Abstract

The utility model belongs to the field of electric bicycles, and particularly relates to a fatigue tester for a motor of an electric bicycle. The fatigue tester comprises a base for supporting the tester and is characterized in that supporting seats are arranged at two ends of the upper surface of the base, wherein the left supporting seat supports one end of a rotating shaft of the motor to be tested; the right supporting seat supports a rotating shaft of a direct current generator; the motor to be tested is connected with the direct current generator through a coupling; a driving power supply for driving the motor to be tested to work is arranged in the base; and the output end of the direct current generator is connected with a load through two leads. The utility model has the advantages that the fatigue tester for the motor of an electric bicycle tests the electric bicycle conveniently and flexibly, has a simple structure and is low in cost; the manufacturing difficulty is reduced, and batch production is facilitated; and furthermore, energy consumption is reduced, and the test cost is effectively reduced.

Description

The electric vehicle motor fatigue tester

Technical field

The utility model belongs to electric automobiles, particularly a kind of electric vehicle motor fatigue tester.

Background technology

An industry of nearest develop rapidly when electric bicycle is produced, because electric bicycle is easy to use, it is brisk laborsaving to ride; Free from environmental pollution again, belong to motor vehicle, use formality convenient; Receive liking very much of boss's surname, be widely used in common people's trip, for the use that ensures safety; Electric motor car must have a lot of quality and security performance, and the standard of country promulgation has been stipulated the performance and the method for inspection of various electric bicycles in the related standards.

The electric bicycle motor testing fatigue is the important tests project of electric bicycle, on detect electric bicycle motor continuous cloud under the situation of nominal load and be drilled into the working time that produces fault, exceed schedule time to qualified.

The prior motor fatigue tester is that general motor dynamometer machine carries out, and motor dynamometer machine function is a lot, complex structure; Its price is also relatively more expensive; The duration of runs of electric bicycle motor testing fatigue is extremely long, need take the motor dynamometer for a long time, and therefore the cost of test is high; Waste is big, does not meet the requirement of test.

Summary of the invention

To above-mentioned technical matters, the utility model provides a kind of ability simple in structure, easy to manufacture, cheap, and testing cost is low, has effectively reduced business burden.

The technical scheme that realizes the utility model is following:

The electric vehicle motor fatigue tester; It comprises the support that is used for a support tester; It is characterized in that: the two ends of the upper surface of described support are provided with supporting base; The end that the left side supporting base is treated the rotating shaft of measured motor supports, and the right side supporting base connects the rotating shaft of Dyn., and described treating connects through a shaft coupling between measured motor and the Dyn.; Described base set inside has the driving power that drives machine operation to be measured, and the output terminal of said Dyn. is connected with a load through two leads.

The beneficial effect of the utility model is that the electric bicycle motor fatigue tester makes test convenient, flexibly; The electric bicycle motor fatigue tester is simple in structure, and cost is low, has reduced manufacture difficulty; Be convenient to large batch of production, reduced, can effectively reduce testing cost with energy consumption.
