Description
Technical Field
The utility model belongs to the technical field of the motor head technique and specifically relates to a formula or station formula asynchronous alternating current motor for lawn mower is related to.
Background
With the social progress, the mowing labor is gradually replaced by a mower or a mowing vehicle, and the agricultural mowing efficiency is greatly accelerated. However, the traditional mowing vehicle is basically powered by a fuel engine, on one hand, the fuel engine has high noise, and the hearing of users can be influenced after long-term use; on the other hand, the fuel engine emits tail gas, and the air pollution is serious.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to provide a small, the asynchronous AC motor is used to seat formula or station formula lawn mower that the noise is little.
In order to solve the technical problem, the utility model discloses a technical scheme as follows: asynchronous alternating current motor for seat formula or station formula lawn mower, including both ends open-ended motor housing, motor housing one end is equipped with the rear end cap, keep away from rear end cap one side in the motor housing and be equipped with the stator slot that is used for installing the stator, the stator has the solenoid all around, install the rotor in the stator, the rotor includes that pivot and cover locate the outer cast aluminium rotor of pivot, pivot one end passes the rear end cap and blocks mutually with the axle sleeve gear of stopper, the stopper passes through screw and rear end cap fixed connection.
In foretell seat formula or stand formula are the asynchronous alternating current motor for lawn mower, the gearbox is direct to be integrated with the asynchronous machine front end, has reduced the volume of motor greatly, makes the utility model discloses can be applicable to the less seat formula of volume or stand formula car of mowing, in addition, because motor drive car of mowing, fuel engine drive in the past, the noise reduces by a wide margin, even long-term the use, also can not cause the damage to user's sense of hearing.
Furthermore, an excitation coil is arranged in the center of the interior of the brake, a spring is further arranged around the excitation coil, and an armature is arranged in the spring. The armature iron and the brake disc are attracted through the energizing of the exciting coil to play a releasing role, and the armature iron is pressed through the elastic force of the spring after the exciting coil is powered off to tightly press the friction plate on the brake disc to generate a braking effect. When the mowing vehicle is used, the mowing vehicle is diversified by the terrain, the vehicle is required to have good starting and stopping performance, the braking mode can achieve the characteristic of stopping and walking immediately, the braking distance is shortened compared with a driving braking mode, and the motor braking response is quicker due to the characteristic of electric driving.
To sum up, the utility model discloses compare in the beneficial effect that fuel engine has for traditional lawn mower is:
1. the utility model discloses a cast aluminium rotor shell and pivot shrink fit installation are integrated speed reducer and motor simultaneously, compact structure, and small, be difficult to have accumulative total machining error, suitable as seat formula or station formula car power device of mowing, also difficult noise that produces.
2. The utility model discloses the stopper is equipped with to the rear end, and the braking torque direct action that the stopper produced is in motor shaft, and the braking response is fast, and braking distance is short, is applicable to the meadow and mows the application.
