Description
Technical field
The utility model relates to a kind of permanent magnet direct current motor, but the permanent magnet direct current motor of particularly a kind of synchronous operation and control.
Background technology
Permanent magnet direct current motor is to utilize permanent magnet to set up the DC motor of excitation field, the excitation system of this motor because of not establishing in addition, thereby volume is little, in light weight, simple in structure, and efficient is high.
Existing permanent magnet direct current motor can not synchronous operation; And in some application scenario (like caravan); Then need both have these advantages of permanent magnet direct current motor, how motor that again can synchronous operation is so to provide a kind of motor that satisfies these requirements just to become the problem of confronting.
The utility model content
But the purpose of the utility model provides the permanent magnet direct current motor of a kind of synchronous operation and control, to satisfy under some application scenario, and to both having the advantage of permanent magnet direct current motor, the demand of motor that again can synchronous operation.
The purpose of the utility model realizes through following technical scheme:
But the permanent magnet direct current motor of a kind of synchronous operation and control; Comprise support, stator, rotor, brushgear housing, front end housing and rear end cap; Said brushgear housing is installed between said support and the rear end cap; Also comprise Hall speed probe and magnetic field of permanent magnet conductor; Said magnetic field of permanent magnet conductor is installed in said rotor shaft on the part between brushgear housing and the rear end cap, and said Hall speed probe is arranged on the position that can respond to said magnetic field of permanent magnet conductor between said brushgear housing and the rear end cap.
Further; But the synchronous operation of the utility model and the permanent magnet direct current motor of control also comprise and suppress the electromagnetic disturbance filter circuit, and said inhibition electromagnetic disturbance filter circuit comprises capacitor C 1, C2 and inductance L 1, L2, and said inductance L 1, each connects with a brush L2 respectively; Said capacitor C 1 one ends are connected the end of inductance L 1 away from brush; Other end ground connection, said capacitor C 2 one ends are connected the end of inductance L 2 away from brush, other end ground connection.
Particularly, said capacitor C 1, C2 and inductance L 1, L2 and Hall speed probe all are arranged on the metallic stamping pieces, and said metallic stamping pieces is installed in the space of reserving between said brushgear housing and the rear end cap.
The beneficial effect of the utility model is: come the rotating speed of motor is responded to through installing magnetic field of permanent magnet conductor and Hall speed probe in existing permanent magnet direct current motor, and induced signal is transferred to controller, then; By controller the signal that is received is handled, and regulated the motor input voltage within the specific limits automatically, rotating speed of motor is changed; Thereby reach needed synchronous speed, realize synchronous operation and control, simultaneously existing permanent magnet direct current motor; Installing suppresses the electromagnetic disturbance filter circuit in motor; Suppressed the generation of spark between brush and commutator segment, avoided the interference of electromagnetic disturbance, made induced signal truer the Hall speed probe; Controller is more accurate to the control of motor synchronous operation in view of the above, and the operation of motor is just more synchronous.
Description of drawings
According to accompanying drawing and embodiment the utility model is done further explain below.
But Fig. 1 is the structural representation of permanent magnet direct current motor of synchronous operation and the control of the utility model.
Fig. 2 is the connection layout that is used for the inhibition electromagnetic disturbance filter circuit of the utility model.
Among the figure: 1, support; 2, rotor; 3, brushgear housing; 4, rear end cap; 5, Hall speed probe; 6, magnetic field of permanent magnet conductor; 7, metallic stamping pieces.
Embodiment
Shown in Fig. 1～2; But the synchronous operation of the utility model and the permanent magnet direct current motor of control; Comprise support 1, stator, rotor 2, brushgear housing 3, front end housing and rear end cap 4; Said brushgear housing 3 is installed between said support 1 and the rear end cap 4; Also comprise Hall speed probe 5 and magnetic field of permanent magnet conductor 6, said magnetic field of permanent magnet conductor 6 is installed in said rotor shaft on the part between brushgear housing 3 and the rear end cap 4, and said Hall speed probe 5 is arranged between said brushgear housing 3 and the rear end cap 4 can be responded on the position of said magnetic field of permanent magnet conductor 6.
