RPM of variable speed DC Motors
After some web surfing, with HP being the same on a permanent magnet
DC motor, is a lower RPM for the given HP better than a higher RPM for the same HP? Motor A: 1HP, 90V, 2500 RPM, 10.7A 4.28A per 1,000 RPM Motor B: 1HP, 90V, 1750 RPM, 9.2A 5.26A per 1,000 RPM Since I'm a recovering college graduate, does this mean more kick per RPM by the lower speed drive? |
