Alternative Gyro SE Motors?

Post by watchnerd » 15 Jan 2017 21:10

Are there altnernative motors for the Gyro SE?

I've bought a used one without a motor. Paying $900 for an official Michell replacement seem ridiculous for a simple electric motor with a pulley.

While I agree $900 is too much, it is not simple. The motor determines the sound quality. You don't want to compromise.

Two options:


1) hunt the various audio forums and classifieds sites for a leftover AC motor and supply, from someone who went DC.

2) DIY - if you know what you are doing

-purchase a pulley
-purchase a suitable DC motor (Maxon or Premotec, precious metal brushes, coreless, sleeve bearings, running at some 1000 rpm at 9V DC)
-build a controlled and regulated DC supply, with trimmers for speed adjust
-purchase a Rega armboard
-drill the armboard's hole wider
-make a top plate, suspend the motor on it, attach to the armboard with something compliant like Blutac
-remove the Gyro's chassis counterweight at the left side
-put the construction on the left Mickey ear

No, I don't sell parts and I don't provide circuit diagrams. I am done with these things.

I was actually just now looking at the outboard Pro-Ject motors from the RPM series and wondering if it would work.

maybe an OriginLive Advanced-DC-motorkit could be a cheaper solution?

Funny you should mention it, as I just wrote to them. They can fabricate a pod / housing for the motor.
