Abstract
The utility model discloses a novel high-power three-phase asynchronous motor for frequency conversion and speed regulation. The motor comprises a motor base and a motor shaft. An end cover is respectively arranged on the front and the rear ends of the motor base. Through holes are arranged on the end covers. The two ends of the motor shaft are arranged in the through holes through a bearing, an inner bearing cover and an outer bearing cover, and extend out of the motor base. A cooling fan is arranged at the rear end of the motor shaft, and the cooling fan is arranged on the rear side of the motor base. A stator and a rotor sheathed on the motor shaft are arranged in the motor base. A junction box is arranged on the motor base. The utility model is simple in structure. The motor is driven by a 400V three-phase voltage power of low voltage, and runs steadily during the operation from low frequency to high frequency without torque ripple phenomena. The utility model also has the advantages of low noise, high starting torque and small starting current.
Description
Technical field:
The utility model relates generally to the threephase asynchronous machine field, relates in particular to novel high-power frequency control threephase asynchronous.
Background technology:
For a long time, in China machinery industry especially in the application of products such as powerful blower fan and water pump, the high-tension motor that drive motors adopted is its manufacturing cost height not only, and working service and auxiliary facility require also high, particularly use the occasion of variable-frequency speed-adjusting energy-saving at needs, owing to be subjected to the restriction of aspects such as high voltage converter price and security reliability, make the large tracts of land of high-pressure frequency-conversion power-saving technology promote comparatively difficulty.In the cost contrast of governing system, the advantage of low-voltage variable frequency governing system is then fairly obvious, and motor adopts frequency control to drive products such as blower fan and water pump, can be energy-conservation in a large number, more the person at insulating material that high-voltage motor adopts of equal-wattage etc. quantitatively considerably beyond the low-pressure high-power frequency control motor.Therefore press for the speed governing of development of new high-power frequency conversion on the market and satisfy instructions for use with threephase asynchronous.
The utility model content:
The utility model purpose is exactly in order to remedy the defective of prior art, a kind of novel high-power frequency control threephase asynchronous to be provided, and it is simple in structure, has efficient, energy-conservation, noise reduction, advantage that reliability is high.
The utility model is achieved through the following technical solutions:
Novel high-power frequency control threephase asynchronous, include support, motor shaft, the front and back ends of described support is separately installed with end cap, have through hole on the end cap, described motor shaft two ends are installed in the described through hole by bearing, internal bearing cover and bearing end cover and stretch out the support outside, it is characterized in that: described motor shaft rear end is equipped with cooling blower, and cooling blower is positioned at the support rear side; Be provided with stator in the described support and be sleeved on rotor on the motor shaft, terminal box is installed on the support.
The utility model is except the power grade that national Specification is arranged, also can design separately motor electromagnetic part (stator and rotor cores size, flute profile size, coil parameter etc.) according to the load size, when guaranteeing the motor Essential Performance Requirements, power of motor and load are complementary, have avoided motor " low load with strong power " in service phenomenon.
The utility model has the advantages that:
The utility model is simple in structure, adopts low pressure 400V three-phase voltage power drives, and motor in not only running in service from the low frequency to the high frequency steadily but also do not have torque ripple phenomenon and has lower noise and higher starting torque and less starting current.
Description of drawings:
Accompanying drawing is a structural representation of the present utility model.
Embodiment:
Novel high-power frequency control threephase asynchronous, include support 1, motor shaft 2, the front and back ends of described support 1 is separately installed with end cap 3, have through hole on the end cap 3, described motor shaft 2 two ends are installed in the described through hole by bearing 4, internal bearing cover 5 and bearing end cover 6 and stretch out support 1 outside, described motor shaft 2 rear ends are equipped with cooling blower 7, and cooling blower 7 is positioned at the support rear side; Be provided with stator 8 in the described support 1 and be sleeved on rotor 9 on the motor shaft 2, terminal box 10 is installed on the support 1.
