Technical field
This utility model relates to permasyn morot, the concentratred winding permanent magnet motor that a kind of compressor using bearing-free direct connection is special.
Background technology
At present the compressor major part in Chinese market uses conventional asynchronous motor, with the coupling method of compressor host head also based on belt transmission and shaft coupling transmission.Its shortcoming is obvious: volume is big, and efficiency is low, and energy consumption is big, and fault rate is high, need to often safeguard.Although occurring in that frequency conversion permanent magnet compressor on nearly 2 years markets, permagnetic synchronous motor is used to drive, although its efficiency is with the obvious advantage with conventional asynchronous motor, but the structure of magneto is identical with normal asynchronous (has front and back bearings, front and rear cover, independent blower fan etc.), motor bearings needs periodic maintenance, and fault rate is high (fault of motor more than 60% is that bearing causes).
Utility model content
For the problems referred to above, this utility model provides the concentratred winding permasyn morot of a kind of compressor special bearing-free direct connection, to solve the problems of the prior art.
To achieve these goals, the technical solution of the utility model is as follows:
The concentratred winding permasyn morot of compressor special bearing-free direct connection, it is characterised in that include support, rotor, stator coil, fan blade, wind scooper, protective cover, lifting bolt；Wherein, the flange of support directly couples with the flange of compressor host, the bearing-free main shaft of rotor directly couples with the projecting shaft of compressor host, and described rotor is p-m rotor, stator coil is centralized winding type stator coil, the enamel-covered wire of described centralized winding type stator coil is wound on skeleton, is fixed on the stator tooth of stator core by slot wedge；Fan blade is directly anchored on rotor, and wind scooper, protective cover, lifting bolt are separately fixed on support.
In a preferred embodiment of the present utility model, the rotor punching of described rotor includes punching body, the middle part of described punching body includes that axle connecting hole, the cylindrical of punching body are arranged at intervals with gap slot, and punching body is further opened with the tri-angle-holed of circumference uniform distribution.Further, described punching body is further opened with strip gap.
In a preferred embodiment of the present utility model, the degree of protection of described electric machine casing uses IP23.
This utility model has obvious technical characterstic compared with existing compressor motor special, specifically have: 1. motor stator uses the centralized winding of particular design, coordinate special rotor design scheme, on the premise of ensureing the most excellent performance, make structure simpler, production technology is simpler efficiently, it is simple to improve production efficiency；2. using the direct connection technology humanized of bearing-free, simple in construction, failure rate is low, transmission efficiency is high, reliable；3. motor uses natural air cooled cooling scheme, rotor carries fan blade, by special wind path design, is not required to extra independent cooling fan, simple in construction, reduces the power consumption of complete machine simultaneously, indirectly improve the operational efficiency of compressor complete machine；4. degree of protection uses IP23, has filled up the blank of prior art, is the special permanent-magnet synchronous oil-cooled motor of the compressor of a kind of novel unique bearing-free direct connection.
Feature of the present utility model see graphic and the most preferably embodiment the detailed description of this case and obtains and be well understood to.
