In the electromagnetic magnet brake 7, the movable iron core 72, that is, the brake shoe 75 is disposed toward the braking surface 9 that is the inner peripheral surface of the cylindrical portion 51.
　このように構成されたインナーロータ型巻上機１では、電動機３が椀状体５の外側に配置されている。椀状体５の内部（径方向内側）には、電磁マグネットブレーキ７が配設されている。電磁マグネットブレーキ７は、椀状体５の径方向内向きの制動面９に対して、径方向内側に位置しており、径方向外側に向けて制動面９を押圧し、椀状体５に制動力を付与する。 In the inner rotor type hoisting machine 1 configured as described above, the electric motor 3 is disposed outside the rod-like body 5. An electromagnetic magnet brake 7 is disposed inside the bowl-like body 5 (in the radial direction). The electromagnetic magnet brake 7 is located on the radially inner side with respect to the radially inward braking surface 9 of the rod-shaped body 5, and presses the braking surface 9 toward the radially outer side to Apply braking force.
　さらに、電磁マグネットブレーキ７の径方向内側であって、椀状体５の回転軸心付近には、綱車１１が設けられている。換言すると、椀状体５の制動面９の径方向内側に配設されている電磁マグネットブレーキ７は、綱車１１の径方向外側に延び出ている。電磁マグネットブレーキ７は、椀状体５のブレーキと、綱車１１のロープ外れ止めとを、兼ねている。図１において、符号Ｄで示される隙間を適切に設計することで、好適な外れ止めが得られる。 Furthermore, a sheave 11 is provided on the inner side in the radial direction of the electromagnetic magnet brake 7 and in the vicinity of the rotational axis of the cage 5. In other words, the electromagnetic magnet brake 7 disposed on the radially inner side of the braking surface 9 of the saddle-shaped body 5 extends outward in the radial direction of the sheave 11. The electromagnetic magnet brake 7 serves as a brake for the saddle-like body 5 and a rope detachment stop for the sheave 11. In FIG. 1, a suitable detachment prevention can be obtained by appropriately designing the gap indicated by the symbol D.
　椀状体５は、軸方向一側を開口とする椀状に構成されている。椀状体５は、その一部として、回転軸部分５２を備えている。回転軸部分５２は、椀状体５の回転軸線ＲＡに沿って底部５３から軸方向一側に突出した円柱状の部分である。回転軸線ＲＡは、回転軸部分５２の一部を通っている。綱車１１は、回転軸部分５２の突出端部に取り付けられている。一例であるが、綱車１１は、椀状体５とは別に成形されており、すなわち、椀状体５とは別体である。綱車１１に、回転軸部分５２が挿通されている。また、綱車１１には、かごなどに接続される巻上ロープ１３が巻き掛けられている。 The bowl-shaped body 5 is configured in a bowl shape having an opening on one side in the axial direction. The bowl-like body 5 includes a rotating shaft portion 52 as a part thereof. The rotation shaft portion 52 is a columnar portion that protrudes from the bottom 53 to the one side in the axial direction along the rotation axis RA of the bowl-shaped body 5. The rotation axis RA passes through a part of the rotation shaft portion 52. The sheave 11 is attached to the protruding end of the rotating shaft portion 52. As an example, the sheave 11 is formed separately from the cage 5, that is, separate from the cage 5. A rotary shaft portion 52 is inserted through the sheave 11. Further, a hoisting rope 13 connected to a car or the like is wound around the sheave 11.
　椀状体５は、ベアリング６を介してハウジング２に組付けられており、回転軸部分５２に固定された綱車１１が椀状体５と一体的に、回転される。なお、椀状体５の底部５３における電磁マグネットブレーキ７の側方、すなわち綱車１１と反対側には、保守用穴５４が設けられていてもよい。 The cage 5 is assembled to the housing 2 via the bearing 6, and the sheave 11 fixed to the rotating shaft portion 52 is rotated integrally with the cage 5. A maintenance hole 54 may be provided on the side of the electromagnetic magnet brake 7 at the bottom 53 of the bowl 5, that is, on the side opposite to the sheave 11.
