Abstract: An electric motor including: a frame; a rotor assembly including a magnet, a bearing assembly, an impeller, and a shaft; and a stator assembly including a stator core and a bobbin. The frame has an inner wall and an outer wall, the outer wall surrounds the inner wall and defines an annular channel between the inner wall and the outer wall, and diffuser vanes extend from the inner wall to the outer wall through the annular channel. The inner wall defines a bore for supporting the rotor assembly, and the outer wall defines a substantially cylindrical outer casing of the motor.

Abstract: A compressor has a stator assembly, a rotor assembly, and a housing within which the stator assembly and the rotor assembly are located. The housing has a first end, a second end, and an air inlet disposed between the first and second ends. The compressor has a flow guide disposed within the air inlet. The flow guide is configured to split air flowing through the air inlet in use into a first airflow toward the first end of the housing and a second airflow toward the second end of the housing.

Abstract: A four-pole stator assembly including a bobbin assembly; and two c-shaped stator cores, each c-shaped stator core comprising a back and first and second pole arms extending from the back. The bobbin assembly includes first and second bobbin portions, each bobbin portion comprising two hollow bobbin arms, each bobbin arm defining a slot for receiving a pole arm, and a winding wound around each bobbin arm. The c-shaped stator cores are arranged such that each c-shaped stator core bridges across both bobbin portions with one of the first and second pole arms extending through a slot in the first bobbin portion, and the other of the first and second pole arms extending through a slot in the second bobbin portion, the pole arms being fixed in the slots by adhesive.
