The utility model content
It is simple relatively that the purpose of this utility model provides a kind of structure, and speed adjustable range is wide, the Novel DC motor that service efficiency is high.
For reaching above purpose, the utility model provides a kind of direct current machine, comprise stator mechanism, rotor mechanism, housing, output shaft and motor base, described stator mechanism comprises annular stator and central stator, described annular stator is fixed on the inner walls, be divided into N polar ring shape stator and S polar ring shape stator, described central stator is on the central shaft of motor, comprise the central stator central excitation winding between two cylinder-shaped magnets and two magnet, two magnet positions of described central stator are corresponding with two annular stators, and the polarity of two magnet is identical with corresponding annular stator; The rotor mechanism that two annulars are arranged between described annular stator and the central stator, described two rotor mechanisms are serially connected by the rotor mechanism fixed disk, lay respectively between annular stator and the central stator, distribution rotor mechanism armature winding on the described rotor mechanism, described rotor mechanism and central stator are fixed on the electric motor end cap by stator mechanism reel and central shaft respectively, at an end of rotor mechanism fixed disk an output shaft are arranged.
Further, the rotor mechanism winding conducting wire of the inside and outside both sides of described rotor mechanism annulus is embedded in respectively in the vertical parallel slot that distributes in the inside and outside both sides of rotor mechanism.
Further, the shape of parallel slot is consistent with size, and evenly distributes in the inside and outside both sides of rotor mechanism.
Further, rotor mechanism has 2-5 rotor mechanism separation trough along the radial direction of annulus, and the rotor mechanism separation trough extends longitudinally to the other end of rotor mechanism, and rotor mechanism 14 is divided into the 3-6 equal portions, fills non-magnet material in the rotor mechanism separation trough.
The preformed hole that one group of winding conducting wire further, is arranged on the described rotor mechanism fixed disk.
Further, the quantity of preformed hole is even number, and is evenly distributed on the rotor mechanism fixed disk.
Adopt the direct current machine of above structure, because the lead of the inside and outside both sides of rotor mechanism armature winding is subjected to force direction identical all the time, the speed of rotor mechanism and the size of current by rotor mechanism armature winding lead are directly proportional like this, namely control the speed of rotor mechanism with the size of current that flows through the rotor mechanism winding conducting wire; All the time all under same polarity magnetic field, rotate because have the winding conducting wire of same current direction, need not engine commutator, saved valuable copper metal; Rotor mechanism and stator mechanism are simple in structure, and cost is low; In addition, do not produce phase place during machine operation, do not produce frequency, the vibrations of motor are little.
