Embodiment Construction

[0072] Two preferred embodiments of the present invention are given below based on FIGS. 1 to 4, and described in detail, so as to better illustrate the structural and functional characteristics of the present invention, rather than limiting the scope of the present invention.

[0073] Refer to Figure 1, which shows the system structure of the present invention. As shown in the figure, the dynamometer of the present invention includes a DC power supply 1, which is connected in parallel to the load motor controller 21 and the motor under test via two power supply buses 12, 13 The controller 31 respectively connects the load motor 22 and the motor under test 32 with three-phase AC power supply lines 21a and 31a, and a torque sensor 23 is connected to the rotating shafts of the two motors 22, 32. The two motors 22 and 32 both have the function of four-quadrant operation. When the tested motor 32 is in forward (or reverse) electric operation, the energy flow is: power supply bus 12 (1...

Abstract

A monitoring system for dynamometer machine with the controlling and collecting data function is disclosed that includes direct-current supply, dynamometer device and system to be detected. They are connected with the CAN communication web, the motor to be detected is connected with the loading motor by the moment sensor, and the loading motor controller is connected with the detected motor controller by the direct current generating line to form a dynamometer circuit of direct current. The characteristics are those: it is equipped with the fan, water-cooling device, the switch plugs and the data capture ports of several parameters. The control and capture device which consist of project controlling machine to control, capture, and process the data, and the data is converted into files to be stored and displayed timely or printed report forms, and make the dynamometer easy to operate.

Description

Technical field [0001] The invention relates to a motor testing equipment, in particular to a device for monitoring the running process of the motor. Background technique [0002] The dynamometer is used to measure and measure the working performance of the motor. Generally, the AC grid grid-connected system is used, that is, during the operation of the load motor and the motor under test, the electric energy in the AC grid is partially It feeds back to the AC grid, but this AC grid grid-connected system has the following shortcomings: [0003] 1. Both the load motor controller and the motor controller under test must handle AC power in both directions, that is, when the motor is in electric operation, it must be able to obtain AC power from the grid and convert it into the AC power required by the motor. It is also necessary to be able to convert the electrical energy generated by the motor during power generation operation into alternating current that matches the power grid. A...
