Abstract

The invention belongs to the field of electric vehicles, particularly relates to a fatigue tester for a motor of an electric vehicle. The fatigue tester for the motor of the electric vehicle comprises a pedestal for supporting the tester; and the fatigue tester is characterized in that two ends of an upper surface of the pedestal are provided with supporting seats, the left supporting seat supports one end of the to-be-tested motor, the right supporting seat is connected with a rotating shaft of a direct current generator, the to-be-tested motor and the direct current generator are interconnected through a coupler, the pedestal is internally provided with a driving power supply for driving the to-be-tested motor to work, and an output end of the direct current motor is connected with a load through two leads. The fatigue tester has the following benefits that: the fatigue tester for the motor of the bicycle makes the test convenient and flexible, and the fatigue tester for the motor of the bicycle has simple structure and low cost, so that manufacturing difficulty is reduced, mass production is convenient, energy consumption is reduced, and test cost is reduced effectively.

Description

technical field [0001] The invention belongs to the field of electric vehicles, in particular to an electric vehicle motor fatigue testing machine. Background technique [0002] Electric bicycle production is an industry that has developed rapidly recently. Because electric bicycles are easy to use, light and labor-saving to ride, and do not pollute the environment, they belong to motor vehicles. To ensure safe use, electric vehicles must have a lot of quality and safety performance. The standards issued by the state stipulate the performance and inspection methods of various electric bicycles. [0003] The electric bicycle motor fatigue test is an important test item for electric bicycles. It detects the running time of the electric bicycle motor under the condition of rated load continuously until it fails. If it exceeds the specified time, it is qualified. [0004] The existing motor fatigue testing machine is carried out by a general-purpose motor dynamometer. The motor...
