A kind of planet motor

Technical field

The utility model belongs to machine field, relates in particular to the electric rotating machine that a kind of rotor is done planetary motion.

Background technology

Present all types of electric rotating machine, rotor and stator concentric, rotor is only around rotating from axle.For synchronous motor, allow rotor, need to be aided with complicated electron controls technology, take direct current machine as example, brushless or brush motor is when rotating, and the energising direction of motor coil needs checker, and motor is rotated continuously, the commutation of brush motor is finished jointly by commutator and brush, and brushless electric machine is finished by transducer and controller.The utility model mechanical mechanism does not just exist in order to commutate, its not only controlling magnetic field upset, and can carry out mechanical speed governors.

Summary of the invention

The brush motor carbon brush will produce pollution, electric spark, the most dependence on import of the control chip of brushless electric machine, and also high to environmental requirement.For the commutation problem that brush motor and brushless electric machine relate to, the mode that the utility model is done planetary motion with rotor solves, the upset of rotor rotation band moving field, and current direction is selected in revolution.

Rotor of the present utility model is done planetary motion, and namely on one side around self central axis rotation, on one side around the revolution of stator center axis, the planetary motion mode of rotor is realized by planetary gears.Planetary gears mainly is comprised of planetary gear, centre wheel and planet carrier.Centre wheel is divided into again sun gear and ring gear, and the external tooth centre wheel is defined as sun gear, and central wheel of internal teeth is defined as ring gear.Z1 represents the sun gear number of teeth, and Z2 represents the planetary gear number of teeth, and Z3 represents the ring gear number of teeth, and each gear number of teeth satisfies the geometrical relationship of planetary gears: Z3=2 * Z2+Z1.

The planet motor mainly is comprised of sun gear, planetary gear, ring gear, rotor, winding, external stator, internal stator, planet carrier, casing, brake.

Rotor be fixed on the planetary gear and with planetary gear concentric, stator and centre wheel concentric.Sun gear, planetary gear, ring gear rotating speed difference can be chosen as required and carry out mechanical speed governors.

In the utility model, rotor is fixed on and does planetary motion on the planetary gear, and rotor quantity can be one or more, and the corresponding planetary gear of each rotor, rotor and planetary gear all are hinged on the planet carrier by bearing pin and can rotate the rotation of son self central axis.Divided stator internal stator and external stator in the utility model, the two uses together or only uses one of them.

The planet carrier or the centre wheel that drive in the utility model with prime mover rotate, and the utility model becomes generator, converts mechanical energy to electric energy.The utility model will realize that electric energy converts mechanical energy to, when motor uses, possess following condition.

1) ring gear is fixed

Ring gear tooth number Z 3 is integral multiples of planetary gear number of teeth Z2.

2) sun gear is fixed, Z1 〉=Z2

Sun gear number of teeth Z1 is the integral multiple of planetary gear number of teeth Z2.

3) sun gear is fixed, Z1 ﹤ Z2

Planetary gear number of teeth Z2 is the integral multiple of sun gear number of teeth Z1.

4) stator poles logarithm=rotor pole logarithm * planetary gear revolution rotation number of times

Then be DC generator when possessing the reverse use of the utility model of above-mentioned condition.

The utility model is pollution-free, without electric spark, do not have the commutation control chip of high price yet.

Embodiment

Following execution mode has been described several cases so that the reader fully understands intension of the present utility model, but the utility model has infinite embodiment, so the utility model is not subjected to the restriction of following disclosed specific embodiments.

(Embodiment 1)

Fig. 1 to Fig. 3 is a kind of embodiment of planet machine field built-in motor, and it mainly is comprised of sun gear 1, planetary gear 2, ring gear 3, rotor 4, winding 5, external stator 6, planet carrier 11, casing 9, brake 7, brake 8, bearing pin 10.Rotor 4 and planetary gear 2 are hinged on the planet carrier 11 by bearing pin 10 as a whole, and external stator 6 is fixed on the casing 9.

Press the Planetary Gear Transmission principle, through optimal design sun gear 1 tooth number Z 1=40, planetary gear 2 tooth number Z 2=20, ring gear 3 tooth number Z 3=80.Winding 5 logical direct currents, external stator 6 is 4 pairs of utmost points, rotor 4 is 2 pairs of utmost point permanent magnets.Every 45 degree, winding 5 moves towards to change once; Rotor 4 is every from turning 90 degrees, and overturns once in magnetic field.

When pressing brake 7, ring gear 3 is fixing.The permanent magnet N utmost point is facing in the winding 5 current direction paper of external stator 6, see schematic diagram 3, under the effect of electromagnetic torque, rotor 4 rotates and drives planetary gear 2 rotations, ring gear 3 gear teeth must be given reaction force of planetary gear 2 gear teeth so that planetary gear 2 rotates around sun gear 1, magnetic field is with rotor 4 upsets while rotating, rotor 4 is from turning 90 degrees, overturn fully in magnetic field, outside the winding 5 outflow of bus current paper of the extremely corresponding external stator 6 of permanent magnet S this moment, the electromagnetic torque direction remains unchanged, the sense of rotation of rotor 4 remains unchanged, the revolution direction remains unchanged, so move in circles, motor is realized rotating continuously, and output shaft is sun gear 1, planet carrier 11.

When pressing brake 8, sun gear 1 is fixing, and output shaft is ring gear 3, planet carrier 11.
