Description

Technical Field

[0001] The present application relates to the technical field of motor testing equipment, and in particular to a calibration test bench for a 11Kw 20,000 rpm motor drag sensor. Background Art

[0002] The motor-to-drag test bench connects the driving motor to the motor under test, and provides a load to the motor under test by driving the motor to rotate. The operating status of the motor under load can be tested. The purpose of the motor-to-drag test bench is to establish a system that is close to the actual motor operating conditions. In addition to conventional motor performance tests, the test bench can also perform conventional motor life tests and accelerated life tests, and can analyze the causes and mechanisms of motor failures. The motor-to-drag test is a motor-to-drag test system designed for motor durability tests and performance tests. It can measure the motor's input voltage, current, output torque, speed, input and output power, efficiency and other performance parameters, and draw various performance curves.

[0003] After checking the public (announcement) number: CN219552609U, a motor towing test platform is disclosed. This technology discloses "including a platform body, on which a test motor assembly, a sensor test assembly and a motor body to be tested are arranged in sequence, and the sensor test assembly includes front and rear side panels, left and right side panels, a bottom plate and a top plate, and the front and rear side panels, left and right side panels, the bottom plate and the top plate form a sensor protective cover, and a test sensor is arranged inside the sensor protective cover. By setting the platform body, the test motor assembly, the sensor test assembly and the motor body to be tested and other technical solutions, the product can integrate the voltage, current, input power, torque, speed, output power and efficiency of the test motor body and the motor body to be tested, effectively saving the transportation time during motor testing, and when testing motors of different models, only the motor body to be tested needs to be replaced, which effectively ensures the motor testing efficiency and meets the use requirements of the motor manufacturing industry and other technical effects";

[0004] With respect to the above-mentioned related technologies, the inventors believe that most of the existing motor-drag sensors are integral and not convenient to assemble. Thus, if a certain structure is damaged, the entire motor-drag sensor can only be replaced. If the sensor can be assembled separately and the connectivity between the structures is good, a specific structure can be replaced if it is damaged. This will result in better use effect. In addition, for different motors, due to different installation dimensions, it is not convenient to install motors of different models, so there is room for improvement. Utility Model Content
