Electric motor

A power tool comprising:

• a housing;
• an electric motor including
• a rotor assembly including a rotor shaft, a rotor body fixedly coupled to the rotor shaft, and a plurality of magnets coupled to the rotor body, and
• a stator assembly at least partially received within the rotor assembly, the stator assembly including
• a stator mount having a stator support portion and a motor support portion, and
• a stator core assembly fixedly supported by the stator mount, the stator core assembly defining a central bore that receives the rotor shaft and the stator support portion;
• an adapter configured to fixedly couple to the motor support portion, the adapter including a first coupler;
• and
• a gear case including a second coupler configured to be received by the first coupler to removably couple the adapter to the gear case.

An electric motor comprising:

• a rotor assembly including a rotor shaft, a rotor body fixedly coupled to the rotor shaft, and a plurality of magnets coupled to the rotor body;
• a stator assembly at least partially received within the rotor body, the stator assembly including
• a stator mount including a stator support portion and a motor support portion,
• a stator core assembly fixedly supported by the stator mount, the stator core assembly including a stator core and an insulator coupled to the stator core, the stator core defining a central bore that receives the rotor shaft and the stator support portion, and
• a plurality of windings that define a plurality of coils supported on the stator core assembly;
• and
• a printed circuit board assembly (PCBA) affixed to the insulator;
• wherein the insulator defines a plurality of standoffs that protrude axially away from the stator core;
• and
• wherein the PCBA includes a circuit board that defines a plurality of through holes configured to receive the plurality of standoffs to secure the PCBA to the insulator.
