$begingroup$ If holding torque is necessary, It'll be important to use either a stepper or a brake. Performance isn't really only important for factors of energy utilization, nevertheless; a more productive motor is often smaller and lighter than a single which desires to have the ability to dissipate much more energy as heat than it'll ever be referred to as on to supply mechanically.
What would come about if aspects of Iq was utilised given that the Id need. For starters it would want to become elements of Vq to impact Vd For the reason that output in the PI(D) is voltage not current. What would materialize if we had a person PI controller that normally takes within an Iq desire and generates a Vq based upon the existing Iq. From this deliver Vd dependent upon say ... $Vd = frac Vq Vd+Vq $ akin to the first question. We would have a response which varies the section partnership from the utilized voltage dependent on the quadrature existing need.
m x 769rpm = 1930W mechanical output ability, but enter electric power is 6035W. You say that efficiency is eighty one% at 140A so this does not compute. What were being the measurements you utilized to find the 81% effectiveness? $endgroup$
Several of the energy will probably be absorbed with the mechanical method. You might be able to estimate that by observing just how much the pushed process coasts when it is shut off without braking.
Each and every with the 6 traces was pushed seperately by a microcontroller. It is actually up to your firmware to under no circumstances activate the substantial and reduced side motorists of pair concurrently. $endgroup$
This wastes plenty of Strength, since it generates no torque Except if the load tries to convert out of place, nevertheless it does avoid the need to have for almost any opinions mechanism.

However, with some extravagant footwork within the energizing on the stepper motor coils, modern stepper motors with suited controllers can often give rotation in partial ways, often called micro-stepping. TL;DR: Stepper motors are (generally) a subset of your Brushless Motor loved ones.
- Usually do not reverse the sales opportunities with the battery into the ESC under any circumstances. This could not reverse the motor and it'll demolish the ESC.
Despite these distinctions, a stepper might be operated just like a BLDC, or maybe a BLDC similar to a stepper. However, presented the conflicting style and design intentions, The end result is probably going being below ideal.
- Be sure the throttle array is calibrated effectively In the event your ESC demands it. Verify the Recommendations custom DC gear motor for particulars on the exact ESC.
In the event the motor features a separate field winding rather than a permanent magnet, you have got to energise that winding from an external DC resource, e.g. a battery.
Now on your question a couple of brushless DC motor. The one change would be that the windings usually are not mechanically switched in and out based on the rotation angle in the motor. If you switch them optimally as the brush program within a brushed DC motor is intended to accomplish, Then you definately get a similar thing.
If That is suitable (that knowing this period offset at any point in time will be ample to optimally ascertain what voltage to placed on what windings) then why is just not there a person PID loop which optimises with the p.c of your output electric power that goes to Iq? A little something like endeavoring to get Iq/(Id+Iq) small worm gear motor to be as near 1 as you possibly can.
