Coil Modeling
The coils in the stator are modeled as ‘Homogenized Multi-Turn Conductor’ with n0
number of turns
The current in the single phase coil is defined as
Note: sqrt(2) term is included to turn the RMS value of current to
peak value
The ‘Coil Group’ check box is checked to connect the coils in
series and reversed current
direction is used to specify the current in negative direction.

Modeling Approach
Force and Torque Calculation
The force on the rotor is calculated using the in-built ‘Force Calculation’ domain feature.
The force and the resulting torque are calculated by integrating the ‘Maxwell’s Stress
Tensor’ over the exterior boundaries of the rotor.
