Stator Comprehensive Testing System

Stator testing System is a specialized device used to measure the electrical and mechanical properties of a stator to ensure its quality, performance, and reliability before it is used in a motor or generator.

Stator comprehensive testing system typically perform several tests in a single step are following :

DC Resistance Testing : Detects permanent internal short circuits, open circuits or incorrect coil turns.

AC withstanding Voltage Testing : Verify that the stator generates AC voltage within the specified range when the engine is running.

Insulation Resistance Test : Assess the integrity of the insulation between the coils and ground, or between the coils themselves.

Surge Test : Detects turn-to-turn shorts between turns of the same coil, which other tests might not detect.

Rotation Test : in stator testing equipment is "essential," especially in three-phase stators or motors that need to rotate in a predetermined direction.

Partial Discharge (PD) Test : Identify latent defects in insulation that can lead to failure over time, particularly in inverter-controlled motors.

Inductance & Capacitance (L/C): Measures inductance and capacitance to ensure that the coil winding is symmetrical across all phases.

Tessio's designing automation features to support the customers included:

• It can integrate more than 5 test functions and complete all tests with one wiring connection.
• The system can support up to 16 channels, meeting the needs of testing multiple windings, multiple attachments, and multiple taps of the motor.
• The extendable resistance measurement range is 0.001mΩ ~ 20.000kΩ the upper limit of the insulation testing range reaches 50GΩ.
• The low inductance characteristics of the new energy main drive motor, special constant voltage, impact and oscillation technologies are developed, and the interturn detection ability is many times higher than that of traditional technology.
• High The accuracy of the module can reach up to 1% level, which is the measurement level of the same type of international single-function meter in the United States.
• It has undergone strict working condition tests and millions of tests in complex environments.
• The system supports USB, RS232, LAN, and other interfaces, supports PLC communication, TCP/IP network protocol, etc., which is convenient for data interaction and instrument control and meets the requirements of automatic production line docking.
