BLDC controller have 3 speeds provided, by default 2 speed is selected, when i select the 1 speed, 2 speed or 3 speed there will be no kind of change is made by the controller on BLDC motor, i am not getting which type of problem is it. can you guys help me to sort out this problem.
Keep in mind that BLDC speed control is a frequency problem, not a current problem. What is the model of the speed controller?
first of all thanks for your interest
yeah you are right its not the current problem. its a frequency problem generated by the stm32 in form of PWM. but problem is that when i change the speed of motor its will not change and remain constantly running at the same speed.
model number of BLDC controller is not known, its 60 Volt and 32 ampere BLDC Controller.
In that case, it sounds like a problem at the program level or with the switch input. Do you have access to a schematic and/or the firmware?
actually i have two controller and both got same problem, I make many changes in their circuitry change of capacitors and transistors suddenly one of them start working properly.
but 2nd one will remain in fault condition.
it means there is no kind of program level.
there is possibility of problem in switch input.
so let me to troubleshoot it.
if you have any knowledge how to test it kindly share it with me.
