An Efficient BLDC Motor Drive for Electric Boat

Nowadays peoples are more attracted to tourism, among them rural tourism in backwaters and navigable canals are popular. Due to rising temperatures and with the exhaustion of fossil fuels, a new market for Electric Vehicles (EVs) in marine applications has emerged. Because of its great efficiency, high power density, and nearly no maintenance requirements, Brushless DC (BLDC) motors and their drives are gaining popularity every day. In this paper, BLDC drive with Maximum Torque per Ampere (MTPA) controller for marine application are modeled and analysed. MTPA approach is used to determine the minimum operating current that can produce maximum torque.
