Motor Integrated Test System

Motor Testing Types

In the production and repair of electric motors, testing is primarily divided into two stages: semi-finished product testing and finished product testing.

One, semi-finished product testing The semi-finished product tests primarily focus on the components or assemblies of motors. This includes tests such as the inter-turn withstand voltage test for windings, the three-phase current balance test for stator three-phase windings, the measurement of insulation resistance between windings and the housing, as well as the dielectric strength test (commonly known as the withstand voltage test), and inspection tests for the rotor.

Section Two: Product Testing Final product testing involves performance tests on the motor after it is assembled into a complete unit. Depending on the requirements, final product testing is divided into two main categories: type tests and inspection tests.

Type Testing

Please provide the Chinese content you would like to have translated into American English.GB755-2008In "Rotating Electric Machine Standard Ratings and Performance," the definition of type testing is: Tests conducted on one or more motors manufactured according to a specific design to demonstrate that the design meets certain standards. In reality, type testing refers to tests that can accurately obtain the performance parameters of the motor being tested. Depending on the requirements, the tests can include all items specified in the standards or relevant technical requirements, or only some of them.

In accordance with national standards, type tests should be conducted on motor manufacturing units under the following circumstances.

（1Newly designed and trial-manufactured products. This type of test is also known as"Certification Test"。

（2After certification and standardization, the product has entered small-scale production.

（3Products where changes in design or craftsmanship are sufficient to cause certain characteristics and parameters of the motor to vary.

（4Products exhibiting unacceptably deviant test results from previous type tests.

（5Routine sampling after the self-forming product goes into production.

Inspection and Testing

Inspection and testing are generally referred to as factory tests. This refers to the partial performance checks conducted on each assembled motor during the mass production of a specific type of motor. These checks include insulation resistance measurement, power frequency withstand tests, inter-turn withstand tests, direct resistance measurement, no-load tests, blocked-rotor tests, noise, vibration, and more.
