Abstract
A fluid moving apparatus includes an electric motor having a rotor and a stator and a fluid displacement member. The rotor rotates relative to the stator on a common axis to generate a rotational output. The rotational output is provided to the fluid displacement member to power the fluid displacement member to one of move linearly along and rotate about the common axis. The stator includes one or more coils configured to power rotation of the rotor. The one or more coils extend circumferentially around and can be coaxial on the common axis.
