Aplicación y selección de motor especial de puerta de obturación rápida de PVC

1. The core advantages of fast gate motors
Strong adaptability
Specially designed for PVC fast doors, it supports door body width of 2~6 meters (power coverage 0.75~2.2kW), standard frequency conversion control, and adjustable start and stop speed (0.8~1.5m/s).
Compatible with 24V/220V/380V voltages, suitable for most industrial power scenarios in China.
Outstanding durability
It adopts all-copper wire winding, insulation level F (temperature resistance 155°C), protection level IP55 (dustproof and waterproof), and bearing life > 100,000 times.
The temperature rise of the motor is ≤ 80K (national standard GB/T 755-2008), and continuous operation does not reduce the frequency.
Intelligent control
Built-in PLC logic, supports infrared fire collision avoidance, radar induction start and stop, and adjustable resistance rebound sensitivity (20~100N).
RS485 communication is optional, docking with the MES system in the factory.

2. Key steps in selection
Calculate load requirements
Door weight (kg)× Lifting speed (m/s)÷ Transmission efficiency (0.9)≤ Rated torque of the motor. Example: 4m wide door (about 80kg), speed 1.2m/s → Torque required ≥80×1.2/0.9≈107N·m, choose BJ-2200P.
Adaptation to the environment
Low temperature environment (below -20°C): optional heating belt and low temperature grease.
High-frequency use (>500 times/day): Upgrade to BJ-2200P forced air cooling kit.
Safety certification
It needs to pass CE and ISO9001 certification, and food factories give priority to FDA-compliant models

3. Installation and maintenance points
Mechanical installation
The deviation between the motor shaft and the drum center <0.1mm, and the belt tensioning force is calibrated with a tension meter (recommended value: 15~20N/mm²).
Electrical wiring
When the phase of the three-phase motor is wrong, it can be quickly identified by the LED alarm light on the control board (red light flashes twice).
Troubleshooting
E01 Code: Overcurrent Protection → Check rail resistance or voltage stability.
E05 Code: Encoder Abnormality → Clean the photosensor or replace the shield wire.
