Abstract

The invention relates to the field of outboard engines, in particular to a direct-drive electric outboard engine. The direct-drive electric outboard engine is used for solving the problem that an existing outboard engine cannot balance the rotation speed and torque requirements of different types of vessels. The direct-drive electric outboard engine includes an outer rotor mechanism and a stator mechanism. The outer rotor mechanism includes an outer rotor and an impeller, and the outer rotor is disposed outside the stator mechanism in a sleeving mode. The impeller is located outside the outerrotor. First of all, the invention belongs to the outboard engine of the outer rotor, and the output torque is larger and the load capacity is higher. Secondly, according to the design mode of the outer rotor mechanism of the direct-drive electric outboard engine, the transmission part between an impeller and a motor in an existing outboard engine structure is eliminated, so that the rotation speed is higher and the speed regulation range is wider, and the defect of the low rotation speed of an ordinary outer rotor outboard engine is alleviated.

Description

technical field [0001] The invention relates to the field of outboard motors, in particular to a direct-drive electric outboard motor. Background technique [0002] With the continuous improvement of consumers' living standards, the demand for outboard motors continues to increase. An outboard motor refers to a propulsion engine installed on the outside of the hull or ship, usually suspended on the outside of the transom, also known as an outboard motor. Outboard motors are highly integrated and easy to install and purchase. They are the first choice for personal leisure and entertainment boats, and are also widely used in commercial operations and government law enforcement. The existing direct-drive outboard motors on the market usually use a traditional inner rotor motor or a motor with a gearbox to drive the overall propeller. [0003] This structure mainly has the following defects: [0004] First, the inner rotor motor usually outputs high speed and low torque. If t...
