bstract: Electric vehicles are becoming increasingly popular due to their environmental benefits and the need to reduce dependency on fossil fuels. Due to their great efficiency, dependability, and low maintenance requirements, BLDC (Brushless DC) motors and PMSM (Permanent Magnet Synchronous motors) are frequently utilized in EVs. For these motors to operate as efficiently and as effectively as possible, control is essential. This study provides an overview of the control strategies utilized for BLDC and PMSM motors in EVs. This study examines and compares the torque ripple, efficiency, and cost of these motors, along with the different control techniques utilized. This review paper highlights the problems and potential in this area while providing a thorough analysis of the current state of the art in the control of BLDC and PMSM motors in EVs.

The current review examines 24 research articles about Odonata Diversity and Habitat, which were previously collected from all over India, and includes an update on their systematic account, sighting period, diagnostic features, measurements, distribution, and perching behavior, conservation status, and threats. If the habitats are saved and safeguarded, this is favorable for their survival.
