Quelle est la différence entre le moteur à porte rapide de Baojiu série A1 et 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).
The temperature rise control is general (70°C allowed), and interval cooling is required for continuous operation.
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%.
Not recommended for use in dusty and corrosive environments.
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)

Summary :
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)
