The motor stator includes a plurality of windings. The brushless electric motor also includes a rotor shaft non-rotatably connected to the motor rotor for rotating with the motor rotor and a resolver position sensor including a resolver stator and a resolver rotor configured for rotating within the resolver stator. The resolver rotor is non-rotatably connected to the rotor shaft for rotating with the rotor shaft. The resolver stator generates a signal based on a rotational position of the resolver rotor.

Abstract: A drive unit includes a motor and a rotor shaft operably coupled with the motor. The rotor shaft has an inner surface that defines a hollow that extends axially from a first opening at a first end of the rotor shaft to a second opening at a second end of the rotor shaft and has a tapered portion that tapers radially inboard as the tapered portion of the inner surface extends axially away from the second end of the rotor shaft. The rotor shaft further defines a plurality of ports disposed axially between the tapered portion and the second end of the rotor shaft. The motor is configured to drive rotation of the rotor shaft, such that a fluid disposed within the hollow is propelled axially away from the first end of the rotor shaft and through the plurality of ports defined by the rotor shaft.

Abstract: A soil modeling and mapping framework for use in precision agriculture analyzes remotely-sensed data pertaining to characteristics of one or more agricultural fields, and determines optimal sampling locations from information in remotely-sensed information, terrain derivatives and satellite imagery, to develop a customized sampling design for modeling soil properties in such agricultural fields that optimized for the particular landscape in such fields. The soil modeling and mapping framework then analyzes soil samples collected based on the customized sampling design in machine learning-based models that predict soil properties in sampled, semi-sampled, and unsampled target fields. The predicted soil properties are used to develop highly-accurate maps of soil properties such as fertility maps, which may further be used for defining and creating one or more management zones with recommendations for applying the right amount of nutrients at variable rates in the correct areas.
