Description

technical field

[0001] The invention relates to a device, in particular to a device for precisely positioning the working gear of a motor. Background technique

[0002] When an electric bicycle equipped with a variable gear motor is used, the working gear of the motor is obtained by measuring the rotation speed of the motor. When the electric bicycle is driving downhill, the motor may stop rotating, and the electric bicycle will slide down at its own speed, causing the motor to The working gear is incorrect. Contents of the invention

[0003] The problem to be solved by the present invention is to overcome the deficiencies in the background technology and provide a device for precisely positioning the working gear of the motor. This device accurately positions the working gear of the motor by measuring the rotation speed of the final output gear, so that the motor always works at High-efficiency section, so as to achieve strong and power-saving effects, making electric bi...