　このように構成されたインナーロータ型巻上機１では、かごの停止時には、コイル７３への給電が停止される。そこで、可動鉄心７２が、図３に示されるように、ブレーキバネ７４の付勢力により固定鉄心７１から離間される。これにより、可動鉄心７２がブレーキシュー７５を介して円筒部５１の制動面９に押圧され、制動力が椀状体５に付与される。また、かごの昇降時には、コイル７３に給電される。そこで、可動鉄心７２が、図４に示されるように、ブレーキバネ７４の付勢力に抗して固定鉄心７１に磁気吸引される。これにより、可動鉄心７２、すなわちブレーキシュー７５が円筒部５１の制動面９から離間し、椀状体５に対する制動力が解除される。そこで、ステータコイル３２に給電されて電動機３が作動し、椀状体５が回転駆動される。そして、綱車１１が椀状体５と共に回転駆動され、巻上ロープ１３が走行され、かごが昇降する。 In the inner rotor type hoisting machine 1 configured as described above, the power supply to the coil 73 is stopped when the car is stopped. Therefore, the movable iron core 72 is separated from the fixed iron core 71 by the urging force of the brake spring 74, as shown in FIG. As a result, the movable iron core 72 is pressed against the braking surface 9 of the cylindrical portion 51 via the brake shoe 75, and a braking force is applied to the bowl-shaped body 5. In addition, when the car is raised and lowered, power is supplied to the coil 73. Therefore, the movable iron core 72 is magnetically attracted to the fixed iron core 71 against the urging force of the brake spring 74, as shown in FIG. As a result, the movable iron core 72, that is, the brake shoe 75 is separated from the braking surface 9 of the cylindrical portion 51, and the braking force on the bowl-shaped body 5 is released. Therefore, electric power is supplied to the stator coil 32 to actuate the electric motor 3, and the cage 5 is rotationally driven. Then, the sheave 11 is rotationally driven together with the cage 5 so that the hoisting rope 13 travels and the car is moved up and down.
　以上のように構成されたインナーロータ型巻上機１によれば、これまで電動機３側に向けていた椀状体５の開口側、すなわち凹部を、綱車１１側に向けることにより電磁マグネットブレーキ７を綱車１１側に配置することが可能となった。また、電磁マグネットブレーキ７が、固定鉄心７１、可動鉄心７２およびコイル７３からなる電磁マグネットとブレーキバネ７４との組み合わせで構成される直動型のブレーキである。これにより、巻上ロープ１３に干渉しない範囲で電磁マグネットブレーキ７を大型化できるため、大電流により電磁マグネットブレーキ７の動作力を増やすことができる。また、従来必要であったブレーキアームが不要となるので、電磁マグネットブレーキ７のハウジング２からの軸方向の突出が抑えられ、インナーロータ型巻上機１の軸方向の薄型化が図られる。 According to the inner rotor type hoisting machine 1 configured as described above, an electromagnetic magnet brake is achieved by directing the opening side, that is, the concave portion of the saddle-like body 5 facing the electric motor 3 side so far to the sheave 11 side. 7 can be arranged on the sheave 11 side. The electromagnetic magnet brake 7 is a direct-acting brake configured by a combination of an electromagnetic magnet including a fixed iron core 71, a movable iron core 72, and a coil 73 and a brake spring 74. Thereby, since the electromagnetic magnet brake 7 can be enlarged in the range which does not interfere with the hoisting rope 13, the operating force of the electromagnetic magnet brake 7 can be increased by a large current. Further, since the brake arm which has been conventionally required is not required, the axial projection of the electromagnetic magnet brake 7 from the housing 2 is suppressed, and the axial thinning of the inner rotor type hoist 1 is achieved.
