The capacitor cap of the asynchronous motor is reasonable in structural design and capable of effectively protecting a capacitor.
Description
Technical field
The utility model belongs to motor parts technical field, relates to the capacitor cover of a kind of capacitor cover, particularly a kind of asynchronous motor.
Background technology
Capacitor is almost indispensable energy-storage travelling wave tube in electronic circuit, the start-up capacitance of motor generally is only limited to load motor, electric motor starting is that Inside coil produces rotating magnetic field with the prerequisite that running is set up, this starting capacitance is serially connected on the auxiliary winding of single-phase motor, shifts to alternating voltage for motor provides starting.
Existing starting capacitance is set directly at the hull outside of motor, easily is subjected to external influence, causes the useful life of electric capacity short, needs often electric capacity to be changed, and operation is bothersome requires great effort, and has increased the maintenance cost of motor.
Summary of the invention
The purpose of this utility model is to have the problems referred to above for existing technology, has proposed a kind of reasonable in design, can effectively protect the capacitor cover of the asynchronous motor of electric capacity.
The purpose of this utility model can realize by following technical proposal:
a kind of capacitor cover of asynchronous motor, be arranged on the housing of motor, it comprises that an end has the tubular body of opening, it is characterized in that, described body comprises sidepiece and bottom, described sidepiece is by the first side, second side adjacent with the first side, three side adjacent with the second side, and four side adjacent with the 3rd side consists of, described the first side and the 3rd side are oppositely arranged, described the second side and the 4th side are oppositely arranged, described bottom is curved, and described bottom is along the second side even transition to the four sides.
In the capacitor cover of above-mentioned asynchronous motor, the opening part of described body has the connecting portion that is connected with motor field frame, and described connecting portion stretches out for several and along the plane that described opening forms.
In the capacitor cover of above-mentioned asynchronous motor, described connecting portion is 6, lays respectively on the second side and the 4th side.
In the capacitor cover of above-mentioned asynchronous motor, have 4 connecting portions on described the second side, have 2 connecting portions on described the 4th side.
In the capacitor cover of above-mentioned asynchronous motor, has chamfering between described the first side and the second side, have chamfering between described the second side and the 3rd side, have chamfering between described the 3rd side and the 4th side, have chamfering between described the 4th side and the first side.
Compared with prior art, the capacitor cover of this asynchronous motor has the following advantages: reasonable in design, can play a good protection to electric capacity, and manufacturing and easy for installation because its bottom is curved, can not damage human body, and security performance is good.
