Insert for fan-motor assembly

---

Abstract

---

A fan assembly includes an end bracket which is coupled to a motor assembly. The end bracket includes a circumferential channel which is interrupted by an opening. A fan is provided which includes a plurality of blades. A shroud at least partially encloses the fan and defines a chamber. An insert, which may or may not be an integral part of the end bracket, is received in the chamber and includes a circumferential ramp. The circumferential ramp is configured to provide the chamber with an internal cross-sectional area which varies circumferentially so as to improve airflow efficiency.
