It consists of a suspended AC motor, a tension and pressure sensor force measuring device, a speed sensor, a mounting base, and a flange connected to the power machinery, an ACS800 series AC variable frequency speed control system that can operate in four quadrants, and an AC power dynamometer measurement and control instrument.
The electric dynamometer adopts AC frequency conversion feedback loading, and the loaded energy measures the voltage, current, power, and speed of the motor through the AC load generator
It is mainly used in large machine tools, wind power generation equipment, electric ships, and motor manufacturers, and can provide high-precision motor parameter measurement and calculation software, supporting special computer hardware equipment and other services. Dynamometers are widely used in machinery manufacturing, wind power generation equipment, electric vehicles, industrial control systems, etc.
The electric dynamometer adopts AC frequency conversion feedback loading, and the loading energy is fed back to the power grid through the AC load generator; Torque and speed are directly measured by the torque sensor; Current, voltage, frequency, power factor, and other electrical parameters are measured by the tester; Determine the power of the equipment through torque and speed conversion. Considering that the measured motor may have different rotational speeds, the motor used as a pair must be a motor with smooth speed regulation. Electric dynamometer includes DC electric dynamometer and AC electric dynamometer. At present, an AC electric dynamometer is widely used.
Different working principles:
The electric dynamometer is tested using the principle of electromagnetic induction, while the eddy current dynamometer is tested using the principle of magnetic induction.
Different application scope:
The electric dynamometer is mainly used to test the output power and speed and other parameters of internal combustion engines, automobile engines, wind generators, hydraulic generators, etc., while the eddy current dynamometer is mainly used to test the conductivity, magnetism of metal materials, and defects of metal parts.
Different test precision:
Eddy current dynamometer usually has higher test precision and resolution than electric dynamometer, because it can detect very small defects and changes.
Different test speeds:
The electric dynamometer usually has a faster test speed than the eddy current dynamometer, because it can complete the test in a shorter time and get the test results quickly.
Different equipment costs:
Eddy current dynamometer is usually more expensive than electric dynamometer because it requires more precise test equipment and a higher technical level to operate and maintain.
