Brushless direct current motor and electric power steering system comprising same
A BLDC includes an outer casing, and a first sub-motor and a second sub-motor mounted within the outer casing. The BLDC further includes a terminal hub, and a first conductive terminal set and a second conductive terminal set. The first and second sub-motor include their respective stators that are energized independently and a common rotor. The first conductive terminal set is configured as a power supply branch circuit for the stator of the first sub-motor, the second conductive terminal set is configured as a power supply branch circuit for the stator of the second sub-motor. The first and second sub-motors can be configured to selectively commonly operate as a single motor to output normal power or operate independently. When one sub-motor fails, the other sub-motor can independently operate to ensure reliability and safety of the motor.
