New description: [New technical field] This creation is a momentum dynamic meter, especially a principle that uses the law of conservation of angular momentum and fixes a rotary power device through a fixture on a fixed seat, for example, to be tested. a motor, and a torque measuring device for measuring the torque reacted by the motor to be tested after being loaded by a torque meter. [Prior Art] The conventional motor torque and speed method is the traditionally used loading method, that is, using the brake device or the feeding motor as the load to control the braking force at the load end, in order to achieve the required speed and torque. If the motor is the force 'the load end motor is the reaction force, the braking force (resistance) is large, the motor to be tested will have the corresponding torque output, and the motor and the load to be tested can be connected to the group torque sensor ( Torque meter) to observe the relationship between the torque and the speed of the motor to be tested during the loading process. Please refer to the figure-picture. Figure 1 shows the state diagram of the conventional motor dynamometer. The motor power is 510. (Motor output torque detecting device) is mainly produced by a controllable torque or a controllable speed. The load output of the control, a torque meter 12 is connected to the shaft of the load motor 与 and the load unit 透过 through a reclosing device 连 (coupling device) for measuring the motor 13 to be tested. _ speed output torque. The conventional motor output torque detecting device or motor power meter has the following disadvantages: (1) the motor 13 is not, the peach turning motor 13, the torque -12, and the fresh TG 11 three-axis strictness requirements need to be finely adjusted; 2.) The test process cannot quickly replace the sample of the motor 13 to be tested. Therefore, the secret inspection or the full inspection process needs to be slow, so it takes a long time; (1) (4) Rotary type used in the motor power meter The torque 4 I2 mesh and the motor 1 to be tested 1; 3 rotate synchronously, so that the torque meter 12 has a rotation speed or the motor 13 cannot be continuously rotated. Because the conventional motor dynamometer j has the shortcomings of the above-mentioned installation measurement and measurement time, there is still no effective method or device that can perform the mass reading and secret inspection or sewing of the motor product. This new motor product is a small motor. It is difficult to meet the requirements of the high fresh product f specification, for example, to provide the process capability level value of the starting and maximum torque output of a batch of motors to determine the uniformity of the output dynamic performance of the batch of motors. [New content] A kind of momentum dynamometer uses the principle of angular ambiguity to quickly combine a rotating power device such as a motor to be tested with a fixture, and torque measurement of the motor to be tested is performed by a torque meter. For the above purposes, the present invention is to provide a momentum dynamometer, f for measuring the rotational force of a rotating power unit such as a motor to be tested, such as a Li seat, a torque meter, a connecting arm, and a load device. The system includes a body and a measuring end; the system is fixed on the fixed seat. The connecting arm includes: a fixing hole, and a jig; the fixing hole is coupled with the measuring end, and the jig is used for combining the power output end of the motor to be tested, and The principle that the power axis of the motor to be tested is parallel and the law of the momentum of the paste is controlled by the torque meter is used to measure the torque of the horse. [Embodiment] In order to more clearly describe the dynamic force meter proposed in the present invention, the following will be described in detail with reference to the drawings. Please refer to Figure 2 and Figure 3 for the perspective view of the momentum meter and the ship's display. Among them, the present invention is to provide a momentum dynamometer 2, which uses the principle of "angular momentum to keep the mosquito" to perform a torsion force measurement of a rotary power device such as the motor 3 to be tested, which includes a fixed seat 2 - torque meter 22. A connecting arm 23, a load device 24, a control unit 25, and a power input unit %. The torque. The tenth 22 series includes a body 221 and a measuring end 222. The motor 3 to be tested includes a motor body 3 and a power output terminal %. The fixing base 21 has a platform 211, and a fixing frame 212 is vertically extended on the platform 211. The fixing frame 212 has a joint portion 2121 to provide the body 221 of the torque meter 22 for fixing the torsion meter. 