The eddy current dynamometer is one of the most advanced loading equipment in China, particularly for the power and micro-power dynamic mechanical loading tests, including both low-speed and high-speed loading tests for various dynamic mechanical systems. Compared to other types of loading equipment, it offers a significant advantage in terms of performance, cost, reliability, and maintenance.
YWZ series electrical eddy current dynamometers are specifically designed for the output characteristics of small and medium-sized internal combustion engines. They feature a simple structure, wide testing area, and excellent repeatability, making them highly suitable for various small and medium-sized internal combustion engines and their components, as well as for power performance testing and load application under different operating conditions.
Key Features:
Simple structure, easy operation and maintenance.
Large braking torque, stable operation.
Low rotational inertia, fast dynamic response, high low-speed torque.
Complements the measurement and control system, enabling automated control.
I. Working and Environmental Conditions for Product Use
Electrodynamic eddy current brakes are equipped with a dedicated matching current stabilizing power supply.
Cooling water is ordinary freshwater; water pressure: 0.02～0.1 Mpa; specific water flow rate is shown in Figure 9.
Ambient Temperature: -10℃ to 40℃
Relative Humidity: 20～90% RH
II. Main Technical Parameters
1. Key performance indicators are listed in Tables 1 and 2.
2. Cooling Water Pressure: 0.02～0.1 Mpa. Adjust the water pressure based on the outlet water temperature; increase the pressure slightly as the outlet water temperature rises to lower it.
Cooling Water Flow: The cooling water volume depends on the temperature difference between the incoming and outgoing water and the size of the absorption power, see Figure 9 for details.
3. Electric eddy current brake outlet water temperature ≤ 55℃
Note: The WZW-P type is a low-speed, high-torque series of eddy current brakes.
