1. A motor assembly comprising:
- a stator;
a rotor having a rotor shaft and electromagnetically interacting with the stator to be rotated; and
an impeller combined with the rotor shaft,wherein the impeller comprisesan impeller body;
a plurality of wings formed on the outer face of the impeller body for producing air currents by rotation; and
a shaft combiner having a shaft insertion hole through which the rotor shaft is inserted, arranged on the impeller body, and formed for the rotor shaft to be pressed in to enable the impeller and the rotor shaft to operate as one body.
