Abstract
The utility model discloses a DC electric machine with improved compensation winding connecting structure, which comprises a stator and a rotor. Compensation windings are arranged in grooves on the surfaces of pole shoes of main poles of the stator. The compensation windings under the main pole of the N pole are connected in series, and the compensation windings under the main pole of the S pole are connected in series. The two series arms are connected in parallel, and then are connected in series with an armature winding. The utility model changes the compensation wind connecting structure of the DC electric machine. The existing compensation winding is connected in series with the armature winding, and the utility model alters the way of connection to parallel connection of the two arms. Thus, the current in the compensation winding is reduced to a half, and the winding can use finer conducting wires. Therefore, the number of the grooves of the compensation winding can be doubled, which makes the magnetocaloric gradient of the compensation winding decreased and reduces the fluctuation of the air gap magnetic potential. The utility model realizes the purpose of better compensating the armature reaction and improving the electric machine commutation. For simplifying the inner connection of the DC electric machine, the commutating pole winding can also be split into two mutually paralleled sets which are respectively connected in series with the compensation windings under the N pole and the S pole.
Description
Technical field
The utility model relates to direct current machine, and particularly the syndeton of direct current machine compensation winding is specially the direct current machine with improved compensation winding syndeton.
Background technology
As everyone knows, in the direct current machine more high-power, that commutation is abominable, need to adopt installing compensation winding to offset the influence of armature reaction, thereby compensate armature reaction better, reduce producing the potential difference spark, to reach the purpose of improving commutation to air-gap field.The compensation winding is embedded in the groove on main pole pole shoe surface.Compensation winding in the existing direct current machine all is in series with armature winding, electric current in the compensation winding is bigger, the sectional dimension of used lead is bigger, the lip-deep groove number of main pole pole shoe can not be too many, make that the magnetic potential gradient of compensation winding is bigger, cause the fluctuation of motor gas-gap magnetic potential still bigger, be unfavorable for improving better motor commutation.
Direct current machine with compensation winding mostly is provided with commutating pole (the commutating pole number of poles is identical with the main pole number of poles of motor), and commutating-pole winding also all is in series with armature winding.
Summary of the invention
The utility model solves existing direct current machine compensation winding and armature winding is in series, and can not improve the problem of commutation better, and a kind of direct current machine with improved compensation winding syndeton is provided.
The utility model is to adopt following technical scheme to realize: the direct current machine with improved compensation winding syndeton, comprise stator and rotor, in the groove on stator main pole pole shoe surface, be provided with the compensation winding, with the compensation winding under the N utmost point main pole be in series, compensation winding under the S utmost point main pole is in series, be in series with armature winding again after two series arms are in parallel.
The utility model has changed the syndeton of direct current machine compensation winding, the existing winding that respectively compensates all is in series with armature winding and changes two-way into and be connected in parallel, electric current in the compensation winding is reduced by half, make winding can select thinner lead for use, thereby the groove number of compensation winding is doubled, compensation winding magnetic potential steepness is reduced, and then reduced the fluctuation of magnetic potential of air gap, realized the purpose that compensates armature reaction better, improves motor commutation.
