For some applications a series motor is the best choice while a sepex motor is better for other applications. In very general terms, a sepex motor won't produce as much low end torque as a series motor and a series motor won't produce as high of RPM for a given load and voltage applied as a sepex motor, but there is a huge overlap between the two extremes where the both do well. |
Well, I like acceleration at least as well as overall top speed. Do you by any chance have 0 RPM torque figures for each motor?
