Power tool with compact motor assembly

A power tool includes a housing and a brushless motor with a rotor and a stator assembly. The motor defines a motor envelope bounded by a rear plane at a rearmost point of the stator assembly and rotor, a front plane at a frontmost point of the stator assembly and rotor, and a generally cylindrical...

Beschreibung
Zusammenfassung:	A power tool includes a housing and a brushless motor with a rotor and a stator assembly. The motor defines a motor envelope bounded by a rear plane at a rearmost point of the stator assembly and rotor, a front plane at a frontmost point of the stator assembly and rotor, and a generally cylindrical boundary surrounding a radially outermost portion of the stator assembly and rotor. A rotor shaft is rotatably driven by the rotor. A transmission includes an input member rotatably driven by the rotor shaft and an output member. A first bearing supporting the rotor shaft is at least partially received within the motor envelope. A second bearing supporting the rotor shaft or a component of the transmission is at least partially received within the motor envelope. A support plate supporting a component of the transmission may be at least partially received within the motor envelope.
