Abstract: A brushless direct-current motor is provided includes an inner stator and an outer rotor. The rotor includes a rotor core disposed around the stator, an inner annular member mounted on a rotor shaft, and a plurality of radial blades extending angularly from the rotor core to the inner annular member forming a fan. A first end cap is provided including a radial back plate proximate the fan and a center opening in the radial back plate through which the rotor shaft extends. A second end cap is provided including a main body disposed adjacent the stator opposite the fan. The radial back plate of the first end cap includes at least one sloped surface forming at least one air gap such that the airflow generated by the fan is centrifugally guided within the first end cap by the sloped surface and caused to exit through the air gap.

Abstract: A compacting power tool comprising: a housing; a motor; a reciprocating drive mechanism coupled to the motor; and a compacting foot coupled to the reciprocating drive mechanism and configured to engage a surface to be compacted; and a controller configured to receive at least one motor signal and to determine a change in the operational load of the motor based on the received at least one motor signal when the compacting foot is not engaging the surface to be compacted.

Abstract: A compacting power tool comprising: a housing; a motor and a first electrical storage electrically connected to the motor mounted within the housing; a reciprocating drive mechanism coupled to the motor; and a compacting foot coupled to the reciprocating drive mechanism and configured to reciprocate and engage a surface to be compacted when the motor is operating; and an energy capture system comprising a second electrical energy storage and at least one generator electrically connected to the second electrical energy storage, wherein the at least one generator is coupled to the reciprocating drive mechanism.

Abstract: A compacting power tool comprising: a housing; a motor mounted within the housing; a reciprocating drive mechanism coupled to the motor, wherein reciprocating drive mechanism comprises a reciprocating piston movable between a first position and a second position; a compacting foot coupled to the reciprocating drive mechanism and configured to reciprocate and engage a surface to be compacted when the motor is operating; and a controller configured to cause the motor to provide a first torque when the reciprocating piston is moving from the first position to the second position and to provide a second torque when the reciprocating piston is moving from the second position to the first position, wherein the first torque is greater than the second torque.

Abstract: A power tool or a mower is provided including brushless direct-current motor having an inner stator and an outer rotor. A rotor shaft extends through a stator core of the inner stator. The motor includes a first end cap disposed on a first side of the stator and supporting the rotor shaft via a front bearing and a second end cap disposed on a second side of the stator and supporting the rotor shaft via a rear bearing. The front end cap is mounted on a housing of the power tool or a deck of the mower while the rear end cap is located fully outside the housing or the deck.

Abstract: A brushless direct-current motor is provided includes an inner stator and an outer rotor. A rotor shaft extends through a stator core of the inner stator. A first end cap includes a radial back plate disposed on a first side of the stator and a front center opening through which the rotor shaft is supported via a front bearing. A second end cap includes an inner annular body extending axially inwardly and forming a rear center opening, an outer annular body, and a main body extending on a second side of the stator. The inner annular body includes a first portion that extends at least partially into an opening of the stator core and supports the rotor shaft via a rear bearing, and a second portion rearward of the first portion that received a rear end of the rotor shaft therein and houses a sensor board therein.
