The multiple core assemblies are contained independently and spaced apart from each other along the circumference of the rotor. The housing cover includes a second bearing housing supporting the other side of the shaft. The motor housing includes core support portions for supporting the multiple core assemblies independently, and a first bridge extending from the core support portions to connect the core support portions and the first bearing housing.
