Challenges and Opportunities: The use of DC motors presents a number of challenges, including the need for sophisticated control systems for brushless motors and the demand for maintenance for brushed motors. Despite the fact that DC motors play an essential role in industrial machinery, there are also opportunities that this application presents.
Finally, the motor may run differently when rotating in one direction than the other direction, depending on the connection. Finding the three wiring configurations that enable the motor to turn is the easiest way to determine whether the motor is wired correctly. Compare the motor''s operation in each configuration.
However, the advantage is the same control architecture as explained for the BLDC motor can be adopted for any other motor used for electric vehicle application. References. 1.

There are two types of commonly used DC motors: Brushed motors, and brushless motors (or BLDC motors). As their names imply, DC brushed motors have brushes, which are used to commutate the motor to cause it to spin. Brushless motors replace the mechanical commutation function with electronic control.

In brushless DC (BLDC) motor drive circuits, parasitic inductances on the PCB can often result in the motor phase nodes being driven to a negative voltage for a short period of time during switching. This issue is worse with high-current, low-inductance motors, where the dI/dt during switching can be very high.
