Embodiment Construction

[0012] The technical solutions of the present invention will be further described below through specific embodiments in conjunction with the accompanying drawings.

[0013] An electric bicycle controller includes: a sine wave driver 1, a motor phase wire 2, a relay 3, an electric door lock 4, a motor 5, a motor phase current sampling inductance 6, and a position sensor 7. The sine wave driver 1 is respectively connected to the motor 5 through the motor phase wire 2 and the position sensor 7. The motor 5 is provided with a three-way switch 8 with three phase wires. The motor phase current sampling inductor 6 is installed on the motor phase wire 2, and the sampling The result is fed back to the sine wave driver 1. One end of the relay 3 is used to connect the electric door lock 4, and the remaining three ends are connected with the three-way switch 8 of the three phase lines of the motor 5.

[0014] The specific operation process is as follows: the sine wave driver 1 transmits ...

Abstract

The invention relates to an electric bicycle controller. The electric bicycle controller comprises a sinusoidal wave actuator, electrical machine phase lines, a relay, an electric door lock, an electrical machine, an electrical machine phase current sampling inductor and a position sensor. The sinusoidal wave actuator is connected with the electrical machine through the electrical machine phase lines and the position sensor, and the electrical machine is internally provided with a three-way switch of three phase lines; the electrical machine phase current sampling inductor is installed on the electrical machine phase lines, and a sampling result is fed back to the sinusoidal wave actuator; one end of the relay is used for connecting the electric door lock, and the other three ends of the relay are connected with the three-way switch of the three phase lines of the electrical machine. The electric bicycle controller can obtain continuous three-phase currents, and noises and shocks generated in the driving process of a bicycle are effectively lowered, so that the convenience and safety of being used by wide electric bicycle users are guaranteed.

Description

technical field [0001] The invention relates to the technical field of electric bicycles, in particular to an electric bicycle controller. Background technique [0002] Electric bicycles driven by electric energy are more and more widely used because of their light shape and no exhaust pollution, and have become the main means of transportation for people in today's society. The driving motor of the existing electric bicycle uses a square wave current, which has the advantages of a simple controller structure and easy generation of waveforms, but at the same time has poor control accuracy, large torque fluctuations, high vehicle driving noise, obvious vehicle vibration, and Various security risks and other shortcomings. Contents of the invention [0003] The object of the present invention is to provide an electric bicycle controller with stable driving, high motor control precision and high safety factor. [0004] In order to achieve the above object, the technical solu...
