[GreenKeys] ASR 33 motor buzzing

[Brad]

Pretty much when you engage the motor (Line or Local) there’s a visible flash from the fuse holder and then that’s it.  The motor does try to turn though each time.  It doesn’t *feel* like it’s inhibited in movement in any way internally.. but I don’t know what’s normal yet with these.

Sounds like a starting capacitor to me. They do dry up and go bad. If Wayne or Paul don't have one, I think I still have an extra. I bought several a year or so ago for $6 each. 

 

Easy check. When you first turn it on, use your hand to get the motor spinning in the right direction. If it is just a bad capacitor it might come up to speed and keep going. Or it might not, depending on how the capacitor has failed.

Okay so I think I may have a dead motor on my hands.  When I power my ASR on I hear a loud buzzing, and I can hear and feel it coming from the main motor.  However if I manually turn the motor shaft (clockwise), everything in the Teletype seems to move as it should, it’s not seized.  After a while it will blow the 2A fuse nearby.

 

Would that about be the right diagnosis?  Can the motors be rebuilt?

 

If anyone else has any other suggestions on stuff I can try, I’d be most appreciative.
