Abstract
A stage hoist motor assembly includes a first electric motor including a first brake and a second electric motor including a second brake. The first electric motor and the second electric motor are stacked one atop the other within a common plane. A cable winch is rotatable about a winch axis and includes a cable winch shaft that is driven by the first and second electric motors through respective ones of a first drive coupling and a second drive coupling. A width of the motors is less than a width of the winch. Moreover, the motors are stacked one atop the other within a common plane to provide a compact foot print that is favorable to use in performance venue environments.

A stage hoist motor assembly comprising:
- a first electric motor including a first brake;
- a second brake;
- a cable winch that is rotatable about a winch axis;
- a first drive coupling between the first electric motor and the cable winch;
- and
- a second drive coupling between the second brake and the cable winch, wherein the first electric motor and the second brake are both centered along a common plane disposed transverse to the winch axis, wherein the assembly is of a longitudinal length that is between 3¾ and 4¼ times a greatest width of the assembly in a direction parallel to the winch axis.
