RE: Tubular motors
RE: Tubular motors
A client of mine has run 2 roller shutters off a single switch, this is against manufacturers reccomendations, I wanted to find out just exactly what happens when you do that. So i wanted to know what kind of motors they are, ive since found out.....5 mins ago they are
Split phase capacitor run
They aren't operating at all now and they are still in situ, I figured the start winding may have burned out they only consume a few amps (possibly 10 @ start up). They were connected direct to an incorrect mcb 32A ...whoops any thoughts

I think it does not allow that.

You apply power to TWO leads ONLY to make it go one direction. It is a PSC design that uses a capacitor between the forward and reverse leads (internally). So, putting motors in parrallel would mean there is no longer an open on the unused direction!
RE: Tubular motors
We normally use a group controller for this kind of control. How would this device prevent that from happening.
My customer didnt like the idea of replacing these motors and insisted on taking them to a motor rewinders...who then confirmed the windings were open and informed the customer that he couldn't rewind them for less than the replacement cost £350.00 each which obviously he has to pay now.
The 16th ed. wiring regulations does not allow motors to be controlled via the same switch either because motors are not allowed to share a protective fuse.

Is the problem increased because one of these motors is driving right handed and the other left handed, or doesn't it matter
No, the left hand/right hand makes no difference. You cant parallel the motors as the manufacturer says!
Each motor must be switched independently of the other.
