International Classification:

H02K 21/24

Abstract:

A modular DC motor includes a stator module having a stator core. The stator core has a ring-shaped base defining an axis and a plurality of stator posts protruding axially outward from the ring shaped based. A plurality of coils are wound around the stator posts. Each stator post extends axially beyond the corresponding coil. A shaft support is radially inward of the stator ring shaped base and is connected to the ring-shaped base. The shaft support is configured to support a rotor shaft relative to the stator core. The stator module is configured to receive one of a plurality of rotor modules. An operation of the modular DC motor is dependent on the physical configuration of the received one of the plurality of rotor modules. Each rotor module in the plurality of rotor modules has a distinct magnetic configuration from each other rotor module in the plurality of rotor modules.

Abstract:

A brushless DC motor (BLDC) includes a stator having a ring-shaped body with multiple stator posts extending axially outward from the ring-shaped body. A plurality of stator windings are each wound about a corresponding one of the stator posts. A rotor support structure is positioned radially inward of the multiple stator posts. A rotor including a shaft is received in the rotor support structure. A first rotor disk is fixed to a first end of the shaft. At least a first set of magnets is disposed about the rotor disk and positioned radially adjacent to the stator posts such that the first set of magnets and the stator windings define a first radial flux flowpath. A second set of magnets positioned relative to the stator posts in one of an axial adjacency or a radial adjacency such that a second flux flowpath is defined.
