Technical field
The utility model relates to motor, is specially a kind of planetary structure motor.
Background technology
Existing motor comprises stator and rotor.Winding all is set on stator and the rotor, realizes the exchange of energy between the stator and rotor by electromagnetic induction.Existing motor is owing to structural reason, and its output speed is higher, realizes relatively difficulty of the slow-speed of revolution, big torque output, and therefore, motor often need drive load by decelerator.
Summary of the invention
The utility model provides a kind of motor with brand new---planetary structure motor in order to solve the problem of difficulty of the existing conventional motors output slow-speed of revolution, big torque ratio.
The utility model is to adopt following technical scheme to realize: the planetary structure motor, comprise the stator and the rotor that are provided with three phase windings in it, rotor comprises the rotor matrix of being made and had on it at least two secondary rotor chamber by permeability magnetic material, be provided with secondary rotor in the secondary rotor chamber on the rotor matrix, secondary rotor is made by permeability magnetic material and is had teeth groove on its surface, secondary rotor by secondary armature spindle and through bearings on rotor matrix, an end of secondary armature spindle stretches out rotor matrix and is fixed with planetary gear at the axle head of secondary armature spindle; Also comprise through the power output semiaxis of bearings on stator, an end of power output semiaxis is provided with the internal gear that is meshed with the planetary gear of secondary armature spindle axle head.Because rotor matrix and the secondary rotor on it make whole rotor form the salient pole type structure, when three-phase stator winding passes to three-phase alternating current, produce rotating magnetic field, because of secondary rotor magnetizes than angle of rotating magnetic field hysteresis, this has just produced torque, and secondary rotor is justified the formation planet rotation of rolling in stator.Because the planetary gear of secondary armature spindle axle head and internal gear engagement drive the rotation of power output semiaxis.The transmission of the internal gear of planetary gear by secondary armature spindle axle head and power output semiaxis one end, the high speed rotating of rotor can be become the low speed of power output semiaxis, big torque rotation, change internal gear and the planetary tooth of joining, gearratio can be chosen in the i=20-300 scope, thereby makes this motor easily realize the output of low speed, big torque.
One end of this motor rotor matrix covers in stator terminal through bearings, and the other end is exported on the semiaxis in power through bearings.Like this, the engagement of rotor one end between planetary gear and internal gear supported, also have axle to support, make the rotation support of rotor more reliable, more reasonable structure is moved more stable, reliable.
The bearings right panel that the rotor matrix of this motor rotor has an axle head by afterbody semiaxis, magnetic conductor, bearings left side plate and a side successively is connected and fixed and forms; Described secondary rotor chamber is opened on magnetic conductor, and the bearing that supports secondary armature spindle is individually fixed between afterbody semiaxis and magnetic conductor, bearings left side plate and the right panel.Above-mentioned rotor matrix is rational in infrastructure, is convenient to processing and assembling, also is convenient to the assembling and the installation of secondary rotor simultaneously.
Planetary structure electric tools described in the utility model has following characteristics: 1, there is not winding on the rotor, and simple in structure, cost is low.2, use simply.This motor directly adopts the three-phase alternating current power supply.Can start voluntarily, need not control device.3, have good starting, braking and speed adjusting performance.The starting current of this motor is lower than threephase asynchronous, in high-power starting easily down.Its braking ability is consistent with starting performance.As long as reduce the frequency of three-phase alternating current and change the intensity of controlling voltage,, has very wide adjusting range simultaneously during speed governing with regard to the may command rotating speed of motor.But 4 Fraquent starts and braking.This motor is less owing to starting current, so but Fraquent start and braking, electric machine temperature rise is low.5, connect simply with load.This motor can easily directly be exported low speed high torque, can directly connect with load, takes down decelerator, reduces cost, and improves reliability.6, the equal exportable multiple rotating speed of magnetic field number of poles.7, the scope of application is extensive.Anyly all can directly use, particularly the drive system of the high-power drag conveyor of large band conveyer and coal-face under the coal mine by electric motor driven low-speed device.
