Features & Functions

1. The dynamometer motor supports both torque control and speed control.

2. The dynamometer motor controller adopts direct torque control (DTC) technology.

3. The dynamometer motor can operate in four quadrants; braking resistors are used under load condition.

4. Power analyzer with motor measurement module is used for steady-state test items; NI acquisition cards with speed-torque sensors are used for transient test items; angle encoders are used for angle-related test items.

Our advantages

1. Accuracy, Speed & Stability
Accuracy: Self-developed power analyzer realizes closed-loop loading control for precise torque loading, synchronously measuring torque
Speed: High-speed acquisition, standard 1ms sampling (customizable to 0.2ms for non-standard needs).

Stability: Extensive background data processing ensures effective values, high consistency and small errors; 

2. Optimization vs. Traditional Dynamometers
We adopt closed-loop loading with precise N·m unit control; traditional dynamometers use open-loop excitation current adjustment, which is imprecise and not in N·m units.

3. Bench Reliability
Most of our test benches feature independently developed hardware and software.

4. Design Flexibility
Mechanical designs (2D, 3D, horizontal, guide-rail) support non-standard customization; multi-bench designs (e.g., one-drive-six) with expansion space reserved; software supports secondary development.

5. High Safety Factor
Equipped with automatic emergency stop and multi-parameter overload protection for effective system safeguarding.

6. Wide Test Coverage
Motor Types: Single/three-phase asynchronous, permanent magnet synchronous, brushless/brushed DC, stepper, linear motors; EV drive, servo, robot, hub, EPS, wiper, pump, fan motors, etc.
 Power Range: 40W - 1000kW
Torque Range: 10mN·m - 50kN·m
 Speed Range: 1rpm - 40000rpm

7. Technical & Research Support
45 R&D staff (4 senior engineers); university-enterprise cooperation with Zhejiang University, China Jiliang University and China University of Mining and Technology (theory from universities, practice from us).

8. Delivery & Pre-Testing Advantages
Alternative solutions for urgent orders; preliminary data available in advance via partnerships with testing institutions (Fangyuan, CEPREI, CVC WeiKai).

9. Standard & Quality Control Systems
Compliant with ISO 9001/14000; proprietary quality control system with MES for real-time process monitoring.

10. Appearance
Refined and elegant, suitable for laboratories/equipment rooms; conveys reliability to visiting customers.

11. Precision
Control precision (within ±1rpm) is better than measurement precision.

12. Company Profile
Founded in 2009; 10,000 square meter facility; ~100 staff (45 R&D, 4 senior engineers); annual output value ~80 million RMB.
