Abstract

The invention provides a system for testing motor stall performance experiment, which includes a stall fixture assembly, a driving device and a torque flange; the stall fixture assembly includes a stall base, a brake disc and a torque flange mounting plate, The brake disc is fixedly connected with the torque flange mounting disc, and there are multiple concentrically arranged arc-shaped slots on the brake disc; the brake disc is fixed on the locked-rotor base through multiple bolts and arc-shaped slots; the drive device drives The brake disc rotates; the torque flange mounting disc is fixedly connected with the torque flange. The system for testing motor stall performance experiments described in the present invention solves the shortcoming of requiring a dynamometer for stall testing. The stall torque characteristics at any point can be efficiently tested through the stall test fixture, and the stepper motor is used to cooperate with the stall test. The rotating test fixture avoids the complexity of the disassembly and assembly of the experimental motor; it can avoid damage to the dynamometer, and has the advantages of convenient disassembly and assembly, high degree of automation, and the ability to efficiently complete the laboratory's requirements for the motor stall test experiment.

Description

technical field [0001] The invention belongs to the technical field of motor detection, and in particular relates to a system for testing motor stall performance experiments. Background technique [0002] The drive motor system is the core component of the power output of electric vehicles, and it is a mandatory inspection item for new vehicle product announcements. It is carried out according to GB / T18488-2006 "Electric Vehicle Motors and Their Controllers", "Stall Torque and Stall Current" It is one of the test contents, which is used to investigate the ability of electric vehicles to start on flat ground or slopes and the system protection function. In addition, the locked-rotor test can also be used to test the "static torque ripple" of the motor system. By adjusting the angle of the output shaft, the range of torque fluctuations at different output angles of the motor at rest can be tested, and the motor can be judged by the size of the torque ripple. And the pros and ...
