Abstract

The invention discloses an instrument motor running-in ageing test device and method. The device comprises a driving signal generating unit, a keyboard, a display unit, a signal allocation unit, ten motor driving units and ten motor test removable plugboards. The method disclosed by the invention comprises the following steps: the driving signal generating unit generates driving signals used for driving an instrument motor to rotate, the driving signals are respectively sent to the motor driving units by virtue of the signal allocation unit, the motor driving units carry out power amplification on the signals, and a motor to be run in and aged is driven by virtue of the motor test removable plugboards. The test device disclosed by the invention has capability of carrying out running-in ageing test on one thousand instrument motors and also has the advantages of low equipment cost, simple structure, convenience in maintenance and the like.

Description

technical field [0001] The invention relates to a detection device and a test method, in particular to a running-in aging detection device of an instrument motor. Background technique [0002] Instrument motors are developed and designed for automotive dashboards and other indicating devices. The motor is directly driven by the driving signal to drive the pointer to rotate to realize the display of any parameter. Values ​​are accurately represented in an analog fashion without the need for analog-to-digital conversion. There is a set of 1:180 reduction gear system inside this meter motor. The instrument motor can generally run at a frequency of up to 600Hz, that is, the output shaft can rotate at a speed of up to 600° / s, so the motor can meet the needs of many indicator applications. [0003] Due to the reduction gear system inside the motor, in the initial stage of use of the gear system, the meshing between the gears is not smooth due to the surface roughness of the mat...
