High power to weight ratio: Despite its light weight, the XBD-1219 has a high power to weight ratio, which means it can deliver a lot of power relative to its size and weight.
Reduced inertia: The lack of an iron core in the motor reduces the inertia of the rotor, making it easier to accelerate and decelerate quickly.
Long lifespan: The coreless design also reduces the risk of core saturation and extends the lifespan of the motor, despite its lightweight construction.
