Permanent-magnet motor

FIELD: electrical engineering; drive motors.

SUBSTANCE: proposed permanent-magnet motor has twin stator incorporating permanent magnets in the form of U-section solenoids disposed on inner surface of stator and two rotors, one per each permanent-magnet section, in the form of arched bars rigidly coupled with axis of revolution, as well as coupling and flywheel. Rotor magnet is attracted by stator solenoid due to interaction of unlike-polarity poles of stator and rotor magnets which turns rotor through definite angle until like-polarity poles of stator and rotor magnets are aligned. As rotor magnet end front along its running leaves dead zone, it is pushed out of stator magnet and ensures continuous rotary motion. When rotor passes through dead zone, its rotary motion is maintained by flywheel and dc machine running as motor supplied with power from storage battery that functions to help rotor pass through dead zone. Upon leaving dead zone rotor shaft load reduces and dc machine runs as generator. In his way electrical energy is recuperated and used for booster charge of storage battery.

The present invention relates to mechanical engineering and can be used in other sectors of the drive.

It is known device [1] is the drive containing the stator with permanent magnets, a rotor with permanent magnets, the shaft, bearings and screens.

A disadvantage of the known device is the presence of an inhibitory interaction between the magnetic fields of permanent magnets of the stator and rotor, adjust the drive power by changing the distance between the magnets of the stator and rotor, and the brake actuator is carried out by turning the magnets of the stator, that is not workable and not perfect, reduces the efficiency and capacity of the drive.

The aim of the present invention is to increase the capacity and efficiency of the engine, simplifying management in the process of operation.

This goal is achieved by the fact that the engine contains two dual stator with permanent magnets, made in the form of solenoids U-shaped section located on the inner surface of the stator and two rotors with permanent magnets, made in the form of arcuate rods rigidly connected with the common axis, and an auxiliary regulating the DC motor.

It is known that the permanent magnets of opposite poles attract and similar poles ottalkivayut is. Permanent magnetic solenoids of arcuate stator and the magnets of the rotor at a meeting unlike poles attract one another, so that the magnets of the rotor is pulled into the solenoid magnets of the stator and the rotor is rotated together with the axis at some angle.

Until the magnets of the stator and the rotor at head similar poles formed "dead zone" and the load on the shaft will increase and further rotation of the rotor will occur due to the energy of a rotating flywheel located on the same axis as the rotor, and energy anchor auxiliary self-regulating DC motor until the magnet rotor front end in the course will go beyond the "dead zone", which will push the magnet of the rotor cavity solenoidal magnet stator and the rotor rotation will increase, and the load on the shaft will fall.

With the passage of the magnet rotor "dead zone" other magnets positioned in the rotor, or involved in the respective magnetic coils of the stator, or are pushed out of them depending on their location in the solenoids, which helps to maintain the continuity of the rotation. Then the cycle repeats, which ensures the uninterrupted operation of the engine. As for samoreguliruemaja DC motor, it will switch to generators, the Torah, will recovery of electric energy, which will charge the battery. The magnets of the rotor are displaced relative to each other at a certain angle. Changing the offset angle allows you to adjust the mode of operation of the engine and its power.

Figure 2 is a side view in section.

The permanent-magnet motor includes two stator 1 with constant solenoidal magnets 2, 3, 4, 5, 6, 7, 8, 9 (the magnets 8 and 9 are not shown), arranged in two sections, a rotor with permanent arcuate magnets 10, 11, 12, 13, 14, 15 (the magnets 13, 14, 15 marked on the second rotor by the dotted line), the flywheel 18, the clutch 19, the axis 16, the bearings 17, the handle 20, self-regulated DC motor 21, a battery 22.

The engine works as follows: when the interaction between the unlike poles of the permanent magnets of the rotor and stator of the solenoid magnets of the stator 2 initially involve arcuate magnets of the rotor 12 (Fig 1) and the rotor is rotated at a certain angle until the stator magnets with similar poles will at head with magnets of the rotor and the rotor will be included in the "dead zone", the load on the motor shaft will increase and self-regulating a DC motor powered by a battery, together with the flywheel will help the rotation up to the moment when the magnet rotor is arenim during the end will go beyond the "dead zone", the result will be popping magnet rotor magnet stator (1 magnets 4 and 10) and the rotation of the rotor will increase, which will ensure smooth rotation of the rotor, and self-regulating DC motor switches to generator with recuperation of electric energy for recharging the battery. Then the cycle is repeated and there is a continuous rotation axis 16. Stop, start and reverse the engine is carried out using a DC motor.
