Advantageous effect
Compared with prior art, the beneficial effects of the invention are as follows：
First, magneto technology is introduced elevator field by the present invention, and by reel as the rotor of permanent magnet motor, main shaft is made
For the stator of permanent magnet motor, designed to realize permanent magnet direct-drive built-in type Structure of hoist.
Second, built-in type is compact-sized, save space, reduce winding houses construction area or hoist pitheadfreame it is big
It is small, especially it is the reduction of the basis of elevator；It is light-weight, low cost, economic operating cost.
Third, permanent magnet synchronous motor have wider economical operation range.The economical operation range of common electric machine is generally
The 60-100% of nominal load, when being less than 60% load, the efficiency and power factor curve of motor decline quickly, operational efficiency and
Power factor is very low.And the economical operation range of permanent magnet synchronous motor is wide more than common electric machine, the not only efficiency in nominal load
It is very high, and 25-120% is specified get lodged in the range of have higher efficiency, efficiency defect is smoother, and variation is little.
4th, main shaft is disturbed curvature and is greatly reduced compared with suspension type, and spindle design does not transmit torsion at a rigid body
Square, to greatly reduce the deflection of main shaft.
5th, the deformation such as main shaft, bearing, basis is on air gap without influence.The temperature of motor, which rises, will not cause stator not right
Claim deformation, because of the uniformity without influencing air gap；Stress does not interfere with the air gap of motor in basis.
