(54) ЭЛЕКТРИЧЕСКАЯ МАШИНА(54) ELECTRIC MACHINE

Изобретение относитс к электрическим машинам и может применение при выполнении таких технологических операций, как, например, бурение скважин, создание вибраций.The invention relates to electric machines and can be used when performing such technological operations as, for example, drilling, creating vibrations.

Известна электрическа машина, содержаща статор, выполненный из отдельных частей, имеющих многофазные обмотки и расположенных по винтовой линии относительно оси ротора , и цилиндрический ротор с короткозамкнутой обмоткой 1.A known electrical machine comprising a stator made of separate parts having multi-phase windings and arranged in a helical line relative to the rotor axis, and a cylindrical rotor with a short-circuited winding 1.

Этот двигатель обеспечивает ,поступательное и вращательное движение ротора. Дл обеспечени нар ду с вращательным непрерывного возвратнопоступательного движени необходимо коммутирующее устройство, измен ющее пор док чередовани фаз. При этом направление вращени также из-менитс на обратное.This engine provides the translational and rotational motion of the rotor. In order to provide, along with the rotational continuous reciprocating movement, a switching device that changes the phase rotation order is necessary. In this case, the direction of rotation is also reversed.

Целью изобретени вл етс обеспечение возможности возвратно-поступательного движени без изменени направлени вращени .The aim of the invention is to provide the possibility of reciprocating motion without changing the direction of rotation.

Цель достигаетс тем, что обмотки каждых двух р дом расположенных частей статора имеют противоположный пор док чередовани фаз и противоположное направление винтовой линии, а обмотка ротора выполнена из чередующихс по окружности частей , в одних из которых стержни расположены п аллельно оси вращени ротора, в других - перпендикул рно k ней.The goal is achieved by the fact that the windings of each two rows of located parts of the stator have the opposite order of phase alternation and the opposite direction of the helix, and the rotor winding is made of parts alternating around the circumference, in one of which the rods are located parallel to the axis of rotation of the rotor, in others perpendicular to it.

На фиг. 1 и фиг. 2 изображена схематически предложенна электри10 ческа машина (развертка); на фиг. 3 - то же, вариант, продольный разрез; на фиг. 4 - то же, поперечный разрез; на фиг. 5 - взсшмное расположение статора и ротора, аксо15 нометри .FIG. 1 and FIG. 2 shows schematically the proposed electric machine (scan); in fig. 3 - the same, option, longitudinal section; in fig. 4 - the same, cross section; in fig. 5 - location of the stator and the rotor, accessories.

Статор электрического двигател выполнен из ;отдельных частей 1, которые охватывают ротор 2 и смещены одна относительно другой в осе20 вом направлении.The stator of an electric motor is made of separate parts 1, which cover the rotor 2 and are displaced one relative to the other in the axial direction.

Полюса частей 1 статора выполн ютс из шихтованного железа и располагсшзтс по винтовой линии относительно оси ротора, т.е. под углом The poles of the stator parts 1 are made of laminated iron and are located along a helical line relative to the rotor axis, i.e. at an angle

Claims

25 to its axis of rotation. A winding is laid in the grooves of the poles, preferably three phase. This moves the floor in the direction of the helix. The orientation in space and order of alternation of the phases of the windings of all even and odd parts is identical. The windings of each, the first two rows of located parts 1 of the stator have the opposite order of phase rotation and the opposite direction of the helix. The direction of the traveling half of the% is shown in FIG. 1 and FIG. By 2 arrows, the rotor 2 is a ferromagnetic body, preferably a circular cross section of the logo. The short-circuited rotor winding is made of alternating; c around the circumference of parts 3 and 4 "per 3 x rotor rotor windings are flat; The rotors are parallel to the axis of rotation of the rotor and are connected by short-circuiting rings 5, and in parts 4 the rods are perpendicular to the axis of rotation of the rotor and are connected by short-locking rings 6, the rotor 2 is mounted in bearings 7, which ensure its rotational and translational movement. ; Part 3 provides only the rotational movement of the rotor (F), and part 4 - the reciprocating motion of the rotor (F). The reciprocating motion of the rotor is provided as a result of parts 4 of the rotor falling at I at different times under the personally oriented statuses pa. In this case, the frequency of vibration will depend on the speed of rotation of the rotor. At the moment of time shown on fkg, 1, the rotor is simultaneously affected by the torque and the axial force directed to the right. Further rotation of the rotor brings the system to the position shown in FIG. 2, and the rotor will move to the left. The direction of rotation does not change. Continuous operation of the engine is ensured without the use of complementary switching equipment or other auxiliary devices. Thus, the proposed motor provides simultaneously rotational and reciprocating motion during continuous operation using the same stator pole system. Adjusting the frequency of its translational motion can be provided by adjusting the speed of rotation, therefore, without reducing the impact force. In addition, since during the presence of the rotor winding under the poles there is always a component of their relative motion along the field direction, the mode of the short curtain (at which the slip is equal to unity) is absent. The proposed engine also makes it possible to reduce the specific energy consumption and simplify the power supply system. An electric machine comprising a stator made of separate parts having multiphase windings and located along a helical line relative to the rotor axis, and a cylindrical short-winding rotor, characterized in that in order to enable the rotor to reciprocate without changing the directions of rotation, the windings of every two rows of located parts of the stator have the opposite phase rotation and the opposite direction of the helix, and the po-itor winding is made from parts alternating around the circumference, in some of which the rods are located parallel to the axis of rotation of the rotor, in others - perpendicular to it.
