Abstract
The utility model discloses the motor technology field and discloses a motor rotor shaft comprising a rotor installation segment and an output connection segment. Fans are arranged on one side of the output connection segment and are near the rotor installation segment. Through the mounted fans, temperature rise of the motor is greatly reduced, so that the motor can continually operate.
Description
Technical field
The utility model relates to technical field of motors, relates in particular to a kind of motor rotor shaft.
Background technology
Along with development and national economy, energy problem has more and more obtained people's attention, develops energy-efficient motor product, is key subjects of machine field.
Existing motor is when operation, if load speed is lower, when torque was big, the operating temperature of motor can continue to increase.Therefore the operation at motor can only be a discontinuity, and not so too high temperature can make electrical machinery life shorten.
The utility model content
The purpose of this utility model is in order to address the above problem, a kind of motor rotor shaft to be provided, in the hope of to reducing the temperature of motor under the operating mode of big torque.
The technical scheme that the utility model is taked is:
A kind of motor rotor shaft comprises rotor construction section, output linkage section, it is characterized in that, near a side of described rotor construction section fan blade is installed at described output linkage section.
Further, the distance between described fan blade and the described rotor construction section end is 5 to 10mm.
Further, the rotor of described rotor construction section installation is a skewed rotor.
The beneficial effects of the utility model are:
The setting of fan blade greatly reduces motor temperature, makes the motor can continuous operation.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.
Label in the accompanying drawing is:
1. motor rotor shaft; 2. rotor construction section;
3. output linkage section; 4. fan blade;
5. skewed rotor.
Embodiment
Elaborate below in conjunction with the embodiment of accompanying drawing to the utility model motor rotor shaft.
Referring to accompanying drawing 1, motor rotor shaft 1 comprises rotor construction section 2 and output linkage section 3, near a side of rotor construction section 2 fan blade 4 is installed at output linkage section 3, and fan blade 4 is the iron axial-flow leaf of the big acute angle of major diameter, increases wind flow.Have air inlet and air outlet at the two ends of motor.Distance between the end of fan blade 4 and rotor construction section 2 is 5 to 10mm.Simultaneously, the vibration when reducing motor rotation, the rotor of installing on rotor construction section 2 is a skewed rotor 5.
The above only is a preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.
Claims (3)
