I need a diagram for 1PH, reversible motor via two contractors. Uglies have it but mines not here. 240v.
FIFY.I need a diagram for 1PH, reversible motor via two contactors. Uglies have it but mines not here. 240v.
Marketing conspiracy with eyeglass manufacturers. :roll:...Why do they keep making labels smaller and smaller?
Thanks.
Quitting time and had to call both of my help from their jobs while I went for a motor. One went to shop for lifting equip while other started dismantling old. Dark by the time we got the old down and new in place. Then still had to decipher 40 yr old connections vs new with wind trying to blow you off the bin top. Phones dead from being used as Flash lights and wind noise made radios worthless or close to it. Quit until daylight even though it will be colder today. Hopefully it is dry.
Why do they keep making labels smaller and smaller?
You must be using an iOS device. I can't get mine to recognize contactors either, it keeps autocorrecting to contractors too. PITA...Dang spell check.
It does not give you the option of adding contactor to your personal dictionary?You must be using an iOS device. I can't get mine to recognize contactors either, it keeps autocorrecting to contractors too. PITA...
Did you mean zero amps on the start winding? If it's a cap start, cap run motor the starting winding would stay in.At least it is not dark. Colder & windy though.
Not sure if we have it correct so checked the current on the run windings, about 10 amps for the brief time I left it on. I was expecting zero, but maybe the start switch is just cutting out the start Caps and not the windings. Motor sounds right.
Weg. 7.5 hp 230volt single voltage reversible.
Thank you. That is what we figured out. My local motor shop was no help. It switches out the start caps, leaves start winding in.Did you mean zero amps on the start winding? If it's a cap start, cap run motor the starting winding would stay in.
I have never seen such a circuit in person. It effectively shorts out the starting caps leaving both windings (with an angular offset) connected?Thank you. That is what we figured out. My local motor shop was no help. It switches out the start caps, leaves start winding in.

Are you sure this is not a capacitor start-capacitor run motor where the winding is still energized out of phase, but with a smaller value capacitor to keep the appropriate phase shift with the higher running impedance ?
Would have been most beneficial for patrons and participants if you gave the full model number......

Sure would have but I took three pictures of the label and none ended up with a readable any thing. Either I was shaking in the wind to much or the flash obscured the details.Would have been most beneficial for patrons and participants if you gave the full model number...

Whoosh...huh?...er yeah that sounds uh, AD, I'll let you handle this one...I have never seen such a circuit in person. It effectively shorts out the starting caps leaving both windings (with an angular offset) connected?

The starting caps don't short, they drop out. The starting winding stays energized through a running cap that also limits the current.I have never seen such a circuit in person. It effectively shorts out the starting caps leaving both windings (with an angular offset) connected?
