A simulated motor ( 300 ) is arranged on the support stand ( 200 ), and the simulated motor ( 300 ) is coaxially arranged with the tested motor ( 100 ) to simulate a load when the tested motor ( 100 ) is in operation, thereby allowing a performance test of the tested motor ( 100 ).
1 . A testing device to test the performance of a tested motor ( 100 ), the testing device comprising:
a support stand ( 200 ), wherein the tested motor ( 100 ) is arranged on the support stand ( 200 );
a simulated motor ( 300 ) arranged on the support stand ( 200 ), and the simulated motor ( 300 ) is coaxially arranged with the tested motor ( 100 ),
wherein the simulated motor ( 300 ) is configured to simulate a load when the tested motor ( 100 ) is driving the simulated motor ( 300 ) to rotate at a first speed.
2 . The testing device according to claim 1 , wherein the simulated motor ( 300 ) is electrically connected to the tested motor ( 100 ), wherein the simulated motor ( 300 ) is configured to generate a current during rotation, and wherein the current supplies power to the tested motor ( 100 ).
3 . The testing device according to claim 1 , further comprising a power supply ( 400 ), the simulated motor ( 300 ) is electrically connected to the power supply ( 400 ), and the power supply ( 400 ) is configured to drive the simulated motor ( 300 ) to rotate at a second speed to simulate the load.
4 . The testing device according to claim 1 , wherein the simulated motor ( 300 ) comprises:
an installation shaft ( 310 ) arranged on the support stand ( 200 );
a stator ( 320 ) sleeved on the installation shaft ( 310 ); and
a rotor ( 330 ) sleeved on the stator ( 320 ),
wherein the rotor ( 330 ) is rotatably connected to the installation shaft ( 310 ).
5 . The testing device according to claim 4 , wherein the simulated motor ( 300 ) further comprises a bearing disposed between the rotor ( 330 ) and the installation shaft ( 310 ).
6 . The testing device according to claim 5 , wherein the rotor ( 330 ) is coaxially connected to the tested motor ( 100 ).
7 . The testing device according to claim 1 further comprising a shaft coupling ( 500 ) arranged between the tested motor ( 100 ) and the simulated motor ( 300 ).
8 . The testing device according to claim 1 further comprising a power supply ( 400 ) electrically connected to the tested motor ( 100 ); a voltage stabilizer ( 600 ) arranged between the power supply ( 400 ) and the tested motor ( 100 ).
9 . The testing device according to claim 1 , wherein the support stand ( 200 ) comprises:
a pedestal ( 210 );
a first support stand ( 220 ) fixedly arranged on the pedestal ( 210 );
wherein the tested motor ( 100 ) is arranged on the first support stand ( 220 );
a second support stand ( 230 ) fixedly arranged on the pedestal ( 210 ); and
wherein the simulated motor ( 300 ) is arranged on the second support stand ( 230 ).
