$begingroup$ If Keeping torque is needed, It's going to be necessary to use both a stepper or a brake. Efficiency is just not only critical for factors of energy usage, even though; a far more effective motor could be smaller and lighter than a person which requirements in order to dissipate more electric power as heat than it is going to ever be referred to as on to provide mechanically.

A direct element leads to a rotation (or simply a section change within the rotating 3phase area) then why just isn't there a single PID loop which optimises with the % on the output ability that goes to Iq? One thing like endeavoring to get Iq/(Id+Iq) to be as close to one as is possible.

Commonly, having said that, you commutate a brushless DC motor optimally, much like the mechanical brushes would attempt to do. What this means is retaining the magnetic subject at 90° from The present posture while in the path of ideal rotation.

- If you discover that you've got loads of Room involving the motor and battery and that the ESC prospects usually are not long enough to reach, extending the motor wires is the greater Answer.

Designed to Last: Rugged design and very low inertia hold these motors running robust, even in harsh environments.

You might have answered the two of my inquiries. To be a matter of point There exists 2 options in VESC - "Max. motor existing" was set to 140A, however I've had to Opt for an "Complete Highest Present-day" of 180A to stay away from less than-voltage mistakes. $endgroup$

Several days ago, I have study a very attention-grabbing discussion on this forum about the difference between brushless and stepper motors. I think what I need really should be the holding torque like it transpires for stepepr motors.

You may be able to modify the computer software to use a small DC voltage to provide holding torque. You should ascertain just micro motor how much DC latest is often used with no overheating the motor.

We simply cannot comprehensive your request because of a technological trouble. You could return for the previous site or

$begingroup$ I have been considering code to do FOC and seen that two PID controllers are often employed for torque control -- one that keeps Id close to zero and One more that maximises Iq.

Instance: When using a GR motor with nominal 12 V in a provide voltage of 24 V, the no-load velocity doubles and your complete motor attribute curve shifts parallel appropriately. This ends in a substantially increased continual output electricity in the motor.

You'll be able to sit on a slope all day with out draining battery ability. I do typically wish there have been a lot more ready designed "optical mice-like" optic circulation type sensors which will just stare at the ground nevertheless to assist with encoders and IMUs. $endgroup$

$begingroup$ The connection in between the torque consistent and also the pace frequent (Kv) in the report is correct. Ia is alleged to be armature present, not battery current. Was the armature existing a hundred and forty Amps?

That has a brushless motor you may have other options. I lately did a task where by the customer needed very correct motor pace. In that situation I communtated small worm gear motor the windings at precisely the desired speed derived from a crystal oscillator.
