Características del producto

A comprehensive test system specially used for performance verification, efficiency analysis and fault diagnosis of synchronous motors or generators.

Different from asynchronous motor testing, synchronous motor testing focuses on excitation control, power factor regulation, synchronous stability and other characteristics.

Test Items

No-load Characteristics: Measures no-load loss, excitation current-terminal voltage curve (generator open-circuit characteristic).

Load Characteristics: Efficiency-map drawing, power factor regulation capability (capacitive/inductive).

Sudden Load Application/Removal: Dynamic speed regulation rate, recovery time (assesses speed regulation system response).

Loss of Synchronism and Resynchronization: Artificially creates loss of synchronism, verifies protection device action and resynchronization strategy.

Short-circuit Characteristics: Three-phase short-circuit current test (verifies transient impact resistance).

Shaft Voltage/Current: Detects bearing electric corrosion risk (focus on high-frequency inverter power supply).
