Abstract
The invention relates to a mouse-cage type tapered rotor electromotor, and the main design of the electromotor comprises that: an inner cavity of a stator and the surface of a rotor of the electromotor are tapered; the tapered rotor is simultaneously used as a brake. After a triphase winding of the stator is connected with a power supply, an axial magnetic pull force is generated to allow the rotor to generate axial movement; an axial braking spring is drawn; and the tapered rotor is pushed to enable the normal operation of the electromotor; when the electromotor is needed to be stopped, the power supply of the electromotor is powered off; and then the axial magnetic pull force disappears; under the action of resilience of the spring, the tapered rotor rapidly brakes to allow the rotor to stop rotating immediately, thereby realizing the function of rapid braking.
Description
Technical field
The present invention relates to a kind of motor, particularly a kind of conical rotor motor.
Background technology
A brake disc is mostly installed in the braking of motor commonly used on the main shaft of motor, brake disc itself can make the moment of inertia of motor increase, thereby motor is in the process of running or expend extra energy, and because brake disc itself has certain shape structure of thinking, the space that occupation ratio is bigger, can increase the size of motor virtually, consumptive material is many, increases the material cost of making motor.
Summary of the invention
The purpose of this invention is to provide a kind of mouse-cage type tapered rotor electromotor, motor commonly used adopts brake structural to increase the size of motor and the problem of consumptive material, and expends extra energy.
The objective of the invention is to be achieved through the following technical solutions:
A kind of mouse-cage type tapered rotor electromotor, comprise front end housing, rear end cap, casing and pass the main shaft of casing, in casing inside stator and rotor are installed, rotor is installed on the main shaft, described rotor is tapered, and stator also matches with rotor and makes conical internal cavity, and the mating surface of rotor and stator is made rubbing surface.
Being further designed to of this motor is provided with tripping spring on the electric machine main shaft of the front end of rotor, the other end of tripping spring is connected on the front end housing.
Being further designed to of this motor, tripping spring is connected with front end housing by the butterfly spring group, and is provided with cylindrical roller thrust bearing in the middle of front end housing.
Being further designed to of this motor is provided with brake disc in rear end cap inside.
Can make the lifting transmission device in rapid, accurate, the safe braking of when walking; The starting torque height; Margin of temperature rise is big, is suitable for Fraquent start and braking; Safe and reliable; Be applicable to indoor or outdoor various evil condition; Compact conformation, volume is little, has higher economy.
Description of drawings
With embodiment the present invention is described in further detail with reference to the accompanying drawings below.
Fig. 1 is the structure chart of the described mouse-cage type tapered rotor electromotor of the embodiment of the invention.
Among the figure:
1, front end housing; 2, rear end cap; 3, casing; 4, stator; 5, rotor; 6, tripping spring; 7, butterfly spring group; 8, cylindrical roller thrust bearing; 9, brake disc; 10, main shaft.
Embodiment
As shown in Figure 1, the described a kind of mouse-cage type tapered rotor electromotor of the embodiment of the invention, comprise front end housing 1, rear end cap 2, casing 3 and pass the main shaft 10 of casing 3, in casing 3 inside stator 4 and rotor 5 are installed, rotor 5 is installed on the main shaft 10, described rotor 5 is tapered, and stator 4 also matches with rotor 5 and make conical internal cavity, and the mating surface of rotor 5 and stator 4 is made rubbing surface.
Being further designed to of this motor is provided with tripping spring 6 on the electric machine main shaft 10 of the front end of rotor 5, the other end of tripping spring 6 is connected on the front end housing 1.
Being further designed to of this motor, tripping spring 6 is connected with front end housing 1 by butterfly spring group 7, and is provided with cylindrical roller thrust bearing 8 in the middle of front end housing.
Being further designed to of this motor is provided with brake disc 9 in rear end cap 3 inside.
After stator 4 three phase winding energized, will produce axial magnetic pull, rotor 5 is produced move axially, draw back axial tripping spring 6, push cone rotor 5 open, motor is normally moved.When the needs motor stops, the motor power outage, this moment, axial magnetic pull disappeared, under the effect of spring 6 restoring forces, the conical internal cavity friction of pulling cone rotor 5 and stator 4, thereby reach cone rotor 5 purpose of braking rapidly, rotor 5 is stopped operating immediately, thereby realize the function of fast braking.
Can make the lifting transmission device in rapid, accurate, the safe braking of when walking; The starting torque height; Margin of temperature rise is big, is suitable for Fraquent start and braking; Safe and reliable; Be applicable to indoor or outdoor various evil condition; Compact conformation, volume is little, has higher economy.
