Auto Sizing

An initial value for several parameters related to the size of the machine based on:

• torque per unit volume
• rated current density

Winding Layout

• Automatic winding layout feature
• Supports several wire sizing methods
• Relevant factors (winding factor, fill factor, back emf, etc) are automatically calculated

Rapid and Accurate Results

• Results based on machine with ideal or non-ideal drives
• Users control the level of refinement (accuracy vs time)
• Lumped Parameter analysis also supported for use in equivalent circuits
