Patent number: 11519465Abstract: A pump includes a stator and a rotor axially between a fluid inlet section and a fluid outlet section. The stator includes a plurality of radially inwardly extending legs; and a plurality of electrical windings disposed about the radially inwardly extending legs. The attenuating circuit includes a capacitor electrically wired in parallel with each winding and at least one switch electrically connected to the capacitor.
