The torque/speed curves shown below are actual curves for the green maxon motor (pictured at right) used by students in 2.007. One is a plot of empirical data, and the other was plotted mechanically using a device developed at MIT. Note that the characteristic torque/speed curve for this motor is quite linear.

For this crusher 26 deg. was chosen as the governing angle; about 28 deg. is the conservative maximum for the largest machines of this type. High-Speed Crushers So far, all of the crushers we have been discussing have been of the "low-speed"class; that is, with eccentric speeds ranging between the approximate limits of 100-200 RPM.
