Product Description

 
Our state-of-the-art low-speed and high-torque electric dynamometer is a pinnacle of modern dynamic simulation technology, designed for power loading and reverse dragging. Leveraging the advanced speed and torque control technology of four-quadrant AC asynchronous motors, this versatile equipment is a vital asset in both vehicle and component test benches. It boasts superior loading capabilities, seamlessly handling low-speed high-torque as well as high-speed high-power test pieces. This ensures comprehensive performance and durability testing across diverse speed and power ranges.

Remarkable Features of Low-Speed High-Torque Electric Dynamometer:
Capable of both driving and reversing in constant speed mode, the electric dynamometer offers unparalleled flexibility.
It also provides reliable dynamometer loading in constant torque mode, ensuring consistent performance.
During dynamometer loading, the emitted energy can be efficiently fed back to the grid or dissipated via a chopper brake resistor, enhancing energy efficiency.
Our low-speed, high-torque electric dynamometers eliminate the need for a cooling water system, simplifying operation and maintenance.

Technical Specifications of Low-Speed High-Torque Electric Dynamometer:
1. Four-Quadrant Operation: This system can provide driving torque (electric operation) as well as resistance torque (power generation operation). It maintains constant torque from zero to rated speed and ensures constant power above rated speed, offering exceptional loading performance.
2. Versatile Loading/Driving Modes: The system supports constant torque, constant speed, zero speed, and fixed parameter loading/driving. It can also be computer-controlled, simulating various conditions such as uphill, downhill, start, brake, acceleration, and deceleration. Its ability to input load spectra for dynamic testing is unparalleled.
3. Speed Regulation: The system features bidirectional, frequency conversion speed regulation with a dynamic response time of less than 8ms, depending on the test piece's inertia.
4. Torque Control: Utilizing torque vector frequency conversion control, it achieves a dynamic response time of under 5ms.
5. Operation Modes: The system supports both manual and automatic program control, allowing seamless switching between various control modes without disturbance.
6. Digital Test Bench Operation Modes:
a. Automatic Speed Control
b. Automatic Torque Control
c. Program-Controlled Road Resistance Simulation: This includes simulating road conditions, speed control, slope control, and torque control.
d. Dynamic Switching: The test device can switch smoothly between speed and torque control modes during dynamic operation, with a switching time of less than 1 second.
7. Overload Capacity: The system can handle 150% over-torque for up to 10 minutes and 200% over-torque for up to 1 minute. At zero speed (0Hz), it can reach 200% of the rated torque, and the speed can reduce to zero without torque attenuation.
