Double-rotor electric motor with controlled shaft rotations
SUBSTANCE: invention relates to the field of electrical engineering and transport machine building and may be used in development of mechanisms, in which it is necessary to change torque and rotations of an output shaft of an electric motor. According to this invention, in an electric motor a differential gear is used as a converter of transmission ratio, and the gear comprises one input and two outputs, the input of which is connected to a rotor of the electric motor, one of outputs, to which a high torque is sent, is connected with an output shaft, and the second output is connected with the second rotor, which is inductively connected with the rotor of the electric motor, and in case of their mutual rotation, it generates electric energy, and force arising at the same time, by changing which, through variation of inductive connection between rotors, the speed up rate may be controlled, as well as output shaft rotation speed, partially blocking the gear, aims to reduce mutual relative opposite rotation of the electric motor rotor and the second rotor. The second rotor is also connected with a speed-up coupling, which is connected with the body by a response part, and preventing rotation of the second rotor to the side opposite to direction of the electric motor rotor rotation.
EFFECT: multiple increase of electric motor torque in case of speeding.
The invention relates to the field of transport engineering and other mechanisms that need changing speed of the output shaft with the torque change of the motor.
There are various ways to change the speed of the shaft of the AC motor. The main method of a smooth change of speed is the management of power line frequency AC using inverters. This method is described in the literature. For example: Waldek A.I. of the Electric machine. Leningrad. Energy, 1978, str-572. Motor with two rotors with the ability to control the speed of the output shaft is also described in patent No. 2345468.
The disadvantage of this method is the high cost of converters, their complexity, low efficiency, the unreliability and the fact that converters for electric motors with high power has not yet established a reliable element base. The disadvantage of the method described in patent No. 2345468 is no possibility of the repeated increase in torque on the output shaft during acceleration.
The objective of the invention is to enable a smooth change of speed of the output shaft of the device with the change of gear ratio and torque throughout the speed range, depending on load, when the optimal mode of operation of elektrodvigatel is permanent, optimal speed and, as a result, achieving optimality of the accelerating performance, increasing efficiency, reduce production, and simplified management.
This goal is achieved by the fact that, according to the invention, in the motor, as a Converter gear ratio, use differential transmission of any known type, having one input and two outputs, the input of which is connected to the rotor of the electric motor, one of the outputs, which is transmitted more torque, connected to the output shaft and the second output is connected with the second rotor, which is inductively associated with the rotor of the electric motor and at their mutual rotation generates electricity, and the power arising from this, which changes by modifying the inductive coupling between the rotors, you can control the acceleration and speed the rotation of the output shaft, partially blocking the transmission, reduces the desire for mutual relative opposite rotation of the rotor of the electric motor and the second rotor. The second output is also connected to the overrunning clutch, second part connected to the housing and preventing rotation of the second rotor in the direction opposite to the direction of rotation of the rotor of the motor, which leads to an increase in torque of the electric motor during acceleration. During rotation the rotor of motor rotation from the input of the transmission is transmitted to the output shaft and the second rotor, inductively associated with the rotor of the electric motor, which, as it rotates, moves the second rotor electromotive force, and in the presence of a controlled load in his chain, if necessary, with adjustable force partially blocks the transmission along the second rotor, causing the entire differential mechanism to rotate around its axis, in order to reduce the mutual relative rotation between the rotors. This leads to the increased speed of the output shaft and to control the growth rate of its turnover, which can change when the ratio of torque, depending on the size of the load in the circuit of the second rotor and the torque on the output shaft. This allows for constant optimum speed rotor of the motor to change, depending on the load torque and the speed of the output shaft. The second output is also connected to the overrunning clutch, which mate is connected to the housing. During acceleration, the load on the output shaft, the second rotor tends to rotate in the opposite direction. This is prevented by the overrunning clutch connected with him. The second rotor is stopped and the differential transmission works like a gear with a large gear ratio, increasing in proportion ratio torque on the output shaft. When the engine will spin the I around its axis to such speed, that the overrunning clutch will be released from the compound, further acceleration will occur when torque equal to the torque developed by the rotor of the electric motor. When you increase the load on the output shaft of the second rotor will seek to reverse rotation, the overrunning clutch will again be to prevent this and torque on the output shaft will again increase the speed of the output shaft decreases, and the speed of the rotor of the motor will remain unchanged.
The invention is illustrated in the drawing. In the drawing, for example a motor with a vertical axis of rotation. The stator 1 is inductively connected to the rotor 2, which is mounted on a drive rod 3 differential transmission and installed a pair of satellites 4 and 5, which obkatyvalisj two Central wheels of different diameters 7 and 8. The Central wheel 7 is connected with the output shaft 6, and the Central wheel 8 rotates freely on the shaft, but connected with the overrunning clutch 9 and the second rotor 10. When the rotor of the electric motor 2 satellites tend to rotate the Central wheel in different directions. But the overrunning clutch 9 prevents the rotation of the second rotor in the reverse rotation direction and the Central wheel 8 is stopped, and the rotation is transmitted via satellites to the Central wheel 7 and the output shaft 6. The rotor of the electric motor 2 inductively the points the user to the second rotor 10, therefore, the second rotor when the rotor of the electric motor generates the electric power and the force arising from the presence of a load in his chain, carries the second rotor in the same direction, which rotates the rotor of the motor, partially blocking differential, causing the entire mechanism to spin around its axis, reducing the total gear ratio of the mechanism consisting of a gear ratio of the gear transmission and rotation mechanism around its axis. Its final drive ratio is changed from the maximum value defined by the gears of the transmission, when the rotation is transmitted only through the transmission gear, to one, when the whole mechanism rotates on its axis, the satellites along the Central wheels don't roll, but the rotors no mutual relative rotation, which is possible, as in the case of magneto electric coupling, only when there is no load on the output shaft. With the increase of the electric load in the circuit of the second rotor increases the magnitude of the force, taking him by the rotor of the electric motor, the acceleration rate of the output shaft increases.
Double-rotor motor with controllable speed of the shaft, wherein according to the invention, in the motor, as a Converter gear ratio, use differential transmission of any of the local type, having one input and two outputs that transmit different torques, the entrance of which is connected to the rotor of the motor, one of the outputs, which is transmitted more torque, connected to the output shaft and the second output is connected with the second rotor, which is inductively associated with the rotor of the electric motor, and when their mutual relative rotation produces electricity, and the power arising from this, which changes by modifying the inductive coupling between the rotors, you can control the acceleration and speed of rotation of the output shaft, partially blocking differential gear, aims to reduce the mutual relative opposite rotation of the rotor of the electric motor and the second rotor, which is also connected to the overrunning clutch, second part connected to the housing and preventing rotation of the second rotor in the direction opposite to the direction of rotation of the rotor of the motor, which leads to an increase in torque of the electric motor during acceleration.

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.
