Description

technical field

[0001] The invention relates to an electric vehicle torque induction measuring motor, in particular to an electric vehicle torque and speed integrated measuring device. Background technique

[0002] In the prior art, most of the sensors of electric bicycles are independent components, such as central shaft type torque, claw type torque, and disk type torque. These split sensors are very complicated in structure and assembly for the whole vehicle, and the installation of each component is very complicated. For different parts of the whole vehicle, this solution affects the cleanliness of the whole vehicle, cumbersome installation, long leakage and long wiring, troublesome after-sales service, and potential safety hazards. Contents of the invention

[0003] The object of the present invention is to provide a torque induction measuring motor for an electric vehicle that simultaneously senses torque and speed.

[0004] The present invention achieves the above ...
