5、g Fan Motor Mounting RATIONALE This document is intended to encourage commonization. The present state is that this attachment varies with the Original Equipment Manufacturer (OEM) and Supplier. In general, the variation is arbitrary, adding cost but not value. 1. SCOPE This SAE Recommended Practice

6、 is applicable to Electric Drive Cooling Fan Assemblies used in Light Duty vehicle cooling systems (typically, passenger cars and light duty trucks). This document outlines the Electric Drive Cooling Fan Motor Mounting interface characteristics such that a common standard is possible. 1.1 Purpose Th

7、is Recommended Practice is intended to document the recommended set of standard mounting interface dimensions for attachment of electric cooling fan motor to fan shroud. 2.

DEFINITION The Recommended Practice provides for three families of bolt circle diameters, essentially a small, medium and large. All of the bolt circ

9、les have the attaching holes spaced at 120 degree intervals and all of the attaching holes are the same diameter. From a general application standpoint, the intent of defining three families promotes the optimum standardization, while recognizing that there still is need to accommodate a broad range

10、 of application. By way of example, the SMALL bolt circle would typically apply to low-power 2-pole motors used in small car cooling applications or for supplemental or “boost” fans, typically at a power level less than 150 W. The MEDIUM bolt circle would accommodate a mainstream medium power 4-pole

11、 motor typically covering a range of 150 to 500 W. The LARGE bolt circle would apply to very high power 4-pole brush type motors or their brushless equivalent exceeding 500 W. There may be argument that there are applications where an attachment scheme using more than three bolts and having spacing

12、different than equal as well as encompassing diameters different from what is recommended here. However, the intent of this Recommended Practice which involved input from the various suppliers was to create a simple basis for communization that would apply to 85% of both the Supplier and OEM users.
