Selections are based on a 1.4 service factor, 5 to 1 speed ratio and various Power Transmission Manufacturers’ catalogs.
5.
These selections are for Narrow V belt sections only. Consult manufacturer for details on conventional V belt sections (A, B, C, D and E), or other
belt types.
6.
“Average Deflected Force is per section 3.3.4.4 of this document and is the force required to deflect the center of a belt 1/64 of the belt span
distance. Tolerance on this force is ±1 lbf for forces
≤
10 lbs, and ±2 lbs for forces >10 lbs as measured utilizing a belt tension gage.
7.
When more than one belt is required the belts must be a matched set (matched for length).
8.
If possible, the lower side of the belt should be the driving side to increase the length of wrap on the sheave).
9.
For belted loads do not exceed 125% of 60 Hz operating RPM.

It is the responsibility of the startup personnel during set up of the
VFD / motor system to properly tune the drive to the motor for the
specific application per the VFD user manual. The correct voltage
boost and volts per hertz settings are application dependent and
unique to each motor design. Failure to connect over temperature
devices (when provided) will void the warranty.
