Hi,
It's going to operate in a regular environment, it doesn't have to last forever as it's just for experimental purposes, and the consequences of failure would be having to buy another motor. As long as it can rotate between 100 and 600 rpm for an acceptable period of time without burning...
Sorry, I should have been clearer on my description, by spindle I mean a fixed axle or 'pin', one end of which will be attached to the motor, the end of which will be pointed and rest in a cup, and the disk fixed in the middle. There'll be no friction from any sources other than the motor, the...
Nothing's going to be dropped on it, thrown at it, or fired at it. The disk will not mechanically interact with any other device - it's just going to spin. The rpm won't go below 100 or above 600, so an ability to easily change speed would be an advantage.
Hi,
Thanks for your replies, it's refreshing to find a forum where people actually respond to a post.
For an unknown reason I visualise the motor at the bottom, so with that in mind, the disk is 1000mm diameter, and 5mm thick, it will weigh a total of 1.5kg, including the spindle. The disk...
Hi,
I may well investigate the benefits of a vacuum in the future, but I'll be running the motor in normal pressure initially. What I really need to know is what would be the ideal electric motor given the job and the need for energy efficency.
Hi,
I want to spin a disk (dimensions = diameter 1000mm, thickness 5mm, weight (inc spindle) 1.5kg) at a continuous 500rpm in the most energy efficiant way possible. What would be the best electric motor, the best configuration (below the disk or above), and what would be the approximate...
