Page Count: 29
scope:

The scope of this standard includes all electric motor driven fan systems that use a specific combination of components as defined below:

1. Fan airflow performance tested in accordance with ANSI/AMCA Standard 210 [1] ANSI/AMCA Standard 230 [2], ANSI/AMCA Standard 260 [3] or ISO Standard 5801 [4] or rated in accordance with AMCA Publication 211 [5].

2. Polyphase induction motors within the scope of EPCA [6], IEC 60034-30-1 [7], or GB 18613 [8]. Other types of motors are explicitly excluded.

3. Pulse-width modulated variable frequency drives (VFDs). 4. Mechanical power transmissions that use V-belts, synchronous belts, or flexible couplings.

Purpose

This standard provides a method to estimate the input power and overall efficiency of an extended fan system.

An extended fan system is composed of a fan and an electric motor but may also include a transmission and a motor controller. While direct measurement of fan system performance is preferred, the large number of fan system configurations often makes testing impractical. This standard offers a standardized method to estimate fan system performance by modeling commonly used components. Calculations reported in accordance with this standard offers fan users a tool to compare alternative fan system configurations in a consistent and uniform manner.

This document does not provide selection guidance. Users must assure that selected components have sufficient capacity and are configured to produce the desired results.
