With the development of the market of electric vehicles, the issue of efficient battery charging becomes even more urgent. Thanks to the continuous increase in the level of development of electronics, new opportunities appear to create power electrical equipment with previously unattainable characteristics. For these purposes, a universal algorithm for fast charging of LiFePO4 batteries been developed. It assumes the fastest charging of the battery without damage due to overheating or overcharging. The algorithm includes several main parts: the algorithm of initial temperature testing, the algorithm of initial trickle charging, the main current charging algorithm, the algorithm of permanent temperature testing, the main voltage charging algorithm, algorithm of permanent temperature testing, the algorithm for final trickle charging. The efficiency of the fast battery-charging algorithm studied by mathematical modeling. Computer modeling carried out using open source software.

In this paper, we consider a new design of synchronous motor with salient poles rotor and all coils placed on the stator. This design, uses a laminated silicon steel rotor, which is not so expensive as a rotor with super strong permanent magnets. This design of machine eliminates copper rings on the rotor and brushes which is used in regular synchronous motors, and eliminates disadvantages involved with these arrangements. In an earlier publication, authors considered the opportunity realization of synchronous mode operation in the machine with salient pole rotor and DC stator excitation. Now, we consider the new synchronous mode operation with individual DC excitation of each the alternative current (AC) windings for realization the first, second and third phase synchronous machines. In theoretical basics of analyses and design of synchronous motors we pay more attention to the single-phase motor because it is the basis for design polyphase synchronous machines.

DC motors are the most controllable electrical machines but more complicated for fabrication, in comparison with induction motors having simplified design but more complicated for control. Regular DC motor contain excitation (field) coil on the stator and armature coil on the rotor. Armature coil connected with external voltage source by a mechanical commutator with brushes. This arrangement complicates fabrication of DC machine, increases its cost, lowered reliability, and demands regular maintenance. Electromagnets inside of the stator increase dimensions of DC motor. In DC motor with salient pole rotor, there are no coils on the rotor, and mechanical commutator with brushes is eliminated, and eliminated all disadvantages connected with this arrangement. In this paper, we consider the new version of DC machine with DC stator excitation in compare with presented earlier. The difference is in using individual coil excitation for each armature coil, placed on the stator.

Linear electric motors designed on the basis of permanent magnets have disadvantage. It is caused by nonlinear distribution of a magnetic flux density around the cylindrical permanent magnet. Therefore, the motors should be designed with the high level reserve power. It lids to increase of mass - dimensional parameters of a motor. In addition, it complicates a control system of an electric drive on base of the linear motor. These disadvantages are eliminated by using, offered by authors, of three-zoned permanent magnetic structures. Using the three zone magnetic structures on basis Nd-Fe-B permanent magnets allows reducing weight - dimensional parameters of the linear motor. In this paper is considered design technique of creation the tree zone magnet structure. As an example, it was designed linear electrical motor (actuator) for diesel speed electronic controller. Prototype electronic speed controller was build and tested.

Heavy-duty trucks and self-propelled platforms are widely spread for the purpose of transportation of heavy and bulky loads. Power units of these vehicles consist of synchronous electric generators (alternators) driven by diesel engines. The generator supplies electricity to each motor-wheel of the vehicle and to all its systems. Alternators are also used in cars' and trucks' electric systems to supply their electric and electronic devices (e.g., headlights, safety systems, etc.). Substantial reserves of production and quality improvement of such alternators are hidden in their tests technique improvement. In this paper, the software is designed for mobile and stationary test stands of the alternators. The software was created using "LabVIEW" development system. It is designed to be used with "National Instruments®" hardware.

The brushless DC motors with permanent magnets are used primarily in law power applications. There are no limits on weight and motor dimensions in considered motors with DC stator excitation. Brushless series connected machine with DC stator excitation do not have rotor coils. Field coil and armature coils are mounted in the stator. Armature windings are connected to DC voltage source trough power transistors commutator. Power transistors are controlled by reflective optical sensors in function of rotor position. In the report, the new principle design of the motor with DC stator excitation is considered. The new principle of design supposes individual excitation for each of the armature phase. Such approach gives an opportunity to design electrical machine with any number of armature phases spaced in phase from each other. In series connected DC machines, the field winding is connected in series with the armature winding.

The internal combustion engine gradually concedes the positions of traction unit. The electric drive including the electric motor, electro-generator, and diesel installation, comes on its change. The vector pulse control system of the wound rotor induction motor drive can be one of the perspective variants of such electric drive. The speed control of wound rotor induction motor with thyristor converter, assembled on base of three phase bridge circuit, is considered in report. The entrance circuits of the converter are connected to AC generator through motor stator windings, and converter output circuit (on the side of the dc voltage) connected to a two rotor windings connected in series. The third rotor winding can be connected in parallel or remain free. The stator magneto-motive force is created by switching thyristors. Magneto-motive force is rotating discretely with a step of 60 degrees.

Controller of the high pressure fuel pump position rod drive is the inner loop of the diesel crankshaft rotation frequency control. To make a high fast of the loop of regulating of the diesel crankshaft rotation frequency the inner loop is to be faster. Under such conditions there is a necessity to take into account the discreteness of the work of the voltage converter of the actuator. In the report the questions of design of the fuel pump rod position control are considered on the basis of the method of state-space in the discrete domain. Design includes receiving of the linear difference equations describing of the open loop with the impulse width modulation. The main feature of the description offered in the report is in the direct using the system of the differential equations to get the linear system of the linear difference equations without the step of making up the analytical solution of the differential equations.
