Description
Technical field
The utility model belongs to motor and makes the field, relates to a kind of adjustable-speed motor, especially a kind of high pressure 2 utmost point inner feedback speed-regulating motors.
Background technology
Present big-and-middle-sized high pressure 2 pole motors are all the cage rotor motor, and also have only 4 extremely above motor (comprising 4 utmost points) in the inner feedback speed-regulating motor.Existing high pressure 2 utmost point cage rotor motor speed adjustings need be by changing the high voltage source frequency, frequency converter cost height, and efficient and power factor are low.
The utility model content
The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art, a kind of high pressure 2 utmost point inner feedback speed-regulating motors are provided, this motor application of this kind adjustable-speed motor copped wave inner feedback speed-regulating control system, the rotor and the internal feedback winding of control low voltage side, control is reliable, efficiency is high.
The purpose of this utility model solves by the following technical programs:
This kind high pressure 2 utmost point inner feedback speed-regulating motors, comprise support, be installed on the rotating shaft on the support, be located at the rotor coil in the rotating shaft and be located at stator coil on the support, the upper end of described support is provided with Backpack type sky-water cooler, the rotor cable of being drawn by described rotor coil is connected with collector ring, and described collector ring is connected with spring coupling with this motor body; Be connected with a cover internal feedback coil on the described stator coil and form the stator winding of this motor; The centrifugal blower that increases by two forced ventilations at the two ends of described sky-water cooler forms the wind path of motor interior.
The colligation of netted no latitude band, banding are adopted in above-mentioned rotor coil end.
Above-mentioned motor adopts the low-loss silicon steel sheet, the silicon steel sheet japanning.
Rotor of the present utility model is the structure of wound rotor band collector ring, in stator winding, increased by a cover internal feedback coil, make high pressure 2 pole motors reach the purpose of inner feedback speed-regulating, and it is big that the utility model has overcome 2 utmost point cage rotor motor starting electric currents, the shortcoming that starting torque is little; The application of this motor has reduced harmonic content simultaneously, has improved effect, has saved electric energy.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Wherein: 1 is support; 2 are rotating shaft; 3 is rotor coil; 4 are the internal feedback coil; 5 is stator coil; 6 is sky-water cooler; 7 is shaft coupling; 8 is the end cover type sliding bearing; 9 is centrifugal blower.
Embodiment
Below in conjunction with accompanying drawing the utility model is done and to be described in further detail:
The utility model is to improve in existing motor base (MB), its structure as shown in Figure 1, this figure is the structural representation after motor loam cake (on be covered with sky-water cooler 6) is opened, as known in the figure: high pressure 2 utmost point inner feedback speed-regulating motors of the present utility model, comprise support 1, be installed on the rotating shaft 2 on the support 1, be located at the rotor coil 3 in the rotating shaft 2 and be located at stator coil 5 on the support 1, the upper end of support 1 is provided with Backpack type sky-water cooler 6.The rotor cable of being drawn by rotor coil 3 is connected with collector ring 10, and this collector ring 10 is connected with spring coupling 7 with motor body.Be connected with a cover internal feedback coil 4 on the stator coil 5 and form the stator winding of this motor.The centrifugal blower 9 that increases by two forced ventilations at the two ends of sky-water cooler 6 forms the wind path of motor interior.In the utility model, the colligation of netted no latitude band, banding are adopted in rotor coil 3 ends.And motor of the present utility model adopts the low-loss silicon steel sheet, the silicon steel sheet japanning.
In sum, because the synchronous speed of high pressure 2 utmost point inner feedback speed-regulating motors of the present utility model has reached 3000 rev/mins, so rotor linear velocity height, centrifugal force are big, so the electric motor structure design is most important, in addition, this motor speed is adjustable, so the rotating shaft design is necessary for stiff shaft, and compact conformation, the motor shaft spacing is short, can effectively reduce the vibration of motor.In addition, aspect Electromagnetic Design, the power factor when improving this motor low speed takes into full account the magnetic circuit distribution situation of motor during this design of electrical motor, and the yoke portion magnetic that reduces rotor is close; This motor has reduced the eddy current loss of rotor, has improved efficiency of motor.
