Testing system of hybrid power motor and testing method thereof

Abstract

The invention relates to a testing system of a hybrid power motor and a testing method thereof, wherein an engine, a motor and a power assembly of a gear box are assembled on the production line by one time; the power assembly is directed transported to a testing bench; firstly, the calibration of a motor position sensor is conducted; next, the reliability test of the motor is conducted; the testing system is provided with a calibration controller which conducts the calibration to the motor position sensor; the testing system also comprises a direct-current power cabinet, a PC computer, a three-phase converter box and a safety micro-control switch, wherein the phase a, the phase b and the phase c of the motor are connected with the calibration controller by the three-phase converter box; the calibration controller is electrified by the direct-current power cabinet and conducts communication with the PC computer by a CAN wire; the PC computer controls the power cabinet by a communication wire; simultaneously, the power cabinet can be controlled by a safety loop and the safety micro-control switch.

Description

technical field [0001] The invention relates to the field of reliability testing of a hybrid electric motor, in particular to a testing system and a testing method for a hybrid electric motor. Background technique [0002] The reliability test of the hybrid electric motor requires a huge bench and a dynamometer to assist in completing the test. The ISG (integrated starter generator) motor needs a control system, and the dynamometer also needs a control system, which is easy Causes the complexity of the control, and is extremely error-prone. After the reliability test of the ISG motor is completed, it is necessary to transport the powertrain to the production line again for assembly of the gearbox, which is unreasonable for logistics and the production line. [0003] At present, in the existing technology, the relevant technical materials include the patent document with the publication number CN200610054022.1. Its main structure is that after the engine and the ISG motor ar...

AI Technical Summary

Problems solved by technology

The purpose is to solve the problem of how to know whether the motor is damaged during the assembly process after the motor is assembled. If the reliability test is not performed on the motor at this time, the motor may not run after the entire powertrain is assembled, or the motor may not Provide appropriate auxiliary torque, resulting in the reassembly of the front cabin of the hybrid vehicle, wasting manpower and material resources
