Abstract
A drive system for a fluid displacement pump includes an electric motor, a drive coupled to the rotor at a first end of the electric motor, a pump including a fluid displacement member mechanically coupled to the drive, and a controller configured to control a level of power to the electric motor based on a pressure setting set by a user. The electric motor includes a stator and a rotor disposed on an axis. The drive coupled to the rotor converts the rotational output to a linear, reciprocating input to power a pump.
