Abstract
The utility model relates to a large inertia motor, which belongs to the technical field of motor production and manufacturing. The large inertia motor comprises a motor main body and a rotary shaft. Besides, the rotary shaft is fixedly equipped with an inertia device for increasing rotary inertia of the motor. The utility model with comparatively low power consumption is capable of improving starting performance of the motor and resolving the problems that existing motors are comparatively difficult to be started when load is comparatively large, or the motors with relatively large torques need high power consumption and the like.
Description
Technical field
The utility model relates to a kind of big inertia motor, belongs to the technical field that motor is manufactured.
Technical background
When the load that connects when motor was big, the torque drag from load suffered during electric motor starting will be bigger, and will there be the problem that starts difficulty in motor.For solving the problem of electric motor starting difficulty, can adopt the bigger motor of staring torque in the prior art, but adopt the bigger motor of staring torque behind electric motor starting, then can have the bigger problem of power consumption.
Summary of the invention
The utility model purpose is to provide a kind of startability that improves motor, and the less big inertia motor of power consumption, and solve load that existing motor exists and started difficulty when big, or problem such as the bigger motor power consumption of moment is bigger.
Above-mentioned technical purpose of the present utility model mainly solves by the following technical programs: it comprises motor body and rotating shaft, is set with in the described rotating shaft in order to increase the inertia device of motor moment of inertia.Wherein, in the rotating shaft of motor, be provided with in order to increase the inertia device of motor moment of inertia, starter motor makes motor obtain a bigger moment of inertia before the motor-driven load, and then motor is connected with load driving, thereby make motor be easy to drive equipment than heavy load, thereby overcome the problem of electric motor starting difficulty, also need not adopt the motor of big staring torque, to reduce power consumption.
As preferably, the rear end of described rotating shaft extends to the outside, rear end of motor body, and described inertia device is arranged at the rear end of rotating shaft.Wherein, the inertia device is arranged on the rear end that rotating shaft extends to outside, motor body rear end, it can reduce the interference of inertia device to rotor and stator on the one hand, also is convenient to the assembling of motor integral body on the other hand.
As preferably, described rotating shaft rear end also is provided with the heat radiation wind wheel, and described motor body rear end is provided with guard shield, and described guard shield is enclosed in inertia device and heat radiation wind wheel in the cavity that motor body rear end and guard shield surround.Wherein, the heat dispersion that the heat radiation wind wheel can improve motor is set in the rotating shaft rear end, in addition, guard shield then can play dustproof to inertia device and wind wheel, causes the problem of motor oscillating to avoid laying dust on inertia device and wind wheel.
As preferably, described inertia device is a disk-like structure.Wherein, the inertia device also can adopt column structure.
As preferably, adopt radial screw to fix between described inertia device and the rotating shaft, thereby guarantee the reliability that is connected between inertia device and the rotating shaft.
As preferably, described inertia device is formed with axially extended shoulder, and screw passes shoulder inertia device and rotating shaft are fixed together, thereby is convenient to the assembling between inertia device and the rotating shaft.
Therefore, the utlity model has the startability that can improve motor, and power consumption is less, assembles characteristics such as more convenient.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
Embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment 1: as shown in Figure 1, comprise motor body 1 and rotating shaft 2, the rear end of rotating shaft 2 extends to the outside, rear end of motor body 1, the rear end of rotating shaft is set with the inertia device 3 in order to the disk-like structure that increases the motor moment of inertia, inertia device 3 is formed with axially extended shoulder 6, radial screw passes shoulder inertia device 3 and rotating shaft 2 is fixed together, the rear end of rotating shaft 2 also is provided with heat radiation wind wheel 4, motor body 1 rear end is provided with guard shield 5, and guard shield 5 is enclosed in inertia device 3 and heat radiation wind wheel 4 in the cavity that motor body 1 rear end and guard shield 5 surround.
In the rotating shaft of motor, be provided with in order to increase the inertia device of motor moment of inertia, starter motor makes motor obtain a bigger moment of inertia before the motor-driven load, and then motor is connected with load driving, thereby make motor be easy to drive equipment than heavy load, thereby overcome the problem of electric motor starting difficulty, also need not adopt the motor of big staring torque, to reduce power consumption.
