Problems solved by technology

[0002] Previous motors, no matter AC or DC control servo motors, have no anti-electromagnetic interference structure and function
Especially when it is applied to the banknote counter or banknote detector, due to external electromagnetic interference, the banknote counter or banknote detector sometimes fails
Although it has attracted the attention of the banknote counter manufacturers and has also improved the banknote counter and strengthened the shielding, but due to the incomplete shielding, the problem of low banknote counting accuracy still occurs

Embodiment Construction

[0011] The embodiments are further described below in conjunction with the accompanying drawings.

[0012] refer to figure 1 , 1—front cover, 2—shielding back cover, 3—shielding outer cover, 4—motor casing, 5—shielding magnetic tile sleeve, 6—magnetic tile, 7—motor back cover, 8—bearing, 9—control board, 10—motor rotor, 11—motor shaft. As shown in the figure, in order to strengthen the shielding and improve the anti-interference performance of banknote counters and other motors, the following examples are used to illustrate:

[0013] The first embodiment: when the motor has a casing 4, a stator, a back cover 7, a bearing 8, a control panel 9, a rotor 10 and a motor shaft 11, at this moment, the reinforced shielding is to wrap a layer outside the motor casing 4 To the multi-layer shielding outer cover 3, and install the whole motor core in the large housing composed of the front cover 1 and the shielding back cover 2, so that the layers of shielding prevent the external elect...

Abstract

The invention relates to the field of motor manufacturing, in particular to an anti-electromagnetic interference control servo-actuator. The servo-actuator is characterized in that on the basis of the prior control servo motor structure, the outside of a servo-actuator shell (4) is coated with one or a plurality of outer shielding covers (3); the whole machine core is arranged inside a large shell consisting of a front cover (1) and a rear shielding cover (2); the front cover (1) is made of metal and forms a shielding layer with the rear shielding cover (2); and a stator is formed by assembling a shielding magnetic shoe sleeve (5) and a magnetic shoe (6). The anti-electromagnetic interference control servo motor strengthens shielding on the whole and further improves the capacity for controlling anti-electromagnetic interference of the servo-actuator, thereby putting an end to failure phenomenon of a currency counting machine or a currency detector and further improving the currency counting precision of the currency counting machine.

Description

technical field [0001] The invention relates to the field of motor manufacturing, in particular to an anti-electromagnetic interference control servo motor. Background technique [0002] Previous motors, no matter AC or DC control servo motors, have no anti-electromagnetic interference structure and function. Especially when it is applied to a banknote counter or a banknote detector, due to external electromagnetic interference, the banknote counter or banknote detector sometimes fails. Though, cause the attention of money counting machine manufacturer, also money counting machine is improved, strengthened shielding, but because shielding is not thorough, the problem that money counting precision is not high still occurs. Contents of the invention [0003] The object of the present invention is to provide an anti-electromagnetic interference control servo motor for the above defects. [0004] The technical scheme of the present invention is an anti-electromagnetic interf...
