Hello Have you ever attempted to control a 3-phase, 12-pole Brushless DC motor using PWM with an Arduino? If so, were the movements smoother compared to using a 1-pole motor? Additionally, which motor driver did you utilize? , Do you have any recommendations for motor drivers available in the Multi…

[image] hori1919: Brushless DC motor using PWM I cannot find hardware support for three waves of 120° phase shift on Arduinos. It also is required to switch the pulse polarity with every pulse. IMO it's a good idea to use a BLDC driver module. For software control 3 half H-bridges are requir…

What size motor and what are the power requirements for it.

Hi, @hori1919 Welcome to the forum. [image] How to get the best out of this forum IDE 1.x See also FAQ - Arduino Forum for general rules on forum behaviour and etiquette. Hello, Welcome to the Arduino Forum. This guide explains how to get the best out of this forum. P…

The small motors are typically driven with a variable frequency 3ph waveform - typically using a motor controller(ESC) for RC aircraft/cars which generates the waveforms and has a simple PWM control input to represent speed and a DC supply for the controller . This is the easiest method . Info …

Hello, Thank you all for your replies and time. In the attachment, you can find the model of the 3-pole DC motor. The idea is to develop a head for a Camera Crane that can control pan and tilt. I've been thinking about how using a 3-pole motor would work for this project. I have never seen a Crane…

[image] hori1919: I have never seen a Crane jib with a 3-pole DC motor before. Probably with good reason !! Servos are the usual solution , as you will need to have position feedback

Hi, @hori1919 [image] hori1919: The idea is to develop a head for a Camera Crane that can control pan and tilt. How do you aim to do that? Those motors will not like turning at very low speed. [image] hammy: Probably with good reason !! Servos are the usual solution , as you will need…

Hi, I'm sorry for the delay, but I haven't been able to be active I expect to achieve a maximum speed of approximately 50 degrees per second and will use a reduction ratio of approximately 1:8. It's worth noting that the motor's RPM at the shaft is 68 when operating at nominal torque. I believe t…

[micromotors] In reference to point 5 (PWM): What do VIH and VIL mean? For example, if I apply a PWM voltage of nearly 10%, will the DC motor begin rotating?

Hi, @hori1919
Welcome to the forum.

Can you please post a link to the specs/data of the motor?

What is your project?
What is the application?

Thanks.. Tom..
