Abstract
Aspects of the disclosure relate to electrically driven power end apparatus and methods, and associated components thereof. In one implementation, a power end for a pump includes a crankshaft coupled to a plurality of actuation rods, and a motor. The motor includes a rotor coupled to the crankshaft. The rotor includes a plurality of electrical coils wound at least partially around the rotor. The motor includes a stator disposed radially outside the rotor, and the stator includes one or more magnets. The plurality of electrical coils apply a magnetic force to the rotor to turn the crankshaft when the plurality of electrical coils are powered.
Claims20
A power end for a pump, the power end comprising:
- a crankshaft coupled to a plurality of actuation rods;
- a motor, the motor comprising:
- a rotor coupled to the crankshaft, the rotor comprising a plurality of electrical coils wound at least partially around the rotor;
- and
- a stator disposed radially outside the rotor, the stator comprising one or more magnets, wherein the plurality of electrical coils apply a magnetic force to the rotor to turn the crankshaft when the plurality of electrical coils are powered.
A power end for a pump, the power end comprising:
- a crankshaft coupled to a plurality of actuation rods;
- a motor, the motor comprising:
- a rotor coupled to the crankshaft, the rotor comprising:
- a first portion disposed on a first side of a center of the rotor, the first portion comprising a first plurality of electrical coils wound at least partially around the first portion;
- a second portion disposed on a second side of the center of the rotor, the second portion comprising a second plurality of electrical coils wound at least partially around the second portion;
- and
- a stator disposed radially outside of the rotor, the stator comprising one or more magnets, wherein the first plurality of electrical coils generate a first magnetic force drawn to at least one of the one or more magnets in a first direction when powered, wherein the second plurality of electrical coils generate a second magnetic force drawn to at least one of the one or more magnets in a second direction when powered, the second direction being opposite of the first direction.
A power end for a pump, the power end comprising:
- a crankshaft coupled to a plurality of actuation rods, the crankshaft comprising a drive shaft;
- a motor, the motor comprising:
- a rotor coupled to the drive shaft of the crankshaft, the rotor comprising:
- a centerline axis extending through a center of the rotor,
- a first outer portion disposed on a first side of the center of the rotor, the first outer portion comprising a first plurality of electrical coils wound at least partially around the first outer portion,
- a second outer portion disposed on a second side of the center of the rotor, the second outer portion comprising a second plurality of electrical coils wound at least partially around the second outer portion,
- a third outer portion disposed on a third side of the center of the rotor, the third outer portion comprising a third plurality of electrical coils wound at least partially around the third outer portion, and
- a fourth outer portion disposed on a fourth side of the center of the rotor, the fourth outer portion comprising a fourth plurality of electrical coils wound at least partially around the fourth outer portion, and
- a stator disposed radially outside of the rotor relative to the center of the rotor, the stator comprising one or more magnets;
- wherein the first outer portion, the second outer portion, the third outer portion, and the fourth outer portion of the rotor define an inner circumferential perimeter, and the drive shaft defines an outer circumferential perimeter, the outer circumferential perimeter being within the inner circumferential perimeter.
