Product Features
1. Core Technology:
Unique and precise electric dynamometer control strategy, and the first to propose and verify the core algorithm of electric dynamometer control in China, which greatly improves the system dynamic response and control accuracy;
2. Frontier platform:
The unique feed-forward control theory of electric dynamometer, the control system has a built-in "dynamic analysis algorithm of motion equation"; and on this basis, the "electric inertia simulation system" of electric dynamometer has been developed; the only one in China who has mastered the "electric inertia load simulation system" Technology" and "electric dynamometer follow-up technology" can guarantee to replace the traditional mechanical inertia, and at the same time, can ensure the smooth transition of working conditions, prevent extreme conditions such as transmission overload and impact, and protect the safety of the tested product and the system.
3. Autonomous and controllable:
Take the lead in introducing the "central safety control system" in the measurement and control system:
Integrate timing and dynamic triggering functions, real-time dynamic monitoring of the running status of critical parts in the system, provide multi-level protection strategies such as failure warning, threshold alarm, system linkage, emergency shutdown, etc., to ensure system and product safety.
SSCH120 electric dynamometer has the following significant advantages:
The basic principle of Hydraulic and eddy current dynamometer is to convert the mechanical energy generated by the prime mover into heat energy and take away the heat after cooling by water. The energy emitted by the prime mover cannot be recovered, and energy is also consumed during the conversion process. However, the electric dynamometer can convert the mechanical energy generated by the prime mover into electrical energy and feed it back to the internal grid for use by other equipment.
The loading characteristics of the electric dynamometers are constant torque characteristics from zero speed to rated speed, and constant power characteristics from rated speed to maximum speed, which fully comply with the load characteristics of power machinery. Generally, the hydraulic dynamometer can only be loaded in one direction, while an eddy current dynamometer can be loaded in two directions, it cannot be used as a power back-drag prime mover, while the electric dynamometer can easily realize two-way loading and can be used as a power back-drag prime mover.
Due to the use of accessories that fully comply with national standards, users do not have to rely on the manufacturer for maintenance, and can completely carry out daily maintenance by themselves, even when it is necessary to replace the host and sensors. The electric dynamometer is the most ideal replacement product for the technological transformation of enterprise testing equipment due to its simple structure and maintenance-free, in addition to its excellent speed control performance, it also has a significant energy-saving effect.
The electric dynamometer is the test core of the whole test bench system. It adopts the variable frequency inverter system as the actuator of the electric dynamometer and adopts Seelong's new generation test and control system as the control core of the test bench system. Seelong software test system is developed based on C# platform and can carry out high dynamic control of the system. Seelong test and control system can automatically complete the relevant setting test cycle and user-defined dynamic test cycle; At the same time, Seelong test and control system can integrate external auxiliary equipment, perform centralized communication and control.
Seelong's test bench system adopts modular design, according to different test requirements and budgets, our professional engineers will customize different dynamometer test bench systems for customers.
Let's become partners, we will provide lifetime free software system upgrade for our dynamometer test bench system (Excluding the development of new applications).
Typical application
1) Research on motor performance test and control
2) Motor efficiency evaluation
3) Feed performance evaluation of motor system
4) Motor durability assessment, etc.