22 is securely attached to the holder 212 to which the platform 211 extends. In the present embodiment, the torque meter is a jihsense Type μ cap.l Nm torque meter, which is used to measure the preset load applied by the motor 3 to be tested via the load device 24. The connecting arm 23 includes a fixing hole 231 and a jig 232. The fixing hole 231 provided at one end of the connecting arm 23 is coupled to the measuring end 222 of the torque meter 22. The jig 232 is substantially at the other end of the connecting arm 23 and conforms to the external shape of the motor 3 to be tested, so that the motor main body 31 of the motor 3 to be tested is fixed at an external speed and accurately fixed in the jig 232. The time for replacing the sample of the motor 3 to be tested is saved; of course, when the two ends of the connecting arm 23 are respectively combined with the measuring end 222 of the torque meter 22 and the motor body of the horse to be tested 3, In the present momentum momentum meter 2, the central axis A of the measuring end 222 of the torque meter 22 is parallel to the central axis b of the power output end 32 of the motor 3 to be tested to facilitate the use of the angular momentum by the torque meter 22 The principle of the conservation law measures the inertia generated by the motor 3 to be tested under load. In addition, the load device 24 can be indirectly provided with a preset load on the power output end 32 of the motor 3 to be tested. In the present embodiment, the load device 24 is a wind tunnel device, and a fan 4 is disposed on the power output end 32 of the motor 3 to be tested, corresponding to the load device 24, through the load device 24 (wind tunnel) The generated wind resistance provides the preset resistance of the fan 4, so that there is no need to directly contact the power output end, and the assembly time is saved. That is, how much the wind resistance of the fan 4 applied to the power output terminal 32 by the load device 24 (wind tunnel) is connected to the torque corresponding to the reverse torque output of the connecting arm 23 on the motor 3 to be tested. How much is there, and the torsion meter 22 connected to the other end of the f 23 is used to measure the relationship between the torque and the rotational speed. The torque meter 22 is electrically connected to the control unit, and the control unit 25 can be a computer, an analyzer, or an electric signal acquisition module 1 (four) Μ 25 the torque meter 22 measures the to-be Z up to 3 Various data (such as load, speed, torque, angular velocity, etc.) are further analyzed by professional software. The power source is connected to the motor 3 in the early morning 26, and the drive power is supplied to the power of the motor 3 to be tested (4) & rotation, thereby driving the fan 4 to rotate. When the power input unit 26 drives the motor 3 to rotate the fan 4 located on the power wheel outlet 32, the load device 24 (wind tunnel) applies a wind resistance to the rotating fan 4 to make the fan 4 Withstand the resistance from the 贞«定24-定度, at this time, due to the angular momentum training law, the motor body of the motor 3 will have the direction of rotation of the fan 4, that is, the power output end% The angular momentum of the opposite direction of the rotation is further driven by the fixture 232 fixed thereto to be coupled to the measuring end 222 of the torque meter 22 through the connecting arm 23, and the motor 3 to be tested is transmitted through the control unit 25. The generated inertia is added to record to test whether the motor 3 to be tested reaches the expected torque standard. Without further elaboration, the so-called conservation law of angular momentum (c〇nservati〇n 〇f Angular Momentum) means that the angular momentum of the system remains unchanged when the external moment of the system is zero. When the moment is zero, the angular momentum is not known. Over time, for a system that is not affected by external forces, its angular momentum L = EIW = 0. In the present case, the power output end 32 of the motor 3 to be tested is rotated at a Wi angular velocity (the moment of inertia: 1 〇, the motor body 31 will drive the connecting arm 23 to rotate at an angular velocity of W2 (moment of inertia: 12) Angular momentum L = EIW = Ii W1 + I2W2 =0 (τ = torque, W = = angular velocity, 1 = moment of inertia) II Wl = -l2W2 Consider the change in unit time

Therefore, the load device 24, that is, the wind tunnel is applied with a predetermined load on the fan*, so that the torque meter 22 fixed on the connecting arm 23 also receives the bribe of the motor to be tested 4 12 Chengsheng reverse torque moment gate, further using the torque meter 22 to transmit the detected data to the control unit 25, and the control unit 25 performs data on the inertia load of the motor 3 to be tested (rotation speed, torque torque) , angular velocity, moment of inertia.···) Integrate the comparison analysis, accurately test and analyze the moment of inertia of the motor 3 to be tested and the angular acceleration of the motor 3 to be tested. In summary, the present momentum momentum meter 2 improves all the disadvantages of the conventional motor power meter 1, not only enables the motor 3 to be tested to be quickly coupled through the fixture 232 on the connecting arm 23; The relationship between the connecting arm 23 and the central axis A of the torque meter 22 and the axis B of the motor 3 to be tested fixed on the jig 232 are prevented from being parallel to each other by using the motor dynamometer i as shown in FIG. The mechanism 14 respectively connects the motor 3 to be tested, the torque meter 12 and the load carrying unit 11 with high concentricity; the T type saves the time for the test assembly of the axle quantity dynamometer 2; The limitation of the rotational speed of the torque meter 22 itself allows the motor 3 to be tested to be detected by the Momentum Dynamic Juice 2 of the present invention while maintaining high-speed rotation, thereby achieving a more convenient, economical, and more accurate test platform.
