New type of description: [New technical field] The present invention relates to a motor, and more particularly to a type of stopping device mounted on a rotating shaft of a motor, which can be used to stop the rotating shaft from stopping. Functional motor. [Prior Art] The motor is a commonly used driver, and some motors are mounted on a rotating shaft end edge - a transmission member such as a gear ' to indirectly drive a load such as an axle or a speed reduction mechanism, and some motors are in the The shaft end is mounted with a load such as an impeller to directly drive the load to rotate. When the load is stopped, the motor must be stopped. However, because the shaft is still used to rotate: until the deceleration stops, and the brake cannot be stopped immediately, the motor must be installed. Or indirectly, the shaft is actuated to ensure that it does not rotate in the stopped state. At present, a variety of motors equipped with brake devices have appeared on the market, and the present invention provides a motor with a structurally innovative function for consumers to choose to use 0 [new content] * Therefore, the purpose of the present invention is That is, it is to provide a motor that is innovative in construction and uses the function of the long-term function. : The new motor with a stop function includes a motor body and a brake device. The motor body includes a pivot shaft. The brake device f includes a brake piece fixedly mounted to the rotating shaft, and at least one electromagnetic unit corresponding to the wearing piece in the vicinity of the brake piece, the electromagnetic unit having two 3 M423403 electromagnets opposite to each other on the side of the brake piece When the electromagnet is not energized, the brake shoe is not subjected to magnetic force and rotates with the rotating shaft, and when the electromagnet is energized, the brake shoe will be subjected to magnetic force to stop rotating while the rotating shaft is also immediately The brakes stopped. The utility model has the advantages that the design of the braking device can make the electromagnets of the electromagnetic unit face each other on the two sides of the braking piece, and select and control the braking piece by energization or not, so that the braking device does not contact wear when braking. , can have a long service life. The above and other technical contents, features and effects of the present invention will be apparent from the following detailed description of the preferred embodiments. Referring to Figure 1, a preferred embodiment of the present motor can be mounted in a vehicle, appliance or various mechanical equipment and includes: a motor body, and a brake device 2. The motor body i includes a casing u, and a rotating shaft 12 that protrudes from the side of the casing 11 and can be rotated (of course, the motor body 1 further includes a casing U installed therein, and In order to drive the rotation shaft 12, the stator and other structures, but the general technology is not the focus of this new type, so here: further details. In addition, the two end edges of the transfer can directly or indirectly connect p loads 3, such as gears , the axle, the speed reduction mechanism, the impeller or the fan, etc., are used to drive the power out to the load 3 to drive the load 3 to rotate. The braking device 2 includes a brake shoe 21 fixedly mounted to the rotating shaft 12 and rotating therewith, a fixed installation unit 22, two 4 corresponding to the electromagnetic unit 23 in the vicinity of the brake shoe 21, and a control unit 24 for controlling the electromagnetic unit 23. The brake shoe 21 is a circular piece It is made of a magnetic conductive material such as iron, Shihashi Steel, etc. The anti-shocking unit 22 is made of a carbon fiber reinforced resin (CFRp), or a non-magnetic material or/and a non-conductive material such as Wei Chengshi·. Made and has two corresponding positions on the periphery of the brake shoe 21 The mounting seat 22 can of course also be a (four) surrounding the periphery of the rotating shaft 12 (as long as it can be used for fixing the electromagnetic unit 23), it is not limited to the embodiment. Each of the electromagnetic units 23 has two electromagnets 23 opposite to each other on the sides of the brake pads 2, and a gap 232 between the electromagnets 231 and the brake pads 21. The magnetic force can be generated and the friction does not occur. After the energization of the embodiment, the electromagnets 231 located on both sides of the brake shoe 21 have opposite polarities, and of course, the same polarity can be implemented as long as the brake shoe 21 can be produced. The magnetic force can be used. Of course, the number of the electromagnetic unit 23 can be increased or decreased. For example, only one is provided, and the control unit 24 is electrically connected to the electromagnetic unit 23 and a power source (not shown). For controlling the energization of the electromagnetic unit 23, but the circuit control design is not the focus of the present invention, and the control unit 24 can also omit the arrangement, and the electromagnetic unit 23 is electrically connected to the circuit system of the motor body. When the motor body 丨 is turned off, the electromagnet 231 is energized, so it will not be described in detail here. When the motor body 1 is activated, the electromagnet 23 1 is not energized and does not generate a magnetic field. The brake shoe 21 is not subjected to a magnetic force and rotates with the rotation shaft U. [The rotation shaft 12 drives the load 3 ^ When the motor body 1 M423403 is stopped, the electromagnet 231 is energized, and the magnetic field 21 is generated by the magnetic force. Stop turning, 吏^, the car stops, and does not drive the load 3. The sleeve 12 is also braked to produce a single value 1: It is mentioned that in order to avoid the situation of rapid braking, the control, rain = on, Alternatively, the electromagnet 231 may be intermittently applied to the electromagnet 231 to generate an intermittent magnetic force, and the intermittent action of the plurality of times may be extended to extend the braking stroke to achieve the effect of the connection. ▲ In summary, the motor of the present invention uses the electromagnetic brake device of the brake device 2 to first mount the brake shoe 21 on the rotating shaft 12, and makes the electromagnets oppositely disposed on both sides of the brake shoe 21, using electromagnetic The iron 231 is energized to generate a magnetic field to stop the brake shoe 2, so that the rotation of the rotating shaft 12 can be ensured, and the electromagnet 231 and the brake shoe 21 do not contact the grinding device when the vehicle is braked, so that the service life can be prolonged, so the present invention is an innovative one. The structure is indeed able to achieve the purpose of this new type. However, the above description is only a preferred embodiment of the present invention, and the scope of the present invention cannot be limited thereto, that is, the simple equivalent change and modification made by the novel patent application scope and the novel description content, All remain within the scope of this new patent.
