The invention relates to electromechanics, mainly to the field of two-speed drive, and can be used in washing machines of the drum type, of a lifting-vehicles for the implementation of high or low speed, in robotics, which will eliminate the special drive rotation platform of the robot.

Known two-speed gearboxes described, for example, in the book "the End induction motors integrated manufacturing" - M.: Energoatomizdat, 1988 - 304 C., Il. ISBN 5-283-00496-1, author Ignatov, VA, motor AG company OYAKO, consisting of low-and high-end asynchronous Sanatornaya engine and gearbox. The rotor of each motor is mounted on the shaft for movement and is spring-loaded. Motors are used to drive machinery, hoisting and conveying devices. The disadvantage of this gear motor is that you must use a two-speed (low-speed and high-speed) motors.

The closest in technical essence is the orbital motor-reducer, RF patent 2217586/A.M. Litvinenko. - Orbital motor-reducer / publ. 27.11.2003, NC 41/06, C-ka 2001106414/09 from 06.03.2001. Orbital motor-reducer contains outer and inner stators with windings, a block of two orbital the different rotors, installed in the driver and having a squirrel-cage winding, a braking device, which includes the winding of the brake, which interacts with a spring-loaded brake rod from the brake plate and mounted in the bearing, the flange and the housing. Block rotor provided with a magnetic circuit with an additional winding is placed in midurethral space.

The disadvantage of analog is complicated manufacturing technology end of the stator.

The invention aims to simplify the manufacturing end of the stator. This is achieved by the fact that the orbital motor-reducer, mainly end of the type with inner and outer stators with windings, a unit of orbital rotors installed in the driver, the brake device, the flanges and housing, according to the invention the inner and outer stators made in the form of cylindrical cores with windings provided with an additional G-shaped magnetic circuits that are installed in the area of teeth, the cylindrical cores. Figure 1 shows a view of the stator from the rotor, figure 2 - section vertical to the axial plane.

The geared motor has a housing 1, disk end anchors (rotors) - 2 satellites, equipped with the output shaft 3 mounted in the bearings 4, carrier 5. On the drive rod 5 bearings 6 mounted rotors-2 satellites. Meets the brake, includes brake element - the core 7 with the brake pad 8, which interacts with the coil 9 and a spring 10. Plate 8 communicates with the disk 11, which is mounted in the bearing 12, the inner part of the disk 11 is a ring gear of the internal gear which cooperates with the teeth 13 of the rotor-satellite 2. The rotor is the satellite has a magnetic core with squirrel-cage winding 14, which is active in the area of external and internal face of the stator. End stators are collected in the form of a cylindrical cores with windings - external 15 with the coil 16 and the inner 17 and a winding 18. On the inner side of the outer magnetic core and the outer side of the inner magnetic core of the stator is installed 19 external and internal 20g-shaped yokes with horizontal sections adjacent to the teeth of cylindrical cores with windings, and the vertical form, the teeth of the end of the stators. Fastening is made, for example, using an external 21 and 22 internal spacer rings, which have a conical surface. With spacer rings contact pressure ring 23, the holes which are placed in tension bolt 24 and nut 25 and a nut 26. Between the magnetic circuits are external 27 and 28 internal dielectric insert, which perform the role of the slots.

<> The device operates as follows : at low speed, the coil 9, the spring 10 is compressed, the core 7 with the cover plate 8 inhibits the disk 11. Thus, the ring gear is fixed relative to the housing. The stators 15 and 17 are enabled and the rotors 14 arise torques. Rotors-2 satellites, obkatyvalisj on three-toothed wheel, do the orbital motion, resulting in the rotation of the carrier 5 to the output shaft 3.

At high speed brake is on, the coil 9 is deenergized. The spring 10 presses the brake element 7 and 8, is released the disc with the ring gear, which rotates freely in the bearing 12. The rotors 14 are now an integral rotor, which rotates according to the intended field end stators formed cylindrical magnetic circuits 15, 17 and G-shaped manipravalam 19, 20, respectively. Both locked rotor 14 form the composite rotor. He rotates the ring gear in the bearing 12, thus, the gear ratio from a compound of the rotor to the shaft 3 is equal to the unit, the shaft rotates with podsyhanii speed.

When switching again to a lower speed switching occurs in reverse order.

The outer end of the stator can be made on the basis of the usual cylindrical stator with an internal rotor. Under these conditions, the outer l-shaped magni is aproved 19 is a continuation of teeth, and insulation inserts or the distance between the magnetic circuit is analogous to the slots.

The inner active zone of the engine of the motor-reducer may be formed using a cylindrical stator used with external rotor, and may be used stationary phase rotor asynchronous motor or armature of a DC motor with sections, sealed on three-phase circuit. In this case, an l-shaped laminated magnetic core 20 is fixed on the outside and acts as a continuation of the internal teeth of the stator, and the insulation between the role of the slots.

The presence of chitosanase allows G-shaped manipravalam 19, 20 can take the form of a cylindrical surface of the inner and outer stators, which contributes the most complete conformance to manipravalam to the teeth, reducing transient magnetic resistance, and also simplifies the manufacturing technology through the possible exception of the operation of grinding in the pot.

The advantage is that by using a simple and reliable G-shaped magnetic circuits with a cylindrical stator, it is possible to improve the manufacturability of the device.

Orbital motor-reducer containing inner and outer stators, the unit of orbital rotors installed in the driver, brake devices, flanges and housing, the tives such as those his inner and outer stators made in the form of cylindrical cores are additionally equipped with G-shaped magnetic circuits installed in the area of teeth inside the outer and outside the inner cylindrical cores.

FIELD: electricity.

SUBSTANCE: present invention relates to electrical engineering and electromechanics, particularly to electric machines, and pertains to distinct features of design of a planetary electric motor - reducing gear with a lever for controlling the commutator. To increase excentricity of rotation of the commutator by several times compared to excentricity of the satellite - armature, the proposed planetary electric motor - reducing gear employs a lever for controlling the commutator. The proposed planetary electric motor - reducing gear has a planetary gear system in form of a friction pair or planetary reduction gear, the first step of which executes functions of the stator and satellite - armature of the electric motor. The commutator rotates synchronously with the satellite - armature. The stator and satellite - armature are fitted with solenoid coils, which shift the satellite - armature about the point of maximum entrance of teeth of the wheel and primary pinion of the planetary reduction gear into each other, or about the point of contact of the friction pair. The commutator, which can rotate excentrically about the housing, provides for phase shifting of the electromotive force of the electric motor and closes the solenoid coils of the stator and satellite - armature. The lever for controlling the commutator has different arms, the end of the shorter one of which engages the statellite - armature, and the end of the longer one enters the collector, providing for its rotation with excentricity, which exceeds excentricity of rotation of the satellite - armature. The commutator can be used with butt-end and cylindrical arrangement of contacts. The current input and output elements of the commutator do not rotate, they only oscillate.

EFFECT: improved operation of a planetary electric motor - armature, reduced spark formation of the brushes and electric arc from commutator contacts, as well as provision for wide regulation of frequency of rotation, torque and reversing the electric motor.
