Problems solved by technology

However, no matter which method is adopted, the automation level of stall temperature rise measurement in most motor enterprises in my country is relatively low at present. Generally, separate parts are used to form an experimental system, which is completed by manual operation, manual recording, and human monitoring. In addition, the measurement equipment is not suitable for carrying. Impossible to realize on-the-spot measurement at the motor application site

[0033] System operation: "system start and stop", "real-time data browsing", "test data query", "test data deletion".

[0034] Curve browsing: "real-time curve", "historical curve".

[0035] Item inspection: "Public Items", ...

Embodiment 3

[0039] Embodiment three, see image 3 As shown, this embodiment is a test flow chart of an embodiment of a portable motor stall temperature measuring device. The test steps are as follows: Step 1: Select the test motor and set the motor in a locked-rotor state through the mechanical fixture, and then connect the J-type thermocouple in the experimental motor to the connection module (the total number of temperature measurement points of all motors shall not exceed 56);

[0040] The second step is to power on the system, start the test device, and conduct the motor stall temperature experiment according to the test process: (1) Fill in the task list, that is, the entrusted test order number, and the specific parameters are shown in Figure 4 of the attached drawing. (2) Then assign test channels. First, select "Order Number" in the list box on the left column, and then set the time interval in the "Collection Interval Settings" group box on the right, and set the channel number ...

Abstract

The invention discloses a portable lock-rotor temperature measuring device of a motor. The method comprises a monitoring module, a communication module, a temperature measuring module, a portable box module and a wiring module. The portable temperature measuring device has the functions of automatic testing, automatic recording, automatic analysis and automatic control and the testing difficulties of the conventional motor locked-rotor test using separated parts for testing, such as manual operation and recording and human monitoring, are solved; in addition, the device is small in size and easy to carry, and the problems that the conventional device is not easy to carry and can not be used for on-site measurement on a motor application site are solved. By adoption of the portable lock-rotor temperature measuring device designed by the invention, the temperature measuring test can be carried out on the lock rotor of various motors, and the blank in the field is filled.

Description

technical field [0001] The invention relates to a motor temperature measuring device, in particular to a portable motor locked-rotor temperature measuring device. Background technique [0002] In order to ensure the quality of the products, the motor manufacturers must conduct several tests such as life, high temperature, rain, salt spray, and stalled rotor to test the various performances of the motor before the motor leaves the factory. Keep the motor in a stalled state, measure the temperature rise characteristics of the motor, and use it to judge the performance of the motor. Temperature rise is the temperature difference between the motor and the environment, which marks the degree of heat generation of the motor. During operation, if the temperature rise of the motor suddenly increases, it means that the motor is faulty or the load is too heavy. Temperature rise is an important index in motor design and operation. There are three main methods to measure temperature ri...
