ELECTRIC PUMP Russian patent published in 2007 - IPC F04D1/12 F04D13/06 

FIELD: pump engineering.

SUBSTANCE: electric pump comprises asynchronous motor whose housing is rigidly connected with the lid of the pump base and is made of two shields that define a ring space. The space receives magnetic circuit of the stator provided with the exciting winding. The magnetic circuit of the stator is separated by an air space from the magnetic circuit of the rotor with short-circuited windings mounted in the space between the magnetic circuits of the stator. The rotor of the motor is sectional and is made of the central disk and safety clutch made of two clutch members fit on the shaft of the rotor. The disk of the rotor is freely mounted on the cylindrical surfaces of the clutch members. The clutch members engage the rotor disk by means of spring-loaded balls mounted in the axial opening in the hub of the disk and set in the radial grooves made in the ring collars of the clutch members.

EFFECT: reduced sizes and cost.