　さらに、これにより、素材選定、熱設計および保守性の観点で好適なインナーロータ型巻上機１を提供することができる。すなわち、素材選定の観点では、スペースの制約が取り払われたため、電磁マグネットブレーキ７の形状の自由度が上がり、加工性のよい丸型のブレーキなどの採用が可能となる。また、電磁マグネットブレーキ７を大型化することにより、安価な素材（一般構造用圧延鋼板など）の採用が容易となる。また、熱設計の観点では、電磁マグネットブレーキ７の一部が、ハウジング２から綱車１１側に露出するため、放熱性がよく、大電流により電磁マグネットブレーキ７の動作力を増やし、電線量を減らすことが容易である。また必要であれば、巻上ロープ１３と干渉しない範囲で放熱フィンなどの放熱対策要部品を電磁マグネットブレーキ７に取り付けることにより、容易に放熱することが可能となる。さらに保守性の観点では、電磁マグネットブレーキ７が綱車１１側に配置されているため、綱車１１をかご側に配置するレイアウトが可能である。また、もし綱車１１と反対側から電磁マグネットブレーキ７をメンテナンスする必要がある場合、椀状体５（構造によってはハウジング２を含む）に部分的に穴を空けておくことで、綱車１１と反対側から電磁マグネットブレーキ７をメンテナンスすることも許容できる。また電磁マグネットブレーキ７が綱車１１側に配置され、かつ軸方向に関して綱車１１とラップする場合、ブレーキ本体の構造部品で綱車１１の周囲を覆うことにより、ブレーキ本体をロープ外れ止めとし、またカバーを取り付けるための土台とすることも可能である。 Furthermore, this makes it possible to provide an inner rotor type hoisting machine 1 that is suitable in terms of material selection, thermal design, and maintainability. That is, from the viewpoint of material selection, since the space restriction is removed, the degree of freedom of the shape of the electromagnetic magnet brake 7 is increased, and it becomes possible to employ a round brake having good workability. In addition, by increasing the size of the electromagnetic magnet brake 7, it is possible to easily adopt an inexpensive material (such as a general structural rolled steel plate). From the viewpoint of thermal design, part of the electromagnetic magnet brake 7 is exposed from the housing 2 to the sheave 11 side, so that heat dissipation is good, the operating force of the electromagnetic magnet brake 7 is increased by a large current, and the amount of wires is reduced. Easy to reduce. In addition, if necessary, heat dissipation countermeasure parts such as heat dissipation fins can be attached to the electromagnetic magnet brake 7 as long as they do not interfere with the hoisting rope 13 and heat can be easily radiated. Furthermore, from the viewpoint of maintainability, since the electromagnetic magnet brake 7 is disposed on the sheave 11 side, a layout in which the sheave 11 is disposed on the car side is possible. Further, if it is necessary to maintain the electromagnetic magnet brake 7 from the side opposite to the sheave 11, a sheave 11 (including the housing 2 depending on the structure) is partially opened so that the sheave 11 Maintenance of the electromagnetic magnet brake 7 from the opposite side is also permissible. Further, when the electromagnetic magnet brake 7 is arranged on the sheave 11 side and wraps with the sheave 11 in the axial direction, the brake body is made to prevent the rope from coming off by covering the periphery of the sheave 11 with the structural parts of the brake body, It can also be used as a base for attaching the cover.
　また機械室レスエレベータにおいて、巻上機の綱車を手前にして配置するという要求に対しては、綱車と反対側の椀状体内部にブレーキが設置されるため、綱車側からのブレーキ保守ができないという問題が生じ得る。これに対し、本実施の形態では、電磁マグネットブレーキ７を綱車１１側に配置することにより、このような保守性の問題を回避することも可能であろう。 In addition, in a machine room-less elevator, a brake is installed inside the saddle on the opposite side of the sheave to meet the requirement that the sheave of the hoist is placed in front. There may be a problem that maintenance is not possible. On the other hand, in the present embodiment, it is possible to avoid such a problem of maintainability by arranging the electromagnetic magnet brake 7 on the sheave 11 side.
　なお、上記実施の形態１では、電動機の電機子を枠状体と別体に構成しているが、枠状体が電動機の電機子を兼用してもよい。 In Embodiment 1 described above, the armature of the motor is configured separately from the frame-shaped body, but the frame-shaped body may also serve as the armature of the motor.
