What are the two wires of a motorcycle high-voltage coil?
1 Answers
Motorcycle high-voltage coil has two wires: primary coil and secondary coil. Here are the related details: 1. Material: A typical high-voltage coil (ignition coil) contains two sets of coils—primary and secondary. The primary coil uses thicker enameled wire, usually around 0.5-1 mm in diameter, wound approximately 200-500 turns. The secondary coil uses thinner enameled wire, typically around 0.1 mm in diameter, wound approximately 15,000-25,000 turns. One end of the primary coil connects to the vehicle's low-voltage power supply (+), while the other end connects to the switching device (circuit breaker). One end of the secondary coil connects to the primary coil, and the other end connects to the high-voltage output terminal to deliver high-voltage electricity. 2. Ignition Coil: The ignition coil transforms the vehicle's low-voltage electricity into high voltage due to its similar structure to a conventional transformer, with the primary coil having a higher turns ratio than the secondary coil. However, the ignition coil operates differently from a conventional transformer. A conventional transformer works at a fixed frequency of 50Hz, also known as a power-frequency transformer, whereas the ignition coil operates in pulse mode, functioning as a pulse transformer. It repeatedly stores and releases energy at varying frequencies depending on the engine's speed.
