    I can't give much history but my home built mill with !/2HP 180v DC motor powered by a cheap Chinese speed controller does everything that I want. Les Jones 1: 22/02/2015 18:06:27: 2165 forum posts 149 photos : Any motor with brushes will need them checking and replacing from time to time. It would also be worth cleaning out the carbon dust that results from the brushes wearing. Les. NeilОнлайн-запрос

    Many mills and components still prefer DC variable speed, variable torque drives. These are energy efficient as they only require the amount of energy required to do the work. If a motor has 5,000 HP and only 1,000 HP is needed to do the final pass, it will only use 1,000 HP. Another benefit of modern electronic DC technology is the fact that you eliminate many relays and expensive conduit andОнлайн-запрос

    20/05/2010· Rolling mill DC motors are best at low speed, high torque applications, while AC motors typically need to run above 800rpm to be cost effective. Also the case for higher efficiency of AC motors is many times negated by the wasteful braking methods of some AC drive systems.
