Dynamometer & Mechanical System: A high-dynamic asynchronous or synchronous motor is selected as the dynamometer, equipped with a high-speed drive shaft system and precision, reliable mechanical components.
Frequency Converter: A four-quadrant frequency converter is adopted for dynamic or steady-state control of the dynamometer. It enables control of rotational speed, torque, allowing the dynamometer to operate in either motoring or generating mode.
DC/AC Power Supply: Supply power to the starter to simulate the start condition, generally, the current is large. According to the parameters of tested aerospace starter, the power parameters as follows:
Rated power range: 5kW to 2MW
Current range: 0 to ±2000A
DC voltage range: 12VDC to 1200VDC
AC voltage range:115VAC to 400VAC
Electric load: Absorbs the electrical energy from the generator and simulates the characteristics of the power-consuming equipment. JKT provides resistive load, inductive load, capacitive load, as well as regenerative electronic load.
Power Analyzer & Mobile Cart: A high-precision power analyzer is used to measure parameters such as current, voltage, efficiency and harmonics of the motor and controller. It can also receive torque and speed signals synchronously for calculating the motor’s mechanical efficiency.
MCU Power Supply: Provides an adjustable low-voltage power supply for the motor controller.
Test Object Cooling System: According to different tested objects, there are air-cooling system and hydraulic system. The air-cooling system provides adjustable flow rate air for the tested object. The hydraulic system provides the lubricating and cooling oil for the tested object.
Generally, the maximum temperature of the oil is very high, up to 200℃, the hydraulic system adopts high-temperature resistant hydraulic components such as pumps and valves, and is equipped with temperature and pressure compensation. It can generally operate at 180℃~200℃, while enabling precise pressure or flow control.
Climate Chamber: Provides a simulated operating environment with controllable high/low temperature and humidity for the test objects.
Automated Measurement & Control System: Conducts overall control and condition monitoring of the entire motor test bench.
