An electrically driven wheel for a tracked vehicle which includes a driving track wheel with built in cogs and a brushless DC motor having a mounting shaft to connect the wheels to the tracked vehicle. The brushless DC motor is coupled within the driving track wheel to develop rotational torque for rotating the driving track wheel and includes a drum, a bank of pole assemblies connected between the drum and the stationary mounting shaft, and electrical wiring for energizing the bank of pole assemblies. In an embodiment, the brushless DC motor includes permanent magnet high multiple pole motors. The electrically driven wheels are part of a drive system for the tracked vehicle. The drive system includes a track module frame, at least two flexible tracks coupled with the electrically driven track wheels, and a controller for controlling the electrically driven track wheels in response to a driver command.
