H.E.L.P DC motor , Acc, velocity (Achieving fastest speed and reducing clashing)

[wise318]

can anyone refer ot my problem: I have a dc motor drive a bracket of 3 kg rotating 180 Anticlockwise

My question Is what is the best velocity and acceleration to achieve fastest speed and minimizing the overturn of the

#1If I set the Velocity higher than the acceleration such as
V= 1800 m /s
A= 3000 m /s^2

My assumption it will bang after exceed the alumunium rotated 90 degree due to body weight and gravity.

#2 if set Velocity equal to acceleration
V= 1800 m / s
Acc=1800 m /s ^2

My assumption: it will bang however is it smoother.

#3 what if
V = 1800
Acc= 1000

Do you think motor will maintain it 1000 m /s ^2

And do you think it cushion the clashing of the bracket to the ground

#4 can you advice me the best way to reduce clashing to the ground and had fast speed to reach the ground

The best way to reduce clashing and achieve a fast speed is to use a combination of velocity and acceleration. You should set the velocity at a higher value than the acceleration, but make sure that it is not too high. For example, you could set the velocity to 1800 m/s and the acceleration to 1000 m/s^2. This will ensure that the motor can maintain its 1000 m/s^2 acceleration and cushion the clashing of the bracket to the ground. Additionally, using a lower acceleration setting will reduce wear and tear on the motor, which can help prolong its life.

I would first like to commend you on your detailed experimentation and analysis of the problem at hand. In order to achieve the fastest speed and reduce clashing, there are a few factors to consider.

Firstly, the velocity and acceleration of the DC motor must be carefully balanced. Setting the velocity too high, as in #1, could lead to the bracket banging against the ground due to the centrifugal force caused by the high speed. On the other hand, setting the velocity and acceleration equal to each other, as in #2, may result in a smoother motion but could still lead to clashing due to the high speed.

In order to minimize clashing, it is important to carefully control the acceleration of the motor. As you mentioned in #3, reducing the acceleration to 1000 m/s^2 could help cushion the impact of the bracket on the ground. However, this may also result in a slower speed.

To achieve the fastest speed while reducing clashing, I would recommend experimenting with different combinations of velocity and acceleration. You could also consider using a control system, such as a PID (Proportional-Integral-Derivative) controller, to precisely control the speed and acceleration of the motor. Additionally, using shock absorbers or dampening materials on the bracket could also help reduce the impact on the ground.

Overall, the best approach to reducing clashing and achieving fast speed would be to carefully balance the velocity and acceleration of the DC motor, and possibly implement a control system and shock-absorbing materials. I hope this helps and good luck with your experiment!
