The birth of the dynamometer
Since the industry has demand, the market will have a corresponding product. Test equipment manufacturers found that most of the motor tests were tested under load, and with the development of embedded technology, the communication and control of sensors and instruments became more and more convenient, so they tested instruments, sensors, The mechanical loading system did a fusion - the test system in the initial sense, the dynamometer, was born.
The construction of the dynamometer is very simple. It consists of a cabinet and a test bench. The test bench is often called a dynamometer. It is generally a model in which the torque and speed sensors are integrated into one. The test bench includes a mounting base, a torque speed sensor, and a mechanical load (brake); the cabinet includes an electrical parameter tester, a motor tester, a dynamometer controller, a power supply, etc., and the functions of the components are as follows:
Mounting base - for mounting and fixing the motor to be tested;
Torque speed sensor - used for the speed and torque collection of the motor under test;
Mechanical load - generally use brakes, also use the motor, used to provide the reverse torque of the motor under test, absorb the power of the motor under test, achieve the "loading" of the motor under test, simulate the actual operation of the motor condition;
Electrical parameter tester - used for collecting and displaying electrical parameters such as voltage, current and electric power of the tested motor;
Motor tester - used to collect the output signal of the torque speed sensor and digitally display the speed, torque and mechanical power of the motor under test;
Dynamometer controller - used to control the mechanical load output different torque;
