no. 1 approach

[0025] As follows, while referring to figure 1 and figure 2 , while describing in detail the field device and the non-excitation service brake according to the first embodiment of the present invention.

[0026] figure 1 The non-excited working brake 1 shown uses the excitation device 2 to operate, in figure 1 The end portion on the left side is attached to the rear case 3 a of the servo motor 3 . Hereinafter, the direction in which the rear shell 3a is located with respect to the non-excitation working brake 1 (in figure 1 The left side in the middle) is called "first direction", and the direction opposite to this direction is called "second direction". In addition, when there are two members, the member located in the first direction is named "one (member)", and the member located in the second direction is named "another (member)". Fill in the name of the component in "(component)".

Abstract

The invention provides a small excitation device (2) which can be simply manufactured and can fully ensure coil space. The excitation device (2) is provided with a cylindrical outer pole member (7) and an inner pole member (6) embedded into the hollow part of the outer pole member (7). The inner pole member (6) has an annular recessed portion (14) open towards the outside of the radial direction,and an insulating coating film (15) is formed on the wall surface of the annular recessed portion (14). In addition, a plurality of excitation coils (8) are directly wound around the annular recessedportion (14).

Description

technical field [0001] The present invention relates to an excitation device in which an excitation coil is wound around an inner pole member of an excitation core, and a non-excitation service brake provided with the excitation device. Background technique [0002] Electromagnetic coupling devices are divided into electromagnetic clutches and electromagnetic brakes. The electromagnetic clutch is arranged on the power transmission path between the drive side member and the driven side member, and transmits power or blocks power transmission by energizing or disconnecting the excitation coil of the excitation device. The electromagnetic brake stops the power transmission of the driving side member, and then energizes or disconnects the excitation coil of the excitation device, thereby braking the inertial rotation of the driven side member and keeping the driven side member stationary state. [0003] For example, as disclosed in Japanese Patent Application Publication No. 6...
