I am working with BLDC motor characteristic measurements. When we apply braking on the motor the motor kinetic energy turns into heat energy right? In this case, what can be used or what are the possibilities to cool that heat energy in test bench creation?
How can we know?
There are systems that recover the energy and store it back to battery, others will generate heat.
Some industrial systems use the generated energy to heat water.
What "performance" parameters do you want to measure?
Electrical, mechanical, audible noise, temperature rise, efficiency....

Thanks for the answering Klaus. Sorry, I thought i have mentioned the performance measurements type.
It is for electrical and mechanical parameters such as load current, torque, speed of the rotor etc.,
You told that there are some methods from which generated energy can be brought to heat water. Can you tell me if there are any devices or what methods can be made?
Torque is measured by seeing how well your motor powers a physical load. This can be done by having it spin a propeller in liquid or air As you speed up, or increase burden, you also increase current draw. Somewhere on the curve is a 'hilltop' which gives you maximum torque.
I would like to know what are the components or hardware (In creating the test set up or test bench) required to measure the BLDC motor electrical and mechanical performance for braking system applications in automotive?

Search on internet for " regenerative brake test rig- IRJET-archives". I was thinking of a flywheel setup and that seems to be the approach at that site.
what are the functional tests for BLDC motor for braking systems to be done? And what type of run time measurements are to be done? what are the measurement instruments needed to check the electrical performance tests of BLDC motor in braking systems applications?
