Motor
A motor for a driving device includes: a rotor rotatable around a central axis, a stator facing the rotor, a busbar electrically connected to the stator, a busbar support to hold the busbar, a terminal bar including a first end electrically connected to the busbar, the terminal bar including a connection terminal at a second end and that is to be electrically connected to the driving device, and a seal to be attached to the driving device and located between the busbar and the connection terminal. The seal portion includes a through-hole into which the terminal bar is press-fitted.
1. A motor used for a driving device, the motor comprising:
a rotor that rotates around a central axis;
a stator that faces the rotor;
a busbar that is electrically connected to the stator;
a busbar support that holds the busbar;
a terminal bar including a first end electrically connected to the busbar, the terminal bar including a connection terminal at a second end thereof and to be electrically connected to the driving device; and
a seal to be attached to the driving device and located between the busbar and the connection terminal; wherein
the seal includes a through-hole into which the terminal bar is press-fitted.
2. The motor according to claim 1 , wherein the terminal bar further includes:
a bar-shaped portion located between the busbar and the connection terminal; and
a mold portion that covers a portion of the bar-shaped portion and a portion of the connection terminal while electrically connecting the bar-shaped portion and the connection terminal to each other; wherein
the seal is in contact with an end of the mold portion on a side of the bar-shaped portion.
3. The motor according to claim 1 , wherein the seal includes at least one protrusion extending one turn along an outer peripheral surface of the seal.
4. The motor according to claim 2 , wherein the busbar support includes a tubular portion into which the bar-shaped portion is inserted.
5. The motor according to claim 4 , wherein a gap is located between the tubular portion and the bar-shaped portion.
6. The motor according to claim 4 , wherein the busbar support faces an end of the stator on one side in an axial direction, and the tubular portion extends toward the one side in the axial direction.
7. The motor according to claim 4 , wherein the tubular portion includes a rib on an outer surface thereof, the rib extending in an axial direction.
8. The motor according to claim 4 , wherein
the busbar support includes a plurality of the tubular portions; and
each adjacent pair of the plurality of tubular portions are coupled to each other by a coupler.
9. The motor according to claim 4 , wherein
the busbar support further includes a holder that holds the busbar;
the tubular portion protrudes from the holder; and
the busbar is electrically connected to the bar-shaped portion at a position on a base side of the tubular portion.
