ものは別電源を必要とするため、高価となったり、大型
化するなどの欠点がある。As a mechanical braking method, a method using an electromagnetic brake is known. However, devices equipped with such an electromagnetic brake require a separate power source, and therefore have drawbacks such as being expensive and bulky.
そこで、固定子の磁力を利用して制動力を得るようにし

ている。Therefore, prior art is known in which braking force is obtained using the magnetic force of the stator. (Jitko Showa 60-37016
No. 100) This prior art is explained according to Fig. 5.
101 is a casing, and 101 is a stator consisting of a stator core 102 and a stator winding 103. This stator 101
A fixed core 104 is integrally provided on one end surface of a stator core 102, and the stator winding 103 is commonly inserted into the wire type grooves of both cores 102 and 104. The blank plate of the fixed core 104 is formed by laminating thin plates made of the same material as the blank plate of the stator core 102, and the inner peripheral end of each blank plate is bent in the axial direction to form a truncated conical magnetic pole face 105. It consists of

制動面１）３が形成されている。On the other hand, a rotating shaft 107 supporting the rotor 106 has a magnetic pole surface 1 having a shape corresponding to the magnetic pole surface 105 of the fixed iron core 104.
08 is provided so as to be movable only in the axial direction. On one end surface of this movable iron core 109,
A rotary brake plate 1) 1 to which a brake lining 1) 0 is attached is provided, and a fixed brake surface 1 is provided on the inner surface of the bracket 1) 2 facing the brake lining 1) 0 of the rotary brake plate 1) 1. )3 is formed.
１）４ は可動鉄心１０９ と回転子１０６ との間に
配装された押圧バネであり、これは、可動鉄心１０９を
常時ブラケット１）２（Ｉ！Ｉに押圧するものである。1) 4 is a pressing spring disposed between the movable iron core 109 and the rotor 106, which constantly presses the movable iron core 109 against the bracket 1) 2 (I!I).
上記先行技術の作用を説明する。The operation of the above prior art will be explained.
電動機の始動に際し、固定子巻線１０３を励磁すると、
回転磁界が発生し、固定鉄心１０４ と可動鉄心１０９
との間に磁気吸引力が生じる。これにより可動鉄心１
０９が押圧バネ１）４の付勢力に抗して固定鉄心１０４
側に吸引されて、制動用ライニング１）０を固定制動面
１）３から引離す。可動鉄心１０９は回転軸１０７０段
部に係止されて止まる。こうして、電動機は運転状態と
なる。When the stator winding 103 is excited when starting the electric motor,
A rotating magnetic field is generated, and the fixed iron core 104 and the movable iron core 109
A magnetic attraction force is generated between the two. As a result, movable iron core 1
09 is the fixed iron core 104 against the urging force of the pressing spring 1)4.
The brake lining 1)0 is pulled away from the fixed brake surface 1)3 by suction to the side. The movable iron core 109 is stopped by being locked to the stepped portion of the rotating shaft 1070. In this way, the electric motor is put into operation.
次に、電源を遮断して固定子巻線１０３の励磁を解けば
、固定鉄心１０４ と可動鉄心１０９ との間の磁器吸
引力がなくなるので、押圧バネ１）４の付勢力が働き、
可動鉄心１０９はグラゲット１）２側に移動する。こう
して、制動用ライニング１）０が固定制動面１）３に押
圧されて、可動鉄心１０９を介して回転軸１０７に制動
がかけられる。Next, when the power is cut off and the excitation of the stator winding 103 is released, the magnetic attraction force between the fixed core 104 and the movable core 109 disappears, so the biasing force of the pressing spring 1) 4 is activated.
The movable iron core 109 moves to the graget 1) 2 side. In this way, the braking lining 1) 0 is pressed against the fixed braking surface 1) 3, and braking is applied to the rotating shaft 107 via the movable iron core 109.

欠点があった。C1 Problems to be Solved by the Invention However, according to the above-mentioned prior art braking device, a fixed core 104 separate from the stator core 102 is required when molding the stator 101, and furthermore, a conical magnetic pole surface is formed.
Since it is necessary to sequentially bend the teeth of the fixed core 104 while changing the diameter, the processing becomes complicated. In addition, the fixed core 104
The stator winding 103 protrudes to the inner peripheral side of the stator core 102, making it difficult to wind the stator winding 103. Furthermore, since the movable core 109 and the pressure spring 104 rotate together with the rotary shaft 107, a corresponding weight is added to the rotary shaft 107 and damage to the movable core 109 and the pressure spring 1)4 is likely to occur. Movable iron core 109
Since there is a gap between the fixed iron core 104 and the fixed iron core 104, the electromagnetic force generated by the rotating magnetic field cannot be used effectively, and therefore the pressing force of the pressing spring 1) 4 is limited, so there is a drawback that the braking force cannot be increased.

たことにある。d. Means for Solving the Problems In order to solve the above-mentioned problems, the present invention supports a brake plate body that rotates together with the rotor of an electric motor on a rotating shaft, and a brake plate body that faces the friction surface of the brake plate body. An armature having a friction surface and abutted against the inner diameter end face of the stator with a predetermined gap where the electromagnetic attraction force of the stator acts is supported on a stationary body so as to be movable in the axial direction, The present invention is provided with a biasing means for pressing the armature against the brake plate body only when the power is de-energized.

する。e. Operation When the stator of the motor is excited, the attractive force of the stator acts, and the armature moves toward the stator against the urging force of the urging means. The friction surface of the armature is then pulled away from the brake plate. In this way, the rotating shaft of the electric motor rotates.

接して制動作用が働き、回転軸の回転を停止させる。Next, when the power to the stator of the electric motor is cut off, the magnetic attraction force of the stator disappears, so the biasing force of the biasing means acts and the armature is drawn toward the brake plate. In this way, the friction surface of the armature comes into pressure contact with the brake plate, causing a braking action and stopping the rotation of the rotating shaft.

次に上記電動機の制動装置の作用を説明する。Next, the operation of the braking device for the electric motor will be explained.

よって回転子６は回転を始め、駆動状態となる。When the electric motor is operated, when the power is turned on, the stator winding 5 is excited and a rotating magnetic field is generated, and the stator core 4 becomes a magnetic path through which part of the magnetic flux of the rotating magnetic field passes.
A magnetic attraction force acts between the armature 14 and the armature 14 . As a result, the armature 14 is attracted to the stator core 4 side against the biasing force of the leaf spring 17 and moves in the axial direction, and the armature 14 is attracted to the corner of the stator core 4. In this way, the friction surface 16a separates from the brake lining 13 due to the movement of the nermate 14, and the rotating shaft 7 becomes free. Then, the rotor 6 begins to rotate due to the rotating magnetic field created by the stator 3, and becomes in a driving state.

is separated from the brake lining 13. Thereby,
The rotating shaft 7 is released from the braking state and starts rotating. On the other hand, when the stator is de-energized by cutting off the power supply, the armature 14 is pulled back by the biasing force of the pin spring 19, and the friction surface 16a comes into pressure contact with the brake lining 13, resulting in a braking state.

Effects of the Invention As described above, according to the braking device for an electric motor according to the present invention, the armature can be provided separately from the rotating shaft, and a conventional stator can be used, so there is no unnecessary noise during rotation. It is possible to improve work efficiency and reduce manufacturing costs without adding any load. Further, since the armature 14 is attracted to the corner of the stator core 4, the electromagnetic attraction force due to the rotating magnetic field can be effectively used, and the biasing force of the temporary spring etc. can be strengthened, so that the braking force can be improved.
