Product introduction
The Series VS1 Permanent Magnet DC Motor is a high-performance, precision-engineered motor specifically designed for vacuum circuit breaker (VCB) operating mechanisms. Built for reliability and efficiency in medium-voltage (12kV–40.5kV) power distribution systems, this motor ensures fast, stable, and maintenance-free operation in critical switching applications.
Key Features
1. High Torque & Precision Control
-
High torque density (up to 50 N·m) for rapid spring charging
-
Precise positioning (±0.5°) with optional encoder feedback
-
Smooth start-stop with minimized cogging torque (<3% of rated torque)
2. Robust & Reliable Construction
-
IP67-rated sealed housing (dustproof & waterproof)
-
Stainless steel shaft & corrosion-resistant terminals
-
Class F insulation (155°C thermal resistance)
3. Smart & Adaptive Operation
-
Built-in protection (overcurrent, overheating, and stall detection)
-
MODBUS RTU communication for remote monitoring
-
Auto-recovery function after fault conditions
