  • Synchronous Self-Starting AC Motor For L-103

    <BLOCKQUOTE>


    Hey yall'... figured I'd share my recent experience with you along with a question or two. I bought an L-103 locally for $50.... brought it up here to the apartment and pushed it next to my M3... they look like Bonnie and Clyde together...</P>


    So the L-103 wouldn't power up... I unscrewed the AO-43 amp and took a look underneath and lo and behold... a blown 2.5A 125V fuse was burnt out.... so me... being impatient at 3:00A.M. with no access to fuses.. bypassed it with a hard wired solder connection and turned it on.... it went Zzzzzffffppptttttt-POP!... and the next thing you know I'm at Tulsa Regional with third degree copper slag burns on the left side of my face.... go figure... the bearings at each end of the the motor were seized up due to non-lubrication and the fuse must've blown trying to spin it.... </P>


    So now I'm in search of another self-starting motor.... I understand these are late Hammond motors and that the Organ Service Company's only tech who worked on them is..... no longer with us..... not that he could have fixed this thing without replacing the core.... My question here is that I've found several very similar start motors from various sources on eBay but they are different colors with different labels... but same manufacturer "Howard Industries- Racine Wisconsin"... so are all these motors electromechanically identical or????? The part # on the housing is AO-24240-(1).... specs on the label listthe following:</P>
    <UL>
    <LI>SPN= 5.26-0013</LI>
    <LI>H.P.= 10 (M?)</LI>
    <LI>RPM=1800</LI>
    <LI>CYC= 60</LI>
    <LI>DUTY= CONT 40 degrees C</LI>
    <LI>AMP= 31</LI>
    <LI>VOLTS= 115</LI>
    <LI>MFD= 3 (?????)</LI>
    <LI>VAC= 330</LI>
    <LI>FRAME &amp; TYPE= PCS 2624 Z S0</LI>
    <LI>WATTAGE= 32 Watts</LI>[/list]


    Any help would be greatly appreciated..... and just for good measure I've included afew picutres... both of my new L-103 and the notorious motor that sent me to the emergency room at 3:00 in the morning... lol...:)</P>

    Hi, Noah-</P>


    Sorry to hear about your accident. Next time you give anything electrical the smoke test, stand clear for your own safety. I just looked at the data plate on a motor I pulled from an '72 Hammond H-395 a while back and the specs on its data plate are the same as those you posted. It does differ in that the shaft extends out both ends to spin the vibrato and celeste scanners in addition to the generator. My Wurlitzer Spectratone 300 tone cabinet also uses a Howard Indstries motor, but of a different design.</P>

      Knowing Hammond's hatred for Donald Leslie.... I'm surprised he didn't go nazi on Howard Industries for supplying his competitors with AC motors.. lol.... *another Grease Pit topic.. yay!*</P>


      Wow... a double drive shaft for vibrato and celeste... someone had the right idea ;)</P></BLOCKQUOTE>
