2、 Solve the problem
|
Conduct partial or complete performance tests on the assembled motor, including type tests and factory tests.
Type test: A test conducted on one or several motors manufactured according to a certain design to demonstrate that the design meets the standards.
Factory test: A test conducted on each motor during manufacturing or after completion to determine whether it meets the standards.
The test items and assessment methods for the repaired motor are generally the same as the factory test during motor production.

2. Software
|
The software can meet the testing requirements of users for various motors and test projects, and draw various parameter characteristic original curves, fit curves, and automatically generate no-load point parameters (current, speed), maximum torque point parameters (voltage, current, speed, efficiency, output power), maximum efficiency point parameters (speed, torque, current, output power), and maximum output power point parameters (speed, torque, current, output power). Report and query function: Multiple curves can be drawn in the same coordinate to meet customers' analysis of product consistency and repeatability.

Third item: Load
For a motor with a reference frequency of 50Hz, adjust the output frequency of the frequency converter to 3 (5) Hz, 15Hz, 30Hz, and 50Hz respectively. Measure the voltage, current, input power, output torque, and speed at each frequency point of the tested motor at 100% rated torque, 110% rated torque, and 80% rated torque. Subsequently, at frequencies of 60Hz, 80Hz, and 100Hz, measure the torque values of the tested motor at each point of nominal power, 110% nominal power, and 80% nominal power (the nominal power at this time should be calculated as torque), and plot the load characteristic curve.
