CDI Ignition and Motorcycle Parts: What You Need To Know

Steven Spielberg

Understanding the basic parts and components of your motorcycle is vital to help the owner take proper care of it and ensure that their bike is working efficiently at all times. CDI ignition, motorcycle stator, and any other motorcycle parts might appear too complex for beginners. Take the time to read below and find out more information about what role they perform when riding your motorcycle.

CDI Ignition

CDI, or Capacitor Discharge, Ignition is one of many automotive electronic ignition systems that are often used for powering small engines, cars, turbine-powered aircraft, and motorcycles. It was invented in order to address the long charging times that were very common with high inductance coils. It first emerged into the automotive industry way back in the 1980s.

When used on vehicles and motorcycles, the basic principle in the use of a CDI ignition relies on electric induction from the coil to generate electricity that is capable of bursting the spark plug. Most CDI modules are made up of a small transformer, triggering circuit, charging circuit, and main capacitor. CDI systems vary in terms of the amount of energy it can store, which is typically around 50 mJ or more.

Motorcycle Charging System

Any motorcycle will mostly make use of a battery, either to buffer a certain amount of electric energy or to provide power that will get the bike running. However, the battery needs to be charged in order for it to perform any of these functions. Ideally, it must be charged at 14.4 Vdc in order to product enough voltage at certain engine speeds.

There are currently two basic systems used for charging motorcycle batteries. The first one is the Permanent Magnet Generator System, wherein a winded copper wire on the motorcycle stator helps to produce power. Meanwhile, the second system is called Field Controlled Generator System. This one works similar to a permanent magnet generator but without the use of magnet, instead it relies on an electromagnet to generate that magnetic field. This is similar to a car’s charging system.

Motorcycle Stator

The stator is a stationary part of the motorcycle’s alternator, which can be complicated for beginners to understand so it is important to have a look at the basic electrical system used on a motorcycle. It is an important part of any vehicle in order to produce and store electricity that will be used later on for operating it. The alternator is responsible for producing AC to turn on the tail lights, halogen bulbs, and the ignition systems. Since battery cannot be utilized to store the AC, it must be converted into direct current or DC instead for storing.

There are a number of designs available for a motorcycle stator in the market today, but most of them observe the same basic principle. Moving a magnet through a coil helps the coil to generate a burst of electricity. The length and amount of winding components to a stator will vary depending on the power requirements for your motorcycle and ensure optimum power output on your vehicle.

Now that you have some insight into the function of CDI ignition and other aftermarket motorcycle parts, it will enable you to know about which to buy in case you need to get a replacement. If you are still not sure, you can always consult a professional to get advice on making the right purchase.
