Show us your Motor

Hi all Stereophiles!

I'm trying to put together a cross reference to make finding replacement turntable motors easier. So next time you have the bottom cover of your deck, scribble down the numbers on the motor (and the value of the phase shift capacitor if possible) and post them here (please!)

Here's what we have so far, it pretty thin but I only started last night (all 230V UK):

Linn LP12 (late]

110V

50Hz

250rpm

Premotec 9904 111 31819

Pink Triangle PT1 / PT2 (A/C version)

110V

50Hz

250rpm

Airpax 9904 111 31807

Rega Planar 2 (early)

110V

50Hz

250rpm

Unbranded 9904 111 04082

Rega Planar 2 (1994)

110V

50Hz

250rpm

Airpax 9904 111 31813

Rega P2 / P3

110V

50Hz

250rpm

Premotec 9904 111 31813

Systemdek IIX (early)

110V

50Hz

250rpm

Philips 9904 111 31807

Systemdek 2X2

110V

50Hz

250rpm

Airpax 9904 111 31818

Technics SP10 mkII

Brushless DC

SFMZ102-01E

Technics SP10 mkIIp

Brushless DC

SFMZ102-01E

Thorens TD 166 mkVI

16V A/C

50Hz

Unmarked

Re: Show us your Motor

OK just a couple more additions for now, keep them coming.

Linn Basik
110V
50Hz
250rpm
Airpax 9904 111 31818

Thorens TD150 (mk 2)
16 pole
AC 120 Volts
regulated by mains frequency at 50hz or 60hz
platter speed is determined by pulley diameter

Thorens TD160 (mk 1)
AC 16 pole 120 volts
regulated by mains frequency at either 60hz or 50hz
platter speed is regulated by pulley diameter

Regards,
JaS

Re: Show us your Motor

MOst of the Thorens were Berger-Lahr motors. I will root around and find the data on a few others I have lying about.

Thorens TD-521
Berger-Lahr RSM 50
8VAC!

I'm looking for various alternatives to replace my motor in an Rega Planar 2 (early)


Hi, The Rega decks all use Airpax or Premotec branded 9904 series AC synchronous motors. Late decks use the upgraded Premotec 9904 111 31813 which is designed specifically for turntables and has lower vibration (and power) than either the Airpax 04082/31813 or the Premotec 31304 used on current Goldring decks. You will need to get the correct frequency for the mains in your country (US 60Hz / Europe 50Hz) and possibly change the phase shift capacitor and voltage drop resistor. For the 3.5W 31304 motor the capacitor value is 0.39 microfarad and for the 1.8W 31813 0.22 microfarad. These motors often turn up cheaply on ebay with the power supply board.

Goldring GR1
110V
50Hz
250rpm
Premotec 9904 111 31304
Capacitor 0.39 microfarad

Re: Show us your Motor

Hi, I am looking for a replacement direct-drive motor for a British JBE III T/T ref MKL 153B I think it is an 8 slot 24 pole or visa versa. Can you help me find who made and or makes an alternative of high quality. Tony

Re: Show us your Motor

Your info is excellent. Good work. Does anyone know if I can replace my systemdek iix motor (9904 111 31807), 110v, 250rpm, 50 hz. with a motor pulled from a rega P3. I know the voltage and rpm are the same but will the spindle pulleys be the same gauge and height.

Re: Show us your Motor

AirPax used to be a Philips div. the numbering sequence on the motors you listed are Philips catalog numbers. You could serach Philips as well as Airpax. Airpx stuff is available in Newark catalog www.newarkinone.com Maybe Allied www.alliedelec.com I recently got an Airpax ckt breaker for a Hv supply from almost 20 years ago, Airpax still makes a lot of the older stuff it looks like. It works, why change it.
