Abstract
The utility model relates to a variable-frequency motor for a roller way, wherein the variable-frequency motor is composed of a base, an end cover, a bearing outer cover, a stator iron core with a winding, a rotator shaft, and a cast-aluminum rotor iron core. And the variable-frequency motor is characterized in that the number of poles of the stator iron core with a winding is 10 to 24. Advantages of the provided variable-frequency motor are as follows: the stator iron core with a winding is processed by a special electromagnetic design, so that the motor can be ensured to have a large locked-rotor torque and a low thermal load; the rotator shaft employs a thick shaft extension structure, thereby providing the large locked-rotor torque output for the motor; the motor can directly drive the roller way equipment; and the motor with the simplified structure can be installed conveniently and thus the roller way equipment cost can be reduced substantially.
Description
Technical field
The utility model belongs to the threephase asynchronous technical field, particularly relates to a kind of roller-way variable-frequency motor.
Background technology
At present, many production lines of each large steel mill all need be used roller-way equipment, but because of the requirements of installation space restriction, this roller-way equipment requirement power source---electric machines for roller can directly drive roller-way, also to guarantee simultaneously to obtain large torque output, in order to satisfy the needs of roller-way equipment, designed the thick shaft extension roller-way variable-frequency motor of direct driving roller, thick shaft extension electric machines for roller locked-rotor torque through particular design can directly drive roller greatly, conveniently installs, can guarantee electric machines for roller reliability service in the use of each large steel mill.
Summary of the invention
The utility model provides a kind of roller-way variable-frequency motor for solving the technical problem that exists in known technology, and this motor rotation blockage torque is large, can directly drive roller.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
A kind of roller-way variable-frequency motor comprises support, end cap, bearing end cover, winding stator core is arranged, armature spindle, cast-aluminum rotor iron core that it is characterized in that: the number of poles that winding stator core is arranged is 10-24 utmost points.
The utility model can also adopt following technical scheme:
It is described that the number of poles of winding stator core is arranged is 12 utmost points.
It is described that the number of poles of winding stator core is arranged is 16 utmost points.
It is described that the number of poles of winding stator core is arranged is 20 utmost points.
Advantage and the good effect that the utlity model has are: after the utility model has adopted above technical scheme, namely there is winding stator core to design through special electromagnetic, guarantee that motor has larger locked-rotor torque and lower heat load, armature spindle adopts thick shaft extension structure, can be motor provides the output of larger locked-rotor torque, motor can directly drive roller-way equipment, designs simplification, easy for installation, but and then decrease roller-way equipment cost.
Description of drawings
Fig. 1 is structural representation of the present utility model.
In figure: 1, support; 2, winding stator core is arranged; 3, cast-aluminum rotor iron core; 4, armature spindle; 5, end cap; 6, bearing end cover.
Embodiment
For further understanding summary of the invention of the present utility model, Characteristic, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
See also Fig. 1, a kind of roller-way variable-frequency motor, comprise support 1, end cap 5, bearing end cover 6, winding stator core 2, armature spindle 4, cast-aluminum rotor iron core 3 are arranged, the number of poles that winding stator core is arranged is 10 utmost points-24 utmost points, in the present embodiment, described have the number of poles of winding stator core to be preferably 10 utmost points or 12 utmost points or 16 utmost points or 20 utmost points or 24 utmost points.Rotor punching flute profile selection of small flute profile by strengthening rotor resistance, guarantees that motor has 3.0 times of larger locked-rotor torque multiples (〉), appropriate design stator winding installation data, lengthen iron core, the wire gauge overstriking, realize lower electromagnetic load with lower heat load (less than 1000A
2/ (cm mm
2)).
The armature spindle diameter of shaft of each seat No. sees the following form:
Although the above is described preferred embodiment of the present utility model by reference to the accompanying drawings; but the utility model is not limited to above-mentioned embodiment; above-mentioned embodiment is only schematic; be not restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; not breaking away from the scope situation that the utility model aim and claim protect, can also make a lot of forms, within these all belong to protection range of the present utility model.
