1-motor stator, 2-traction sheave, 3-permanent magnetic iron, 4-coder, 5-plate disc brake, 6-steel rope grooving, 7-riser, 8-bearing, 9-brake disc.
Detailed description of the invention
The technological means realized for making the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with detailed description of the invention, setting forth the present invention further.
With reference to Fig. 1, this detailed description of the invention is by the following technical solutions: external rotor plane motor towing machine, comprise motor stator 1, traction sheave 2, permanent magnetic iron 3, coder 4 and plate disc brake 5, the outside face of traction sheave 2 is provided with steel rope grooving 6, the inner surface of traction sheave 2 posts permanent magnetic iron 3, as the rotor of permanent magnet synchronous motor, parts had not only used as traction sheave but also rotor as motor uses, , also use as brake disc, motor shell inside is provided with motor stator 1, motor stator 1 is wound with symmetrical three-phase alternating current coil, the midway location of motor hollow shaft is provided with coder 4, coder 4 can carry out dismounting in former and later two directions, simple and convenient, riser 7 is fixed with plate disc brake 5.
It should be noted that the side of described motor shell is provided with riser 7, be designed to cantilever structure, farthest save axial thickness space.
It should be noted that the spatially axial direction coincidence of described traction sheave 2, permanent magnetic iron 3, bearing 8, coder 4 and plate disc brake 5 or partially overlap, thus realizing minimizing of axial dimension.
In addition, described traction sheave 2 is integral type structure with rotor and brake disc 9.
The motor stator 1 of this detailed description of the invention is wound with symmetrical three-phase alternating current coil, in the coil of motor stator 1, passes into the three-phase alternating-current supply of frequency conversion, in motor air-gap, just produce the magnetic field of the rotation of the symmetry of three-phase; The inner surface of traction sheave 2 posts performance-oriented permanent magnetic iron 3, in motor air-gap, also produces magnetic field; Under the interaction in two kinds of magnetic fields, the traction sheave 2 on motor is rotated.
The principle of work of this detailed description of the invention: when lift car needs up-and-down movement, plate disc brake 5 is opened a sluice gate, in the coil of motor stator 1, pass into variable-frequency power sources, motor rotor rotates together with the steel rope hung on traction sheave 3 groove, and steel rope drags running up and down of lift car; When elevator needs to stop to corresponding floor, just cut off the variable-frequency power sources passed in motor stator 1 coil, traction sheave 2 stops the rotation, and plate disc brake 5 is braked, motor traction sheave 2 is maintained static, also namely makes lift car be fixed on the corresponding position needed.
This detailed description of the invention has saved axial space, reduces axial width, and structure is simple, reasonable in design, practical, solves prior art Problems existing, has wide market application foreground.
More than show and describe groundwork of the present invention and principal character and advantage of the present invention.The technical personnel of the industry should be understood; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and specification sheets just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.
