Problems solved by technology

However, for motor manufacturers, this test method is extremely complicated and cumbersome, and its measurement accuracy is difficult to guarantee. Moreover, some motors can only run without load or the no-load current is too large. In these cases, the traditional motor Most of the test methods are inappropriate

Embodiment Construction

[0019] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0020] The invention provides a motor parameter automatic testing system. The system includes an integrated box, a power module, a motor, a current sensor module, an analog-to-digital conversion module, a photoelectric encoder, a DSP control system, a serial port, and a host computer display. The detection method of the system is as follows: connect the current sensor module in series to the motor circuit, and measure the current I passing through the motor a ; The DSP obtains the motor speed n through the photoelectric encoder; obtains the motor armature resistance R through the no-load two-point method a ; With current value I a , the speed n of the motor and the corresponding motor armature winding R a Based on this, establish a corresponding mathematical model to solve other motor parameters through DSP, such as: back electromo...

Abstract

The invention relates to a system for automatically testing motor parameters. The system comprises an integration case, of which the side surfaces are provided with three lead-out interfaces. The first interface sends parameter information subjected to DSP control system processing to a host computer for displaying, the second interface communicates with a photoelectric encoder and a motor, and the third interface serially connects the motor and a current sensor module to a circuit. A digital-analog conversion module converts analog voltage into digital voltage and then sends to the DSP control system, and a switch controls a power supply module to supply power to the whole system. Three interfaces are arranged on the side surfaces of the integration case for conducting data transmission with the motor and the host computer. The system is more concise and easy to use.

Description

technical field [0001] The invention relates to an automatic testing system for motor parameters. Background technique [0002] In recent years, with the rapid development of science and technology and the continuous improvement of industrial level, the supply and demand of motors have increased greatly. Especially with the popularity of household appliances, the output of various small and medium-sized motors has also been greatly increased, and the corresponding industry standards for motor performance have also been improved day by day. The development of science and technology has put forward higher and higher performance and quality indicators for motors, so the accurate testing of motor parameters is even more important. [0003] The traditional motor test is completely manual. When the motor is running under load, various instruments are used to measure the motor's current, torque, speed and other parameters, and then the mechanical characteristics and performance pa...
