Title: Coreless servos ? Post by: gauravag on August 09, 2009, 08:02:35 AM Hi everyone ?
I wanted to know the pros and cons of a coreless servo. I understand that there are both coreless standard and coreless digital servos available. Would appreciate if the knowledgeable here can share the benefits of this. I have never used these, but might consider one for one of my projects. Thanks ! Gaurav Title: Re: Coreless servos ?
