Tricycle driving system with low failure rate

Abstract

The invention discloses a tricycle driving system with low failure rate, which comprises a motor on a tricycle frame and a driver for controlling the motor to drive, the motor comprises an encoder arranged on a motor shaft, and the encoder is in communication connection with the driver. The encoder sends a detected rotor position signal to a driver, and the driver performs sine wave driving control on the motor based on the rotor position signal; and according to the invention, the failure rate is obviously reduced, and the driving precision can be obviously improved.

Description

technical field [0001] The invention belongs to the drive control technology of electric vehicles, and in particular relates to a tricycle drive system with low failure rate. Background technique [0002] Due to its better loading capacity, tricycles have their own specific advantages over two-wheeled vehicles, so they have a greater market application demand. However, the driving technology adopted by the tricycle has been using the traditional motor driving technology, and there is almost no real innovation of the driving technology of the tricycle. Driven by square wave control, among them, the structure of the Hall sensor is prone to damage after being used for a long time in the heat-generating environment of the winding, resulting in a high failure rate of the tricycle. At the same time, the existing control method has poor speed-up performance and motor work efficiency Low cost, high cost. [0003] The applicant also noticed that tricycles usually need to have a goo...

Problems solved by technology

However, the driving technology adopted by the tricycle has been using the traditional motor driving technology, and there has been almost no disclosure of the innovative driving technology of the tricycle. Specifically, the Hall sensor installed on the winding is used to detect the rotor position. Driven by square wave control, among them, the structure of the Hall sensor is prone to damage after being used for a long time in the heat-generating environment of the winding, resulting in a high failure rate of the tricycle. At the same time, the existing control method has poor speed-up performance and motor work efficiency low cost high

[0003] The applicant also noticed that the tricycle usually needs to have better loading capacity, and also has the function of using the two-wheeled vehicle, and its applied load range is very wide. Therefore, when the tricycle is used, due to its corresponding load range And uncertain, so the required tricycle motor needs to have excellent speed-up performance when driving. The existing tricycle drive control scheme has been relatively backward compared with the technological development in recent years.
