Abstract
An electric motor having a snap-together construction without the use of separate fasteners. The construction of the motor removes additive tolerances for a more accurate assembly. The motor is capable of programming and testing after final assembly and can be non-destructively disassembled for repair or modification. The motor is constructed to inhibit the ready entry of water into the motor housing and to limit the effect of any water which manages to enter the housing.
Claims38
An electric motor comprising:
- a stator including a stator core, a winding on the stator core, and a first snap connector element;
- a rotor including a shaft received in the stator core for rotation of the rotor relative to the stator about the longitudinal axis of the shaft;
- a housing adapted to support the stator and rotor, the housing having a second snap connector element formed therein, the first snap connector element being engaged with the second snap connector element for connecting the stator and rotor to the housing;
- the first snap connector element comprising plural legs projecting from the stator, each leg being capable of resilient deflection.
