement slurry on the basis of basic data and well cementing data of an operating well; calculating in real time the bottom hole pressure in a well cementing process on the basis of the simulation; and adjusting the amount of opening of a choke manifold in order to control wellhead back pressure, such that formation pore pressure < bottom hole pressure < formation fracture pressure. The system comprises a computer-readable medium having a preset program stored thereon, the above method being able to be implemented when the preset program is executed. Bottom hole pressure can be calculated in real time by means of simulating physical or chemical reaction processes of a cement slurry system in a well cementing process, and wellhead pressure is controlled by means of adjusting a choke manifold, such that the bottom hole pressure is constantly maintained in the safe operation window range for a formation, thus preventing the occurrence of complex accidents such as well kicks, gas channeling, or leakage.

Title: A hydraulic plasma stone blaster probe
Inventor: HAJAR ZAREYI SE DEHI ZADEH
IPC: H01H1/48
Filed: 2021-10-06
Abstract: The present disclosure relates to an improvement and optimization tool for a plasma stone blaster instrument. In an embodiment, the instrument comprises a co-centric high voltage earth electrode, an insulator as the electric separator, and an earth electrode so that the parts of the earth electrode and high-voltage electrode have the ability to adjust the distance between them for different applications. The instrument is supported by a high voltage energy storage and a related generator, which create an electric arc in an even environment by creating a high voltage between two electrodes and passing the high current. The electric arc created by the high voltage electrode and earth electrode are in a fluid environment with controlled dimensions, which can create strong shockwaves and destroy the surrounding solid environment. The arrangements of these two electrons and the distance adjusted between them, as well as, created mechanical resistance and the system is designed for decreasing impacts lead to the increased lifetime of the probe against impacts. Also, the instrument limits the fluid volume and increases the pressure transferred to the environment. One of the advantages of the present disclosure is the use of fluid material with favorable density and elastic coefficient, which improves the efficiency of the process as an optimum energy transporter.
