Abstract
A brushless DC motor includes: a motor section which has a rotor, a stator and a housing; a control circuit section which is integrated with the motor section and separated from the motor section by a partition; and a casing member which covers the control circuit section to isolate the control circuit section from the external environment. A position detection means is disposed outside of a bearing member with respect to an axial direction.
