One, what is the wattage of the rolling door motor?
1、Electric rolling door
Common electric rolling door motor power ratings typically range from 0.75kW, 0.9kW, 1.2kW, and 1.5kW. Due to its insufficient power, the 0.75kW model is gradually being phased out of the market. The 0.9kW, 1.2kW, and 1.5kW models are the most commonly used. The power of the motor is usually determined by the size of the door. Doors with a width of 2-3 meters are typically best suited for 0.9kW motors, while larger doors require larger motors.
2、Fire-resistant rolling shutter doors
Fireproof rolling shutter doors have different power types depending on the rolling shutter method. For up-and-down rolling shutters, a power of 0.55kW is generally recommended for rolls less than 5 meters, and 0.37kW for rolls less than 3.5 meters. For rolls between 5 and 12 meters, a power of 0.75kW is recommended. For side-rolling shutters, a power of 0.75kW is recommended for rolls within 10 meters, 2.25kW for rolls within 20 meters, and 3kW for rolls within 30 meters.
Alternatively, you can calculate based on the rolling door area. For areas less than 14㎡, a recommended power of 0.4kW is suggested. For areas between 14㎡ and 28㎡, a recommended power of 0.8kW is suggested. For areas between 28㎡ and 45㎡, a recommended power of 1.5kW is suggested.
3、Garage Rolling Door
The typical power for garage roll-up door motors ranges from 0.15 kW, but the actual power varies depending on the type and size of the door.

Two. What are the classifications of garage door motors?
1. According to structure and working principle:It can be categorized into DC motors, induction motors, and synchronous motors.
- DC motors are suitable for roll-up doors with relatively small door sizes and lightweight door panels. The horsepower of DC motors is not a significant factor, and most large door manufacturers do not use this type of motor.
Synchronous motors can be classified into: permanent magnet synchronous motors, reluctance synchronous motors, and hysteresis synchronous motors. The rotor speed of a synchronous motor remains constant at the synchronous speed, regardless of the load size.
Asynchronous motors can be divided into: induction motors and squirrel-cage motors. The rotor speed of an asynchronous motor is always slightly lower than the synchronous speed of the rotating magnetic field.
2、According to operating speed:High-speed motors, low-speed motors, constant-speed motors, and variable-speed motors.
Low-speed motors are further categorized into gear reduction motors, electromagnetic reduction motors, torque motors, and claw-pole synchronous motors, among others.
In addition to the above types, speed-controlled motors can also be classified as:* Step-adjustable constant-speed motors* Infinite-step constant-speed motors* Step-adjustable variable-speed motors* Infinite-step variable-speed motorsThese further include:* Electromagnetic speed control motors* DC speed control motors* PWM (Pulse Width Modulation) variable-frequency speed control motors* Switching magnetic reluctance speed control motors
