Operating Mechanism


Precision Operating Mechanism Manufacturer for Motor Protection Systems


As China's leading operating mechanism manufacturer, HAIPART designs and produces precision mechanisms that serve as the critical "safety guardians" for industrial motor systems. Our mechanisms ensure reliable protection that directly determines equipment lifespan and production safety in modern manufacturing environments.


Why Choose HAIPART Operating Mechanisms?


✅ Advanced Electrical Protection

Precision Current Sensing

±0.5% accuracy Hall effect sensors with 10kHz sampling frequency capture millisecond-level current abnormalities.

Multi-Protection Algorithms

Simultaneous detection of overload, lock-rotor, phase loss, and imbalance conditions with <100ms response time (IEC 60947-4-1).

Thermal Modeling

I²t thermal memory curves dynamically adjust protection thresholds based on motor thermal characteristics.

✅ Robust Mechanical Design

Bistable Trip Mechanism

Dual-spring mechanism ensures single-operation switching with 100,000 mechanical cycles lifespan (GB 14048.4).

Forced Locking System

Maintains contact separation after protection events, requiring manual reset to restore power.

Visual Status Indicators

Tri-color LED diagnostics:                            Red - Short circuit                            Yellow - Overload                            Green - Normal.

✅ Intelligent Control Systems

Industrial Communication

Modbus RTU/Profibus DP protocols for seamless DCS integration and remote monitoring.

Fault Diagnostics

Stores last 10 protection events with timestamps and error codes for failure analysis.

Adaptive Protection

Self-learning algorithms establish motor baselines to detect abnormal vibration (FFT analysis) and insulation degradation.

✅ Space-Optimized Packaging

Compact 12mm-50mm diameter series enables direct PCB mounting, reducing required circuit breaker space by 35% compared to traditional shielded solutions.
