which current sensor can I use for BLDC Motor for sensing between -5A and +5A and the power supply voltage would be 24V ?

user4353247

Please suggest me good sensor to sense the current of the motor. I am also having little confusion on which side (High or Low) sensing is required for my project.

If you give your comment would be better for me to understand. Thanks for your time.

Hello,

I will look into what is our best option for you. Below are some training videos that can help you with your design decisions regarding current sensing. I would suggest videos number 1 and number 3.

Hello,
A question, what is the frequency response you require for your design?

Probable low frequency measurement. Not very sure about it,

If you dont mind, pls let me also focus on frequency response and how may I get to know what is the response required for my design?

is there any article help me understand this.

Thanks.

Can you provide a little more details on your design constraints. What is the end result you are trying to do with this current measurement? Do you have an initial schematic?

Regards,

Javier
