Le banc d’essai moteur de la société HV Hipot Electric Co., Ltd. permet à de nombreux techniciens du secteur électrique de réaliser divers essais électriques plus facilement.
Rôles et fonctions spécifiques
Les bancs d’essai moteurs modernes (notamment pour les moteurs d’entraînement à énergie nouvelle) remplissent généralement les fonctions spécifiques suivantes :
1.Precise Parameter Measurement:
Electrical Parameters: Voltage, current, power (input/output), efficiency, power factor, harmonics, etc.
Mechanical Parameters: Speed, torque (dynamic and static), power (mechanical output).
Thermal Parameters: Motor winding temperature, housing temperature, coolant inlet/outlet temperature, etc.
Control Parameters: Response to controller (MCU) commands, CAN bus communication messages, etc.
2. Cartographie de la courbe caractéristique :
MAP Chart (Efficiency Map): One of the core outputs of motor testing. It comprehensively displays the efficiency distribution of the motor at different speeds and torques, serving as key evidence for evaluating motor economy (e.g., electric vehicle range).
Torque-Speed Curve (T-N Curve): Displays the motor’s output capability range, including constant torque and constant power zones.
Performance Curves: Such as efficiency curves, power curves, etc.
3. Simulation des conditions de fonctionnement et essais de tenue :
Simulate real loads, such as vehicle operating conditions under different road conditions (e.g., climbing, acceleration, cruising).
Perform predefined endurance cycle tests (e.g., full-load cycles, thermal shock cycles) to accelerate motor aging and evaluate its lifespan and reliability.
4. Essais fonctionnels :
Controller (MCU) Matching Test: Verify the of the motor and controller, including response speed, control accuracy, regenerative braking function, etc.
Fault Diagnosis and Protection Testing: Actively inject faults (e.g., overvoltage, undervoltage, overcurrent, overheating, short circuit, Hall sensor failure) to test whether the motor system’s diagnostic and protection functions are triggered correctly.
5. Essais NVH (bruit, vibrations et dureté) :
Equipped with high-precision sensors to analyze the series resonances of vibration and noise under different operating conditions, providing data for optimizing the motor’s NVH performance.
