providing at said vertical wall a drive motor and traction sheave assembly with a common axis of rotation, and configured so that said drive motor has a substantially flat discoidal stator and rotor configuration, with the axis of rotation of said assembly oriented to intersect the plane of said vertical wall while presenting the traction sheave for rotation in the space co-extensive with said shaft which is defined between the elevator car and said vertical wall;

connecting the hoisting rope with the counterweight and the elevator car through the traction sheave; and

suspending the elevator car on the hoisting rope by passing the hoisting rope beneath the elevator car.

104. The method of claim 103, wherein the elevator car is substantially rectangular in cross-section.

105. The method of claim 103, including the further step of mounting the drive motor on said vertical wall adjacent said guide rail assembly to present the traction sheave for rotation within the space between said vertical wall and the elevator car.

106. The method of claim 105, wherein the elevator car is substantially rectangular in cross-section.

107. The method of claim 103, including the further step of mounting the drive motor on said vertical wall adjacent said guide rail assembly to present the traction sheave for rotation within the space between the vertical wall and the elevator car;

and

configuring the drive motor and vertical wall to contain the former within the latter.

108. The method of claim 107, wherein the elevator car is substantially rectangular in cross-section.

109. The method of claim 107, including the further step of providing the drive motor and traction sheave assembly with a shaft along a common axis of rotation, the shaft having a length no greater than the spacing between the elevator car and the thickness of said vertical wall.

110. The method of claim 109, wherein the elevator car is substantially rectangular in cross-section.

111. The method of claim 103, 105, or 107, including the further step of providing the drive motor and traction sheave assembly with a shaft along a common axis of rotation, the shaft, having a length to accommodate presenting said traction sheave within the space between said vertical wall and the elevator car.

112. The method of claim 111, wherein the elevator car is substantially rectangular in cross-section.

113. A method for configuring the space, occupied by an elevator car and the drive assembly associated therewith, the drive assembly including a drive motor, a traction sheave, a counterweight, a hoisting rope, and a guide assembly, comprising the steps of:

constructing an elevator shaft;

placing the elevator car in said shaft;

providing at least one substantially vertical wall in the shaft, coextensive therewith and spaced from the elevator car;

spacing the at least one vertical wall from the elevator car to the extent required to accommodate the thickness dimension of the counterweight, the guide assembly, and requisite safety distances;

providing on said guide assembly a drive motor and traction sheave assembly with a common axis of rotation and configured so that said drive motor has a substantially flat discoidal configuration and that said traction sheave has a lesser diameter than said drive motor, with said common axis of rotation of said assembly oriented to intersect the plane of said vertical wall while presenting said traction sheave for rotation in the space coextensive with said shaft which is defined between the elevator car and said vertical wall;

connecting the hoisting rope with the counterweight and the elevator car through the traction sheave; and

suspending the elevator car on the hoisting rope by passing the hoisting rope beneath the elevator car.

114. The method of claim 113, wherein the elevator car is substantially rectangular in cross-section.

115. The method of claim 113, wherein the entirety of said drive motor and traction sheave assembly is included in the said space coextensive with said shaft.

116. The method of claim 115, wherein the elevator car is substantially rectangular in cross-section.

118. The method of claim 113, wherein the elevator car is substantially rectangular in cross-section.

117. The method of claim 131, including the step of forming a receiving cavity within the thickness dimension of said vertical wall;

and

wherein at least a portion of said drive motor is extended into the receiving cavity formed in said vertical wall.
