The utility model relates to an electric closed type car starting motor test platform, and relates to a car starting motor test platform. The utility model aims at the defects that the existing car starting motor test platform adopts the loading mode of a magnetic powder brake, a loading system is easy to generate heat, the precision is low, the range is narrow, the loading system is not stable, etc., and the utility model provides an electric closed type car starting motor test platform which has simple structure and converts mechanical energy into electrical energy. An output positive pole (9) and an output negative pole (8) of a permanent magnetism servo motor (7) are respectively connected with an inverter input positive pole (11) and an inverter input negative pole (10) of an active inverter (13), and an output positive pole and an output negative pole are connected with a three-phase electric network (12).
Description
One, technical field
The utility model relates to the automobile starting motor testing table, especially a kind of electrical-closed automobile starting motor testing table.
Two, technical background
For various motor test equipment, loading method and control system thereof are the keys of testing equipment, and it has determined the main performance of testing table substantially.In automobile starting motor testing table in the past, the general load mode that adopts magnetic powder brake, the energy that its principal feature is produced when being motor test becomes thermal energy consumption by charger and falls, but because the automobile starting motor moment of torsion is big, can cause the loading system heating serious during follow-on test, thereby can't adapt to the requirement of actual production test beat.And loading accuracy is lower, narrow range, charger volume are big, needs shortcomings such as additional cooling or energy-dissipating device.
Three, summary of the invention
Provide a kind of simple in structure during the purpose of this utility model, transform the electrical-closed automobile starting motor testing table of electric energy by mechanical energy.The technical scheme that the purpose of this utility model adopted is, output shaft by the analog power that has electric power connection line, speed reduction unit links to each other with the square speed probe input shaft of walking around with shaft coupling, the torque rotary speed sensor output shaft with the axle of shaft coupling and permanent-magnet servo motor link to each other, active inverter forms, the output cathode of its permanent-magnet servo motor and output negative pole import with inverter with the inverter input of active inverter is anodal that negative pole links to each other, output links to each other with three phase network respectively.
The utility model in use, tested actuating motor is connected analog power, connect upper reducer on the actuating motor axle, after dragging rotation, permanent-magnet servo motor is in generating state, the mechanical energy that produces when permanent-magnet servo motor can be tested automobile starting motor changes into electric energy, and loading control is an active inverter, can be with this electric energy inversion feedback grid.
The utlity model has simple and compact for structurely, fabrication and installation are convenient, and the load torque size of permanent-magnet servo motor is not subjected to that the influence of motor speed, reaction are fast, highly sensitive, wide ranges, good stability, saves characteristics such as electric energy.
Four, description of drawings
Further specify the utility model below in conjunction with accompanying drawing.
Accompanying drawing is the utility model structural representation.
Among the figure: 1-analog power 2-electric power connection line 3-actuating motor 4-speed reduction unit.5-torque rotary speed sensor 6-shaft coupling 7-permanent-magnet servo motor 8-output negative pole 9-output cathode 10-inverter input negative pole 11-inverter is imported anodal 12-three phase network 13-active inverter
Five, embodiment
As shown in drawings, the electric power connection line 2 that has analog power 1 connects actuating motor 3, the input end of the axle connection reducer 4 of actuating motor 3, the output terminal of speed reduction unit 4 links to each other with square speed probe 5 input shafts of walking around with shaft coupling 6, torque rotary speed sensor 5 output shafts link to each other with the axle of permanent-magnet servo motor 7 with shaft coupling 6, and the output cathode 9 of permanent-magnet servo motor 7 links to each other with inverter input negative pole 10 with the inverter input anodal 11 of active inverter 13 respectively with output negative pole 8, output links to each other with three phase network 12.
