摘要： 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.

摘要： 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.

摘要： 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.
