Abstract
A rotational output assembly is configured to provide power to a drive assembly to cause pumping by a pump. The rotational output assembly includes an electric motor having a stator and a rotor. The electric motor is supported by a pump frame that also supports the pump. The pump frame at least partially defines a gear chamber. The electric motor is mountable to and dismountable from the pump frame while maintaining connections of the pump frame that define the gear chamber
Claims20
A fluid pumping assembly comprising:
- a pump frame at least partially defining a gear chamber;
- a drive gear supported by the pump frame;
- an eccentric that receives rotational motion from the drive gear;
- an electric motor comprising a stator and a rotor configured to rotate on a motor axis, the electric motor supported by the pump frame such that the rotor and the stator are disposed outside of the gear chamber;
- an eccentric that receives rotational motion from the drive gear;
- and
- a pump mounted to the pump frame, the pump configured to receive reciprocating motion from the eccentric;
- wherein the electric motor is mountable to the pump frame and dismountable from the pump frame while maintaining connections of the pump frame defining the gear chamber.
