  • What is the stator of a BLDC motor?

    Like all other motors, BLDC motors also have a rotor and a stator. Similar to an Induction AC motor, the BLDC motor stator is made out of laminated steel stacked up to carry the windings. Windings in a stator can be arranged in two patterns; i.e. a star pattern (Y) or delta pattern (∆).

  • What material is used for BLDC stator?

    Yes, a slotless BLDC motor stator is typically made up of laminated steel sheets, similar to the stator of a traditional slotted BLDC motor. However, the manufacturing process for a slotless stator is different, as there are no slots or teeth to form winding slots.

  • Does a brushless motor have a stator?

    In a brushless DC engine, you put the permanent magnets on the rotor and you move the electromagnets to the stator. At that point, you utilize smart electronics to energize the electromagnets as the pole turns.

  • What does a stator do in a brushless motor?

    In brushless DC motors, the permanent magnets are on the rotor, and the electromagnets are on the stator. A computer then charges the electromagnets in the stator to rotate the rotor a full 360-degrees.

  • What are the different types of brushless motor stator?

    There are three classifications of the BLDC motor: single-phase, two-phase and three-phase. This discussion assumes that the stator for each type has the same number of windings. The single-phase and three-phase motors are the most widely used.
