12" Sprague Lundell ball motor Model 30024 completed

Recommended Posts

Finished up on this 3 speed oscillator, BB/BC Circa 1911 ball motor. I installed a bridge rectifier and now it's running on 119vdc. This is my first attempt to powder coating. I probably should have done more prep on the cast iron but I think I came out pretty good. It runs smoothly in 3 distinct speeds. I want to thank Darryl Hudson for a great job making me an oscillator shoulder screw, rubber grommets and feet. I also want to thank Tony Clayton for an awesome job on the wire he made.

Three wires broken on the commutator. Luckly my repairs worked!

 I've never seen that particular model. 

This model was introduced in 1907 12" and 16" models with no guard badge as a stationary fan only. It remained on the market through 08 season as stationary only with non-detachable rear motor housing end cap.

 

1909 introduced this model now with a detachable rear end cap for the OPTIONAL oscillating mechanism. The 1909 electrical trade offers this model 12" and 16" with NO guard badge.

Steve Rockwell made a big play finding the image on the right in 1912 electrical trade. That bugger sporting that badge slipped by me on numerous electrical trade scans from past. Electrical trade is well known for sharing same images of fan motors despite changes over a number of years. Lots to learn when doing research of the past and their methods.

Significant changes are announced in 16 electrical trade for the Lundell DC. What they don't share is exactly what are those changes. The blade is announced in 17 as changed to round tip wings. The entire fan is painted in black enamel. Good luck collecting all the Lundell/IC - Lundell/Sprague variations 1892-20.
