The MPM motors had a trapezoidal option and a sinusoidal option. The trapezoidal option was discontinued as these are redundant and almost all newer digital drives sinusoidally commutate the motors.
There is no difference between the sine option and the trap option, just the part number and the way the current units printed on the side of the motor. They are the same resistance and inductance; it is only a unit conversion between Amp trapezoidal (six-state current) to Amp peak of sine wave. Further details on the calculations for the differences are listed in this document: http://www.parkermotion.com/new_ulm/appnotes/SINETRAP.zip

Note the MPM40 and MPM72 frame sizes are no longer available.
If you have spares, the part number on the right can be used as replacements.
For new replacements, we'd recommend contacting your local Parker Automation Technology Center (ATC) distributor to discuss the machine requirements and investigating the SM16 or BE16 as potential replacement for the MPM40, or the N070 as potential replacement for the MPM72.
