I used my Rpi Pico mircoPython program to enter numerous responsibility cycle 1kHz PWM sign to your BLDC motor and located the subsequent final results.
A immediate element causes a rotation (or simply a period shift inside the rotating 3phase domain) then why is just not there one particular PID loop which optimises with the per cent with the output energy that goes to Iq? Something like looking to get Iq/(Id+Iq) to generally be as near one as feasible.
m x 769rpm = 1930W mechanical output electricity, but input power is 6035W. You claim that performance is 81% at 140A so this does not compute. What have been the measurements you made use of to obtain the eighty one% effectiveness? $endgroup$
In this article is another seven page paper with dialogue of electrical braking BLDC. It also says mechanical brakes are essential for static braking.
What I am trying to say is this suggests very little about the worth of $I_q$, it may be nearly anything. Or in other words; only earning $I_d$ drop by zero doesn't give you a issue Remedy, it will give you a line.

Customizable Ability: We provide a wide array of gearboxes, brakes, and encoders to develop the perfect motor Resolution for the precise requirements
FOC will not must evaluate period voltage/back again-emf in any way. In its easiest type, you're just figuring out exactly where the rotor magnets are relative into the stator (the all critical electrical angle) and then location 3 voltage levels which will optimally deliver torque at that angle.

Anytime there was a need modify or perhaps a load alter the controllers response would bring about a stage shift from the 12v DC motor desired angle and so compromise the power of the process to create torque correctly. By applying independent controllers for Id and Iq, their precise contributors to the general system reaction is often controlled. Iq is free to alter centered upon a need from an outer velocity loop when Id is controlled to rotate the vector due to any doable rotation due to acceleration or velocity.
That is a robot ideal? Can you just method it to turn so it sits ninety degrees to your slope Every time it detects it's got come to a cease on a slope? $endgroup$
It is achievable to changeover between continual Procedure and stepper operation and to use DC towards the windings to offer some holding torque.
How can a DC brushed motor produce a rotating magnetic discipline? It employs a mechanical commutator. In a brushless motor you do not have that, instead you represent the sphere by two Custom DC motor manufacturer vectors- Iq and Id. In essence Iq is identical controller you experienced while in the DC brushed, Id is the best way to set the angle.
