Electric Power Dynamometer Motor Factory Dynamometer Test Bench

Product Description

Product Description

I. Test Items: Based on customer testing requirements, this system can perform the following tests on motors:
1) No-load test
2) Locked-rotor test
3) Load test
4) Temperature rise test
5) M-S curve

II. System Functions
1. The system displays real-time motor data including three-phase voltage, three-phase current, input power, frequency, power factor, torque, speed, output power, and efficiency.
2. The system analyzes load test results to determine full-load current, full-load power, full-load efficiency, full-load slip rate, and full-load power factor, generating corresponding curves.

III. Technical Specifications
1) Voltage measurement range: AC 0–500V
2) Current measurement range: Depends on current transformer
3) Measurement accuracy for voltage, current, power, and other electrical quantities: ±0.5%
4) Torque measurement range: Depends on torque sensor
5) Torque measurement accuracy: ±0.5%
6) Speed measurement range: Depends on speed sensor
7) Speed measurement accuracy: ±1 rpm
8) Resistance measurement range: 0–20 kΩ
9) Resistance measurement accuracy: ±0.2%
10) Temperature measurement range: 0–100°C
11) Temperature measurement accuracy: ±0.1°C
12) Torque control accuracy: ±2%

IV. Equipment Configuration and Technical Parameters
1. Test Power Supply
1) Test power supplies are configured with different types and sizes based on customer requirements.
Variable frequency power supplies are recommended, as they can automatically set output voltages via computer, compensate for voltage drops at the motor terminals, or be equipped with high-power voltage regulators.
2) Sufficient power capacity is required: Locked-rotor tests and MS curve tests demand 4–7 times the motor's rated current. Therefore, test power supply selection: 3KVA; maximum current capacity: 3KVA/660V = 4.5A. If the motor's starting current exceeds this value, reduced-voltage starting is required.
2. High-Voltage Components
1) High-voltage cabinet: Range conversion system comprising PLC, current transformers, and contactors
2) The laboratory site must install reliable grounding and a five-wire power supply system on-site according to electrical standards. All electrical equipment, instruments, computers, and sensors must be reliably grounded.
3) Power cables and motor cables shall be provided by the user based on site requirements or supplied by our company.
3. Load System
Utilizes an AC dynamometer to perform loading tasks within 200–1000W and 0–3000rpm.
4. Measurement of Torque, Speed, and Output Power
5. Electrical Quantity Measurement
6. Armature Resistance Measurement
7. Temperature Measurement
8. Computer, Software System, and Control Cabinet

After Sales Service
