Technical Characteristics of Our Low-Speed High-Torque Electric Dynamometer:
1. Four-Quadrant Operation: Provides both driving (electric operation) and resistance torque (power generation operation). Remarkable loading performance from zero to rated speed with consistent torque, and constant power above rated speed.
2. Versatile Loading/Driving Modes: Constant torque, constant speed, zero speed, and fixed parameter loading/driving. Dynamic computer-based testing supports various waveform simulations and load spectrum inputs. Capable of simulating real-world conditions like uphill/downhill, start/brake, and acceleration/deceleration.
3. Superior Speed Regulation: Bidirectional, frequency conversion with dynamic response time under 8ms (dependent on test piece inertia).
4. Advanced Torque Control: Utilizes torque vector frequency conversion control with dynamic response under 5ms.
5. Flexible System Operation: Offers manual and automatic program control. Seamlessly switch between multiple control modes without disturbance.
6. Digital Test Bench Operation Modes:
a. Automatic Speed Control
b. Automatic Torque Control
c. Program-Controlled Road Resistance Simulation: Includes road condition, speed, slope, and torque control modes.
d. Speed/Torque Control Switching: Smooth dynamic operation with a switching time less than 1 second.
7. Exceptional Overload Capacity: Handles 150% over-torque for ≥10 minutes, 200% over-torque for ≥1 minute. At zero speed (0Hz), it maintains 200% rated torque without performance degradation.
