Hub Motor System and Characteristic Analysis

2016-05-31 13:57

The in-wheel motor system is usually called the in-wheel motor, and some researchers call it the wheel motor, electric wheel or wheel motor. The English name is mostly "in-wheel motor", and it is also called "wheel direct drive motors" and "wheel motor. In fact, the above terms are strictly inaccurate. The "hub motor, wheel motor and wheel motor" all focus on the motor, while the "electric wheel" focuses on the wheel. From the system point of view, we should refer to the integrated multi-functional system formed by the tight integration of the drive motor and the wheel, that is, the "integrated motor and wheel system". Analysis of the characteristics of the in-wheel motor system Generally, electric vehicles use a centralized motor-driven power system structure. This type of structure has the following advantages:

(1) The integrated structure of the motor and the deceleration mechanism, and even the controller can be used, and the structure is compact, which is easy to deal with the problems of motor cooling, vibration isolation and electromagnetic interference;

(2) Part of the transmission device of the internal combustion engine power vehicle can be used and arranged in the original engine compartment, with good inheritance;

(3) The general layout of the vehicle is close to the internal combustion engine, and the front compartment thermal management, sound insulation treatment and collision safety are close to or easy to handle with the original vehicle.

The disadvantages are:

(1) The transmission chain is long and the transmission efficiency is low;

(2) It is usually required to use high-speed and high-power motors, which require high motor performance.

Decentralized motor drives have the following advantages over centralized motor drives:

(1) Canceling the mechanical differential device is conducive to reducing the quality of the power system, improving transmission efficiency, and reducing transmission noise

(2) Reduce the performance requirements of the motor, and have the characteristics of high redundancy and reliability;

(3) It is conducive to the optimization of the overall layout of the vehicle and the matching optimization of the dynamic performance of the vehicle;

(4) The electronic differential control technology is used to realize the movement of the inner and outer wheels at different speeds when turning, and the accuracy is higher.
