Fast, powerful, quiet, small and secure motor

Hello,

It is long time can’t figure out with suitable device, I need your help

I use 8 servo motors in my Arduino Uno with Adafruit Servo Shield project Power HD High-Speed Digital Micro Servo DSM44 and FEETECH Mini Servo FT1117M which is quite cheap and useful for my prototype assembly. DSM44 works fine, because it is small, fast and quite powerful, with taking into account that my mechanics acceleration requires a small mass, but there is two problems with DSM44, maybe because I have not permanent, but intensive load on motors, I’m really not sure about reason, (I’ve described and discussed problem here DSM44 servo failure) and also servo is loud. So, I’m looking for suitable device which will cover most of specifics required for my device:

  1. Speed: No less 0.07 sec/60° with 6V

  2. Power: Torque no less 1.5 kg cm with 6V

  3. It does not requires get feedback, as if I use smart servo, but must be digital, because degree position should operate in short ranges with high speed, so quick response, fast acceleration and accuracy is important

  4. Small size: from 20x9x26 or less to 35x12x30 plus/minus 1-5mm max

  5. Must be a quite, silent as much it is possible

  6. Must be secure for not constant, but intense work processing of serial events

  7. Control method uses Arduino Uno and Adafruit Servo Shield 6V 8A power supply, sanding of PWM degree value via serial port from C# desktop application , so controller sketch contains only receiver conditional function per each unit

Once, I’ve tried stepper like this one Stepper Motor: Bipolar, 200 Steps/Rev, 20×30mm, 3.9V, 0.6 A/Phase by size with A4988 driver, a bit much powerful then this particular motor, but finally I decided that the stepper is not quite suitable device for my project by number of reasons.

So, here is a options that I try to understand and figure out what could be the best choice in my case:

  1. I’m not quite sure about Brush Servo Motor and Brushless difference with my requirements, maybe I should use Brushless motors

  2. I’m thinking about ClearPath Servo Motor in terms of silence, however, the control method as available size of the motors is not entirely obvious to me yet

  3. And as variant controlling of DC motors with some kind of shield for Arduino Uno controller, I’m not quite sure about device and assembly in this case as well as on controlling multiple DC motors with PWM from Arduino with some suitable board like this Dual H-Bridge Motor Driver L298N, but for 8 motors and I guess must be DC motor position control system

Maybe I have to use some professional device, if it is possible to find something not very expensive

Any advice, guide or example would be helpful

Hi,

Without knowing what you want to achieve, it is pretty much impossible to advise if you should use a servo, a stepper, a DC brushed or brush-less motor.

Here is a guide to help you with the basics of different motor’s type.

Note that each motor will need a different kind of Motor Controller.
