the elevator doors, Yoshikawa locates the motor 9a at the top of
the frame member 2 which is connected to the front of the
elevator.
Turning to Aulanko, we find that the reference (col. 1,
lines 4-7) is directed to “elevator machinery comprising a motor,
a traction sheave designed to move the elevator ropes, a bearing,
a shaft, a stator provided with a winding, and a rotating disc-
shaped rotor.” It is disclosed (col. 2, lines 1-6) that:
The invention is characterized by elevator machinery
comprising a motor provided with a frame plate, at
least one bearing, a shaft, at least one stator with
a winding and a rotating disc-shaped rotor with an
air gap between them. The elevator machinery also
has a tracking sheave provided with rope grooves
and designed to move the elevator ropes.
As shown in figure 4, the motor (rotor 17, stator 14 and shaft
13) is integrated onto sheaves 18a, 18b, which hold ropes 2. It
is further disclosed (col. 5, lines 5-10) that “[a]s compared
with motors constructed according to previously known technology,
the elevator machinery (and motor) of the invention is very flat.
It can therefore be installed in many places in an elevator
system where previously known motors are difficult, even
impossible to install without an increased space requirement.”
Although Aulanko is directed to the hoisting motor of the
elevator, and not to a door motor, we find from the above
