Abstract

The invention discloses a speed limiting device of a controller with a DC brushless electric machine and a speed limiting method. The device comprises a setter, a controller and an electric bike, wherein the electric bike is bidirectionally connected with the controller, and the controller is bidirectionally connected with the setter. The method comprises the steps that a rolling handle is rotated, a setter single chip informs a controller single chip via a serial port to save the corresponding PWM value at the speed as the maximum value, and in the later operation, the controller output PWM is smaller than the saved PWM, i.e. the speed of the electric bike is lower than the set speed so as to realize the speed limiting function. The invention is particularly suitable for electric bike manufacturers, dealers and individuals.

Description

technical field [0001] The invention relates to the technical field of speed limiting of electric bicycles, in particular to a speed limiting device and a speed limiting method provided with a DC brushless motor controller. Background technique [0002] The state stipulates that the speed of electric bicycles cannot exceed 20 kilometers. At the same time, due to considerations of safety and other factors, different users have different requirements for the maximum speed of electric bicycles. The speed of the existing controller has been set before leaving the factory, and due to unmeasurable factors such as the motor, load, and motor wheel diameter, the controller cannot accurately limit the speed, let alone customize it according to user needs. Contents of the invention [0003] The object of the present invention is to overcome the shortcomings of the prior art, and provide a speed limiting device and a speed limiting method for setting a brushless DC motor controller. ...
