Abstract: An insulation seat of a slim reel-type brushless motor includes a ring-shaped bottom plate, an inner plate and an outer plate. The ring-shaped bottom plate has an opening. The inner plate is arranged around the opening. At least one upper locking element is protruded upwardly from the inner plate. At least one lower locking element is protruded downwardly from the inner plate. The upper locking element and the lower locking element are staggered. The outer plate is arranged around an outer periphery of the ring-shaped bottom plate. An accommodation space is defined by the ring-shaped bottom plate, the inner plate and the outer plate. A coil is disposed within the accommodation space. The at least one upper locking element of the inner plate is engaged with a first magnetic seat. The at least one lower locking element of the inner plate is engaged with a second magnetic seat.
