eDC are DC motor, where the roles of the stator and rotor are reversed. the eDC motor features a rotor that carries the magnetic field while the stationary stator houses the armature windings. This configuration allows the stator generate a rotating magnetic field through external commutator similar to a conventional DC motor but with significant improvements in modularity and maintainability.

a solid state commutator,
Uses silicon half-bridge circuits and a microcontroller to detect the rotor’s magnetic field angular position.
Electronically simulates the function of a mechanical commutator to commutating the stator’s multiphase windings.

1. eDC motors Closed-loop Delta Winding vs BLDC motors Open-loop Star Winding.
transient current from closed-loop winding flow to low potential, help building up next current flow on commutation schedule,
Star winding generate transient current, increase stress on the controller’s body diode, generate heat on controller

Star winding generate transient current, increase stress on the controller’s body diode, generate heat on controller
2. BLDC commutation on Delta winding generate in slot current cancelation, reduce motor power density.
3. BLDC topology have 4x coil resistance vs eDC on same winding gauge; less heat generated from eDC, eDC have higher motor power density,
4. BLDC have 2X back emf vs eDC require 2x electric potential.
