Abstract

Magnetic couplings allow the design of full waterproof underwater thrusters. It is possible since magnetic couplings assure contactless mechanical power transmission, which rules out the usage of complicated and unsure mechanical seals that jeopardize underwater vessels by a hull breach. Magnetic couplings have less acoustic operation noise and inherent overload protection, which are interesting features for submarines. Moreover, it can increase the thruster performance since it eliminates the friction inherent to mechanical seals. This performance augmentation is possible when the hull material is not conductive. In this context, a way to calculate , in an unique equation, the motor power to design a new thruster is presented from the task where the drone advances in its maximum speed. Otherwise, the applied method can also be used to know the maximum waited speed from the already defined motors. It can help robots designers in sizing appropriate thruster motors for more efficient new underwater drones.
一种基于任务的水下无人机防水推力器功率计算方法
磁性联轴器允许设计全防水水下推进器。这是可能的,因为磁性联轴器确保了非接触式机械动力传输,这就排除了使用复杂且不确定的机械密封,这些密封会因船体破裂而危及水下船只。磁联轴器具有工作噪声小、固有过载保护等优点,是潜艇的一大特点。此外,它可以提高推进器的性能,因为它消除了机械密封固有的摩擦。当船体材料不导电时,这种性能增强是可能的。在这种情况下,提出了一种计算方法,在一个独特的方程中,从无人机以最大速度前进的任务中,提出了一种设计新推进器的电机功率的方法。否则,应用的方法也可以用来知道从已定义的电机的最大等待速度。它可以帮助机器人设计师为更高效的新型水下无人机设计合适的推进器马达。
