Magneto ignition restoration

We are specialized in restoration of vintage ignition magnetos. This includes the following services:

- Rewinding of coils

- Restoration of magnets and magnetic power

- Resetting bearings,, clearances, timing, contact breakers and overall fitment

- Complete overhaul of a magneto ignition

Strenghtening a magneto

We have the possibility to make any magneto better than it ever was. Originally most magneto's use horseshoe magnets or ringmagnets of tungsten steel or later AlNiCo type. These lose strength over the years due to environmental influence or heat. Most times these can be remagnetized to a sufficient amount for working, but almost never back to it's original strength for full reliability.

With over 10 years of experience in magneto ignition, and also years of research into windings, we have to possibility to re-energize your magneto with rare-earth magnets which in a very small area can house a lot more magnetic energy. 

This energy can only be converted into a strong spark when coil windings are fitted to suit this added magnetism. This is where the advantage of research and experience comes in.

The conversion is invisible on the outside, even the original horseshoe magnets will remain in place. The result is much more reliable starts due to low RPM power, quicker pickup on the engine and less vulnerability to misfires due to enriched mixture.

Brushless motor manufacturing 

Retrofit solutions

Prewar Workshop is a manufacturer of retrofit electric motors for vintage car applications. Any broken old DC brushed motor can be adapted to modern brushless DC technology invisible to the outside.

- Electric window winding motors

- Electric seat motors

- Windshield wiper motors

- Electric roof motors

The old housings will be re-used so the change is invisible on the outside, the new motors are maintenance-free brushless and can be installed in any environment where a brushed motor fitted before.

The motors range from 25 to 55 mm diameter and can output up to 0,5 kW of power, plenty for any application where a brushed motor was previously used

Every motor is manufactured in EU and hand fitted to each vintage car application.

Custom motor manufacturing

Apart from retrofitting exising motors with BLDC internals, we can also build a complete custom motor. These custom motors can be specified to your need in power, performance, durability etc.

If you have an inquiry for a custom motor, please contact us for the possibilities.
