A diagnostic system for a twin propeller drive unit, in particular a diagnostic system for a marine propeller drive unit, the drive unit being a self-balancing drive unit comprising a differential device that distributes a drive torque of a motor between at least two propellers, the diagnostic system comprising a processing circuit, and a processing circuit connected to a speed sensor system connected to the differential device to provide speed data indicative of a rotational speed of the at least one propeller shaft to the processing circuit and a control unit associated with the motor, the control unit providing current data indicative of a motor current drawn by the motor to the processing circuit, a processing circuit monitors the current data and the speed data and classifies a state of the self-balancing propeller drive unit into a predetermined number of states including one or more fault states based on the current data and the speed data, the processing circuitry triggers an action of the diagnostic system in a case where the state of the self-balancing propeller drive unit is classified as a fault state.

    双螺旋桨驱动单元的诊断系统,尤其是一种船用螺旋桨驱动单元的诊断系统,该驱动单元是包括差动装置的自平衡驱动单元,差动装置将电机的驱动扭矩分配在至少两个螺旋桨之间,诊断系统包括处理电路,该处理电路连接到速度传感器系统和与电机相关联的控制单元,该传感器系统连接到差动装置以将指示至少一个螺旋桨轴的旋转速度的速度数据提供到处理电路,控制单元将指示由电机汲取的马达电流的电流数据提供到处理电路,处理电路监测该电流数据和速度数据并基于该电流数据和速度数据将自平衡螺旋桨驱动单元的状态分类成包括一种或多种故障状态的预定数目个状态,处理电路在自平衡螺旋桨驱动单元的状态被分类为故障状态的情形中触发诊断系统的动作。
