IDM, Iskra, AET Magnetos

  1. Tomos Magnetos 
  2. Service Info

 

  IDM magnetos, made in Italy, are on some early-to-mid-1990’s Tomos. They are CEV-compatible, and have the same appearance.

Iskra magnetos are made in Slovenia (which was part of Yugoslavia before 1991). They are original equipment on most Tomos mopeds from 1989 to 2007.

  AET  After about 1993 Iskra magnetos were labeled AET. Iskra electric motors, AET electric equipment and Tomos mopeds were (or are) divisions of Hidria, a family of Slovenian manufacturing companies. Iskra-AET magnetos have the AET logo stamped on the flywheel, and the Iskra name cast into the back side of the stator base plate. So they can be called by either name.

Tomos mopeds, USA models, had many magnetos, but many were interchangeable. The magneto brands Ducati, ZEM, CEV, IDM, and Iskra-AET, each had different versions. They are all listed below, in order of VIN code and year range.

In 1998 the 230.327 magneto changed to a “4-star” or “plus sign” design. 3 of the 4 coils were for lighting, connected in series, and one coil was for ignition. So the output wires did not change. The base plate screws changed, from three 4 mm, to two 5 mm.
1974-1997 engine cases had only mounts for 3-M4-screw stator plates.
1998-later engine cases had mounts for both 2-M5 and 3-M4-screw base plates.

In 2003 the engine case, on all models, became electric-start-ready. The magneto did not change, but the magneto part number did because a rubber grommet was added.

In 2001-02 the A35 Revival was the first Tomos with electric start. The 230.842 magneto was the same as a 230.327, except it had an extra wire for battery charging, and a large flat gear on top, for electric starting.

On A55 Engines 2004 to 2017

In 2004-05 the A55 engine came out. It was cleaner and more efficient, to meet new 2006 EPA pollution standards. The A55 had a different magneto with an external pulser, which added two more wires.

In 2014 new US EPA air pollution standards came out. That contributed to Tomos’s (actually Hidria’s) decision to quit selling mopeds in the USA in 2013. 37 years of continuous US-model moped production, 1976-2013, came to an end. Tomos continued moped production for the European market.

In 2017 new US-model Tomos mopeds were once again being sold.

Engine cases: You don’t have to know the year or model to know what magneto(s) fit at particular Tomos. You only have to know what left-side engine case it has. The stator plate has to fit the engine case, and the flywheel has to fit the crank.

 

From 1974 to 1997 there were three M4-0.7 thread stator plate holes, for A3 and early A35. 3 total.

From 1998 to 2002 two M5-0.8 thread stator plate holes were added, for mid A35. 5 total, 3 unused.

From 2003 to 2006 the electric start affected the wires grommet, for late A35. 7 holes total, 5 unused

From 2003 to 2013 two M6-1.0 thread pulser coil holes were added, for A55. 7 holes total, 3 unused.

 

Flywheels: All the flywheels, both 80 and 90 mm ID, fit the same crank, but they can have different points cams or ignition triggers. Some flywheels do interchange, some might, and some don’t.
