Abstract

The invention discloses a device for precisely positioning a working gear of a motor. The device includes a gear cover, an output shaft and a final gear, wherein the final fear is fixedly connected with one end of the output shaft; the other end of the output shaft extends to the outer side of the gear cover; the output shaft can be matched with the gear cover in a rotating manner through bearings; a rotating speed inducing magnetic steel is mounted on the side surface of the top of the final gear; a Hall rotating speed sensor is fixedly mounted on the inner side of the gear cover, corresponding to the rotating speed inducing magnetic steel in position. The device for precisely positioning the working gear of the motor, provided by the invention can timely and precisely measure the actual running speed of an electrically-propelled bicycle, thereby precisely positioning the working gear of the motor, enables the motor to always work efficiently, and is strong in power and power-saving; and in addition, the device has the advantages of being low in manufacturing cost and convenient to mount.

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...
