What Types Of Electric Outboard Motors Are There?

The core components of an electric outboard motor are the motor, the battery, and the control circuit that controls the speed of the motor, and the others are the casing, connecting body, suspension device, and other value-added components such as GPS chips, battery management circuits, and so on. However, what types of motors are there? In this regard, the relevant person from the outboard motor manufacturer said:
Undermounted motor, as the name implies, the motor is placed at the bottom of the outboard motor, and the output shaft of the motor directly drives the propeller shaft to rotate. The commonly used motor is a DC brushless motor with a high energy conversion rate; the converted kinetic energy is directly transmitted to the propeller, and the energy loss is low; the intermediate connector does not involve power transmission, and the shape design is completely considered from the perspective of fluid mechanics, which can be greatly reduced. Water resistance coefficient, so the energy utilization rate of this structure is high. The motor rotor and shaft system are rotating parts. The whole outboard motor has simple structure, low failure rate and high reliability.
The motor is mounted on top, and the motor is placed on the top of the outboard motor. The kinetic energy output of the motor is transmitted to the propeller through the transmission shaft in the gearbox. The structure and design of the gearbox are not fundamentally different from traditional fuel outboards. The advantage of this design is that the upper motor is less limited by space, and the volume can be relatively large, which is suitable for outboard motors with higher horsepower.
