Специфической особенностью главного судового дизеля является наличие ограничительной характеристики, защищающей дизель от перегрузки по моменту. При экстремальных режимах крутизна винтовой характеристики возрастает, и автоматика, защищающая дизель от перегрузки, ограничивает диапазон режимов и величину движущей (или тормозящей) силы, создаваемой пропульсивным комплексом. В статье рассматриваются результаты имитационного моделирования экстремальных режимов движения судна – движение в ледяном поле и режим экстренного торможения.

&lt;p&gt;The permanent magnet AC motor trapezoidal (BLDC motor) is not strictly DC motor, which uses a pulsed DC fed to the stator field windings to create a rotating magnetic field. Therefore, the motor needs an electronic commutation to provide the rotating field. A pair of switches must be turned on sequentially in the correct order to energize a pair of windings. If the incorrect order is applied, then the BLDC motor will not operate properly. This paper presents a smart guideline to ensure that the order to energize a pair of windings is correct. To ensure the guideline, FPGA based a simp

In order to meet the construction needs of surface coalbed methane extraction holes, cable holes, and mine surface rescue holes, a multifunctional power head suitable for coalbed methane vehicle mounted drilling rigs has been developed. The power head adopts a dual speed hydraulic motor to drive the spindle rotation through a first gear reduction, with a compact structure, high transmission efficiency, large spindle diameter, wide range of speed and torque adjustment, and spindle braking function. It can be applied to various drilling processes such as air down the hole hammer, air lift revers

Abstract The main indicator of the quality of the cotton harvesting machine is the completeness of collecting the grown crop into the bin, which is usually 3-4% lower than the completeness of collecting spindles. This is because the remover of vertical-spindle machines does not fully remove the cotton bobbins from the spindles. Part of the cotton wound on the spindle is carried away into the working zone without being removed. This phenomenon is called “cotton carry-over”. According to previous authors, “Carry-over” reaches 3-4% of the spindle collection completeness. This happens because the

Abstract: The project is designed to develop a four quadrant speed control system for a DC motor. The motor is operated in four quadrants i.e. clockwise; counter clock-wise, forward brake and reverse brake. It also has a feature of speed control. The four quadrant operation of the dc motor is best suited for industries where motors are used and as per requirement as they can rotate in clockwise, counter-clockwise and also apply brakes immediately in both the directions. In case of a specific operation in industrial environment, the motor needs to be stopped immediately. In such scenario, this

The permanent magnet brushless DC motor (BLDCM) is typically controlled using the six-step commutation method, and the flux-weakening method is employed to enable the motor to operate at speeds higher than the base speed. Currently, it is considered that the weak magnetic angle range is 0-pi/3, while the range for deep weakening is pi/3-pi/2. In field-weakening control, a forward shift of the commutation point results in a circulating current flowing in the three-phase bridge of the inverter and the stator winding of the motor.

In a long historical perspective, the globalization of the economy is, no doubt, the future of the mankind. However, we should not overlook the contradiction that has dramatically intensified as a result of the 2008-2009 recession. This is the contradiction between globalization as an objective process with mostly positive effects and its model that is being implemented today (namely, the policy of globalization). Furthermore, we can propose a number of important arguments in favor of a statement that at the current state of affairs the globalization has exhausted itself. Nobody can exclude a
