I have a Santa fibre optic decoration that has a TYC-30 AC6V 5RPM (.8-1W) synch. motor that's very noisy so I want to replace it. I can't seem to source a 6V version of this motor from the inter-webs. So my question is can I put a TYC-30 AC12V 5RPM in its place or will it simply not even run? The Santa's AC Adapter's output is 6VAC 1A 6W.

I wasn't sure if the 12V rating on the motor was an "Up to" 12V or "Requires 12V" to run.

Thanks for any help.

  • \$\begingroup\$ What does the data sheet say? For the most part, the 12V is nominal motor voltage. You can give it a bit more or less, but it will run faster or slower. And at some voltage less than its nominal, it will stall out. So It depends. \$\endgroup\$ – Passerby Dec 1 '15 at 18:36
  • \$\begingroup\$ Passerby, I'll try to dig up a data sheet on it, but did just notice the 12V AC motor said "operates at 10-12V", so sounds like 6V will stall it. \$\endgroup\$ – Kevin C Dec 1 '15 at 18:40
  • \$\begingroup\$ it's not going to run slow. it's a synchronous motor, it runs at line frequency. \$\endgroup\$ – Jasen Dec 1 '15 at 20:12

a synchronous motor will have lower torque at reduced voltage, if the load is light enough it will work, if it is not the motor won't move.
