Latest Patents
Griggs' latest patents include a low-speed canned motor that features a unique design. This canned motor has an L/D ratio of less than 50, with one bearing on one end of the rotor assembly configured to resist longitudinal displacement of the rotor due to axial shaft load. The other bearing allows limited longitudinal displacement of the rotor assembly, accommodating thermal expansion and lengthwise adjustments. The rotor assembly includes a center shaft that extends coaxially through a hollow shaft, with rotor windings mounted on the hollow shaft. The design also incorporates a cap and nut assembly that allows for adjusting the effective rotor shaft length and facilitates the replacement of the rotor shaft without removing the rotor assembly from the motor. Another patent involves a canned motor comprising a rotor assembly with at least six poles, a stator assembly, and an isolating can that separates the rotor and stator assemblies. This design also features first and second frictionless bearings positioned on the rotor shaft.
