A magneto coil (often referred to as a stator coil or magneto‑stator assembly) for a 150 cc motorcycle such as the BM 150 is a key part of the electrical/ignition system. It is mounted inside the engine’s flywheel cover and works by generating the alternating current (AC) from the spinning flywheel magnets, which powers the lighting/charging circuits and triggers the ignition spark via the CDI unit. Replacement of this coil restores stable charging, reliable spark and overall electrical system health.
Specifications
Key Features
Wound copper wire coil and aluminium/alloy stator core designed for efficient electromagnetic induction.
Compatible with the BM 150 engine (fits model designation).
Designed to output sufficient electrical current for ignition trigger and charging circuits (12 V systems typical) under motorcycle operating conditions.
Durable construction resilient to vibration and heat, suitable for engine‑compartment mounting and exposure to oils and debris.
Direct replacement part: helps restore original electrical performance (spark strength, battery charging, lighting) when the original coil fails.
