Abstract

An elevator system includes an elevator car (14) to travel in a hoistway; and a linear propulsion system to impart force to the elevator car; the linear propulsion system including: a secondary portion (18) mounted to the elevator car; and a primary portion (16) mounted in the hoistway; the primary portion including: a mounting assembly (50) including: a mounting panel (52); a plurality of coils (51) mounted to the mounting panel; and a cover (70) secured to the mounting panel, the cover and mounting panel enclosing the coils.

Claims

1. An elevator system, comprising:

an elevator car to travel in a hoistway; and

a linear propulsion system to impart force to the elevator car;

the linear propulsion system including;

a secondary portion mounted to the elevator car; and

a primary portion mounted in the hoistway;

the primary portion including;

a mounting assembly including;

a mounting panel;

a plurality of coils mounted to the mounting panel; and

a cover secured to the mounting panel, the cover and mounting panel enclosing the coils.

2. The elevator system of claim 1, wherein:

the mounting assembly is modular assembly, a plurality of mounting assemblies forming the primary portion.

3. The elevator system of claim 1, wherein:

the secondary portion includes two secondary portions, the primary portion being positioned between the two secondary portions.

4. The elevator system of claim 1, wherein:

the secondary portion includes two secondary portions, the primary portion includes two primary portions, the two primary portions being positioned between the two secondary portions.

5. The elevator system of claim 1, wherein:
