Embodiment Construction

[0008] The present invention includes a test bench 1, a variable frequency motor 2, a shaft coupling 3, a speed changer 4, a dynamometer 5, a circular connecting disc 6, a bolt 7, a three-jaw chuck 9, a bracket 10 and a screw 11. 8 in the figure is the tested external rotor generator.

[0009] As shown in the figure: a bracket 10 is set at one end of the test bench 1, a variable frequency motor 2 is set at the other end, a three-jaw chuck 9 is set on the bracket 10, and a speed changer 4 is set between the three-jaw chuck 9 and the frequency conversion motor 2. The input shaft of the speed changer 4 utilizes a coupling 3 to be connected with the output shaft of the variable frequency motor 2, a dynamometer 5 is installed on the output shaft of the speed changer 4, and a circular coupling disc 6 is connected to the end of the output shaft of the speed changer 4; The center of revolution of the three-jaw chuck 9 is concentric with the output shaft of the speed changer 4.
