¿Cuál es la diferencia entre el motor de puerta rápida Baojiu A1 y la serie A2?

1. Motor performance
A1 Series:
It adopts ordinary asynchronous motors, which are suitable for scenarios with a daily switching frequency of ≤300 times (such as small warehouses and shops).
El control de aumento de temperatura es general (se permite 70 ° C), y se requiere enfriamiento por intervalos para una operación continua.
A2 series:
Equipped with permanent magnet synchronous motor (some models), the efficiency is increased by 15%, and it supports 24-hour uninterrupted operation.
Built-in temperature sensor, automatic overheating frequency reduction protection.

2. Intelligent control
A1 Series:
Basic functions: infrared collision avoidance, manual emergency stop.
There is no data interface, and it cannot be connected to the intelligent system.
A2 series:
Support PLC programming, can set multiple speeds (such as close deceleration, full speed in the middle).
Optional IoT module (remote monitoring of switch frequency, fault alarm).
3. Environmental adaptability
A1 Series:
Working temperature: -10°C~ 50°C, humidity ≤85%.
No se recomienda para su uso en ambientes polvorientos y corrosivos.
A2 series:
Wide temperature design (-30°C~ 60°C), optional explosion-proof model (Ex dII.CT4).
The bearings are made of stainless steel and are resistant to salt spray corrosion (suitable for coastal areas).

4. Mechanical structure
A1 Series:
Cast iron housing with a large weight (1.5kW approx. 25kg).
Belt drive, the tension needs to be adjusted regularly.
A2 series:
Aluminum alloy housing, lightweight (30% lighter than A1 in the same power).
Optional gearbox direct connection for maintenance-free design

Selection suggestions

Choose A1 series:
✅ Limited budget, small door body (≤4 m)
✅ Low daily use frequency (e.g. supermarket entrance and exit)
✅ There is no need for intelligent management
Choose A2 series:
✅ High frequency (>500 times/day), large load (>5m door)
✅ Data networking or precise positioning is required
✅ Extreme environments (low temperature, high humidity, explosion proof)

Sumario:
A1 is a cost-effective choice for standard working conditions; The A2 is fully upgraded in terms of performance, intelligence and durability, suitable for harsh industrial scenarios.
If budget allows, give preference to the A2 series (lower overall cost for long-term use)
