MotorWizard & EMS have been very helpful in understanding and exploring various rotor and stator configurations in our design of a Brushless motor. As mechanical engineering undergrads, our understanding of electro-magnetic design was limited, but the software really helped us to work through some of the more complex concepts we were coming across in motor design references. 
In particular, MotorWizard proved to be very easy and intuitive to use and helped us in design studies such as the effect of a 3D printed plastic rotor compared to a traditional silicon steel rotor. Lots of online tutorials provided by EMWorks made EMS approachable after viewing a few of the tutorials. 
The academic and technical support representatives were responsive and helpful in getting us software licenses and setting them up with our institution as well as troubleshooting technical issues we were running into.
