5 Questions
What is the major difference between a BLDC motor and a DC motor?
BLDC motor does not have brushes, while a DC motor uses brushes for commutation
What powers the permanent magnet of a BLDC motor?
Electrical current through an electronically commutated system
What is the function of a physical commutator in a DC motor?
Changes the motor phase at the appropriate times for torque production
How does a BLDC motor differ from a synchronous generator?
BLDC motor is electronically commutated, while a synchronous generator uses a physical commutator
What characteristic does a BLDC motor share with a DC motor?
