Discussion Overview

The discussion revolves around the power requirements and control methods for a high power DC motor, specifically focusing on the challenges of handling currents around 3 to 4 amps using electronic components. The scope includes practical electronics design and control circuitry.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • Ramone expresses a need for guidance on building an electronics controller for a high power DC motor, noting prior experience with small powered circuits using transistors.
  • Ramone questions the feasibility of using transistors as switches for the required current, suggesting a limitation in their current handling capacity.
  • One participant mentions the solution involves using high power transistors, but does not elaborate on the specifics or conditions of this approach.
  • A later reply indicates that the participant is a power electronics and motor driver designer, implying a level of expertise but does not provide further assistance to Ramone.

Areas of Agreement / Disagreement

The discussion does not reach a consensus, as Ramone's initial queries remain largely unanswered, and the mention of high power transistors does not clarify the specifics of their application or limitations.

Contextual Notes

There is a lack of detailed discussion regarding the specifications and limitations of high power transistors, as well as any assumptions about the circuit design or operational conditions that may affect performance.

Who May Find This Useful

Individuals interested in electronics design, particularly those working with high power DC motors or seeking to understand the challenges of current handling in electronic circuits.

Dear Experts,

I am trying to built an electronics controller for a high power DC motor.
I have done small powered circuits using transistors. But learned that these may have current limits. I like to know what is the usual way to handle high power operations using electronics.

The dc motor specification:

1. 12v.
2. 3 to 4 amps max.

thank you for reading.

sincerely
Ramone

Dear Experts,

can you give me some clues on how i can turn a digital circuit when the current passing through has to be around 3 or 4 amps for a dc motor?

if i use a transistor as switch, it certainly cannot handle the current.

how is it done?

thanks for reading.
regards
ramone
 
Ok, case closed.
I found out how to do it.
It can be done using something called the high power transistors.

cheers.

I just joined, and I'm a power electronics and motor driver designer. It's too bad nobody helped you here.
