Abstract
A fluid transfer pump assembly that includes a motor enclosure assembly that forms a motor cavity sized to receive a motor. The motor enclosure includes a flame path that extends from an interior joint to an exterior joint. The interior joint faces the motor cavity and the exterior joint faces exterior of the motor enclosure assembly. A heat sink is located in the motor cavity of the motor enclosure assembly. A portion of the heat sink abuts the interior joint.
Claims20
A fluid transfer pump assembly comprising:
- a motor enclosure assembly that forms a motor cavity;
- wherein the motor cavity includes a motor having a rotor and a stator;
- and
- a motor controller that supplies power to the motor;
- wherein the stator includes a plurality of pole pairs of wire windings that can create a moving electromagnetic force to rotate the rotor;
- and
- wherein the motor controller, upon receiving signals of a condition of the fluid transfer pump assembly, directs current to at least one pole pair of wire windings on the stator at a voltage that does not cause the motor to rotate, and instead causes the at least one pole pair of wire windings to vibrate to generate a feedback signal.
A fluid transfer pump assembly comprising:
- a motor enclosure assembly that forms a cavity sized to receive a motor;
- wherein the cavity includes a controller that supplies power to the motor having a stator;
- wherein the stator includes at least one wire winding;
- and
- wherein the controller directs current to the at least one wire winding on the stator at a voltage that causes the at least one wire winding to vibrate to generate a status feedback signal.
A fluid transfer pump assembly comprising:
- a motor enclosure that forms a cavity;
- a motor having a stator;
- wherein the cavity of the motor enclosure receives the motor;
- wherein the stator includes at least one wire winding;
- and
- wherein the at least one wire winding on the stator vibrates to generate a status feedback signal.
