Abstract
A stator has such constitution that a part of a connecting board 3 is projected inside the molded stator of a motor, and that electronic parts such as a magnetic sensor 4, a resistor, a thermal fuse 9, etc., are mounted. By this constitution, the improvement of the reliability of soldering and the building of a thermal protector into a motor become possible, and the influence of the magnetic fluxes of winding of a magnetic sensor, etc., can be lightened.
Description
The present invention relates to be used for stator as the motor of various families electrical article drive source.
Below, the stator of motor in the past is described with reference to the accompanying drawings.Fig. 3 is the longitudinal sectional drawing of motor in the past.Coil 2 is used in the stator core 1 of insulation resin around being added in, and be equipped with each phase coil and be connected, and revolution is installed is detected the printed chassis 3 of using electronic components such as transducer 4, with inserting rotor finished parts 6 again in the stator 5 of the resin with electric insulating quality with above-mentioned base plate mold pressing encapsulation, just make the motor finished product behind the rigid bearing 7 on bearing bracket stand at rigid bearing.
Yet above-mentioned structure is in the past reinstated hot press moulding with stator coil one and is shaped because of welding such as electronic component are loaded on printed chassis, is difficult to guarantee the reliability of welding portion, again because high temperature is adorned also difficulty of the such temperature protective device of fuse in wanting.Revolution is detected when being contained on the printed chassis when being equal to Magnetic Sensor, can not fully ensure and the distance of coil, influenced by the leakage magnetic flux of coil so also exist, Magnetic Sensor is the problem of malfunction sometimes.
The objective of the invention is and will address the above problem, improve the reliability of bump, can in the dress temperature protective device, and reduce the magnetic flux influence of Magnetic Sensor etc.
For realizing this purpose, the present invention has the structure that a part that makes the terminal block that is loaded on the stator coil finished parts is stretched out the mold pressing package outside.
Utilize this structure, except that each phase connection portion of coil and power unit, can both extend out to the mold pressing package outside, can improve the reliability of bump, and dress temperature protective device in the energy that becomes, the influence that can also alleviate coil fluxs such as Magnetic Sensor.
Fig. 1 is the part sectioned view of the motor of one embodiment of the invention;
Fig. 2 is the oblique view of the stator of one embodiment of the invention;
Fig. 3 is the part sectioned view of motor in the past.
The number in the figure implication is as follows.1: stator core, 2: coil, 3: terminal block, 4: Magnetic Sensor, 5: stator, 6: rotor finished parts, 7: bearing, 8: resistance, 9: Thermal Cutoffs, 10: hole.
Below, referring to description of drawings one embodiment of the invention.
Fig. 1 is the longitudinal sectional drawing of embodiment of the invention motor.
Fig. 2 is the oblique view of the stator of the embodiment of the invention.Among Fig. 1, be added with in the stator core 1 on the coil finished parts of coil 2, load onto terminal block 3, with making stator 5 after the resin-molded encapsulation with insulating properties.At this moment, the part of terminal block 3 has the structure of protruding to this diameter of stator bore side.
Among Fig. 2, on the terminal block that this internal side diameter protrudes, Magnetic Sensor 4 is installed, in the time of resistance 8 these electronic components, the such temperature protective device of Thermal Cutoffs 9 can also be installed.The hole 10 that the bearing portion 7 of rotor finished parts 6 can pass through when having assembling again.
In sum; the present invention allows the part of terminal block protrude to internal side diameter in the diameter of stator bore side with resin-molded encapsulation; and electric parts, the electronic component of installation necessity thereon; can not only improve the reliability of bump; and can also interiorly adorn temperature protective device; leave the distance of coil, the influence that can also alleviate coil flux owing to can fully ensure Magnetic Sensor etc.
