Product Details
Dynamometer, as the key equipment of power mechanical performance testing, is widely used in the field of performance testing and research and development of automobiles, engines, motors, wind power generation, ship propulsion systems and various industrial power equipment. It can not only measure the output torque, speed, power and other key parameters, but also simulate the actual working conditions to evaluate the performance, efficiency, durability and emissions of the equipment.
Features: The absorbed mechanical energy is converted into electrical energy through the power electronic converter to feed back to the grid or for other purposes to achieve energy recovery. It has the advantages of high precision, wide speed range and fast dynamic response.
Application: It is widely used in the testing of automobile engines, electric motors, gearboxes, hybrid power systems, etc., as well as the performance evaluation of electric vehicle drive systems.
Each dynamometer has its own unique application scenarios and technical advantages, the choice should be based on the type of object under test, power range, test needs and budget and other factors. The correct choice can not only improve the test efficiency, but also ensure the accuracy and reliability of the test results.
- Dynamometer controller, designed for use with dynamometers, measures parameters such as motor speed, torque, and output power. It can connect to digital power meters to measure motor efficiency and can connect to industrial computers to use human-machine interaction systems for testing motor characteristic curves.
- Advanced hardware design: integrates the advanced and efficient STM32F4 chip, with a working frequency of up to 168MHz, and the floating-point operation DSP instructions greatly enhance computing power; the advanced pulse detection circuit can connect to most torque and speed sensors on the market.
- Strong anti-interference capability: the design prioritizes the electromagnetic compatibility of the controller, modularizing the MCU, and effectively isolating noisy and non-noisy signals; a 4-layer high-density printed circuit board with a complete ground plane division and reasonable layout and wiring greatly reduces external interference.
- Equipped with 2 serial RS232 ports, 1 RS485 bus interface, 1 USB interface, 1 CAN interface, and 1 Ethernet port, it can connect to computers, digital power meters, or other devices with RS485 bus.
- Integrates an advanced intelligent PID control algorithm to automatically control the size of the excitation current, maintaining the stability of torque and speed.
- Integrates an advanced intelligent dynamometer rapid testing algorithm that can quickly and dynamically test the motor's characteristic curves.
- According to the torque range of the dynamometer, the corresponding range can be set to match it.
- The excitation current can be manually adjusted to change the load of the dynamometer, or the load can be automatically adjusted by a computer.
- Easy to use, simple operation, and fast testing speed.
