Indeed, BLDC doesn't use EM induction to excite the rotor, instead it uses directly macroscopic magnetic force due to current in stator acting on the permanent magnets in the rotor.
The EM induction is present in the winding of the stator, and to some extent has to be present, to keep the current there low enough, otherwise we would get locked stator situation, and the winding would burn out.
