Hey Guys,
i'm from germany and i try to do a small kind of tractor with electrical drive instead of diesel.
So i bought a Golden Motor HPM-10KW motor 48V and use a sevcon gen4 size6 do drive it. In future i want to use two motors with two controllers.
Motor uses a hall-sensor.
Actual i try get the combination running. status quo is that the motor is running, also has power, but not at the beginning of turning. so i have to press full throttle to start, then have imideately remove to minimal throttle so that the vehicle is not going to speed up to maximum speed.
I was trying a few hours playing with the kp/ki values for starting and for normal running. It is like searching a needle in a haystack.
So hopefully someone is using the same combination and has a good behavior for start running and he can share the parameters with me, so i may have a better position to start tuning the parameters for me.
i have not a testbench.. only a flat area and a hill where i want the motor starting from zero without any issue.
also i would be realy thankful if someone can give me a good advice how to tune the parameters in a quick and direkt way.
Maybe i should add the information, that i use the sevcon without a hardware throttle. it is all over CAN. So i want to use a remote, also sitting on the vehicle and also in future a kind of autonomus driving.
I send the target rpm. and this is basically working.
I want to thank you for your help. And sorry for my bad english. I hope everyone understands what i want to tell you
best regards, franz
