In which type of BLDC motor the direction of the output current can't be changed?

Right Answer is:

Unipolar BLDC

SOLUTION

In a unipolar BLDC motor, the direction of the output current cannot be changed. Here, each phase consists of two sets of coils, But only a single set of them can be excited at a time. Hence, only half of the winding is used in this motor. In this motor, both the mechanical phases and the electrical phases are equal.
