The reason why this magnetic particle dynamometer is so popular is here! !!
Magnetic powder dynamometer is a brake dynamometer (torque machine) designed and manufactured according to the principle of magnetic powder torque technology. It is a torque machine that applies torque load to the motor under test and absorbs its power. Converter. Both the speed sensor and torque sensor are installed on the dynamometer. The speed and torque of the motor under test are converted into pulse signals and analog signals by the dynamometer and sent to the dynamometer controller for display. When the dynamometer is rotating, all the power output by the motor is absorbed by the magnetic powder dynamometer and converted into thermal energy, which is dissipated by means of a radiator and peripheral cooling fans or water cooling.
When working, the controller provides the excitation current to the magnetic powder dynamometer. When the internal coil of the magnetic powder dynamometer is energized, a magnetic field is generated, so that the internal magnetic powder is arranged in a magnetic chain according to the magnetic lines of force. Resistance. This force is the load torque. The magnitude of this torque is only related to the current applied by the controller to the dynamometer coil, and has nothing to do with the speed at which the test motor drags the dynamometer to rotate.
Magnetic particle dynamometer and its testing system are composed of magnetic particle dynamometer, dynamometer controller, electrical parameter measuring instrument and acquisition device, test power supply, operating table and electrical cabinet, dynamometer stand / tooling fixture and accessories, computer and It is composed of special testing software, which can arbitrarily change the load of the motor under test, and directly measure the input voltage, current, power and output torque, speed, output power and efficiency of the motor under no-load, load, and stalled conditions.
Magnetic particle dynamometer is suitable for testing motors with low to medium speed or medium to high torque range. Like hysteresis dynamometers, magnetic powder dynamometers provide maximum torque at zero speed. Both it and eddy current dynamometer adopt water cooling method, and the maximum test power can reach 14KW.
