The molded structure includes: a first portion formed to axially constrain the bearing within the center pocket on one side of the radial body, and a second portion forming a support structure projecting from another side of the radial body to structurally support the positional sensor circuit board relative to the rotor.

Abstract: A method of operating a power tool having a motor and a controller is provided. The method includes: receiving a speed signal from a variable-speed input mechanism mounted on the power tool; determining a target speed of the motor corresponding to the speed signal; controlling a supply of power to the motor based on the target speed; determining an underspeed threshold corresponding to at least one of the target speed or the speed signal; determining a rotational speed of the motor; and interrupting a supply of power to the motor if the rotational speed of the motor meets a criterion in relation to the underspeed threshold.

Abstract: The present invention is directed to a battery powered mower with a low profile design that minimizes the height of the mower to make the mower easier to operate and store. The low profile design places the cutting blade motor in the center of the deck volute so that it doesn't extend above the volute. Additionally, the batteries do not include a cover and so holes are located within the housing to drain away any water that collects. The invention also covers a simplified manufacturing process for the terminal blocks for the battery and a rear door. Lastly, the invention includes a cable guide to prevent the electrical cable from pinching when the handle is folded for storage.

A motor-fan assembly is mounted in the housing and arranged to generate an airflow along an airflow path from a dirty air inlet to an air exhaust. A retractable nozzle defines the dirty air inlet and is moveably mounted on the housing. At least a portion of the retractable nozzle is arranged to move between a retracted configuration within the housing and a deployed configuration outside the housing. The portion of the retractable nozzle in the retracted configuration is aligned in a direction along the longitudinal axis and the portion of the retractable nozzle in the deployed configuration is aligned in a direction across the longitudinal axis.

The transmission mechanism may employ a compound, stepped, planetary gear assembly, to provide for an axially compact arrangement of transmission mechanism components, to reduce an axial length of the tool. The speed selection mechanism may employ a multi-staged grounding device, corresponding to the reduced axial length of the transmission mechanism.
