Seems that the motors have been rewound in the past, but whoever did it changed the winding setup. It's the only way to explain why they are 12 wore not 6, and why the windings differ from motor to motor.
They do seem to work ok. they just get alot hotter than the other motors of the same type.
Strange thing is I checked the resistance of the windings in the motors.
the 1.2a motor is 35.5ohm, the 1a motor comes in at 50ohm, and a third motor of the same type drawing 0.7a has 68ohm windings. the...
That's what I expected too. We have other 12 wire motors which are connected in 1delta to run on 220v and are fine. but this one drew 2.6A, which is a step in the wrong direction.
Only data I have on the motor current is what they should draw from the nameplate and what they do draw. Although I...
Should have a photo of the motors name plate with this post. I'll be able to get the whole motor tomorrow.http://files.engineering.com/getfile.aspx?folder=fdb2ac9c-00be-457c-9104-956578cbc35b&file=20160914_124231.jpg
Hi, I've come across a strange problem with a couple the tiny (0.089kw/0.12hp) motors at work.
Both motors are identical. We run them on 220V 50hz. According to the name plate they should draw 0.72A, but they don't. Even without a load one draws 1A and the other 1.2A. To make things more fun the...
