Hi guys
Just another brake question , as I try to finish my Gokart project
Is there anyone who know how to fix brake / keep motor position while stop ?
I am not talking about parking brake as it push 20.....50A to your motor (depend on settings) to hold on wheel
Regen brake is good when you drive fast, if slowing down ...and down ...and down efficiency of brake is going poor and finally will not stop till 0
what I need is to apply brake when is 1-2km/h (190-380erpm) for example) and hold on the wheel.
and keep position, but not push Ampers to motor if no need ...just let VESC to control motor position
If full brake can apply 50A to brake , while stop , is no need apply that much, but when you want to move wheel, it will start more and more Ampers 2....5.....10.....20...50A...depend how much you want to turn wheel
of course I use a sensored motor and FOC
or maybe another way to make a good brake? cant use mechanical brake because not have spae to install disc.
Thx in advance
In fact, another hw could be a solution. One of the job of that hw is to make the speed input of vesc is zero, when braked, and all the mosfets on the hw will short the phase legs of the motor.
