Applications
Q: Can a frameless BLDC motor be used directly?
A: No, a frameless BLDC motor cannot be used directly out of the box. Since it does not include a housing, shaft, or bearings, it must be integrated into a custom mechanical structure. Proper alignment, mounting, and thermal management are essential. Additionally, it requires a compatible motor controller and, in most cases, an encoder or position sensor for precise operation.
