What kind of motors are generally used for rolling shutter doors?

The following types of motors are commonly used for rolling shutter doors, which are selected according to different drive modes, power and application scenarios:

1. Tubular motor (tubular motor)

Features:

The motor is cylindrical and directly installed in the roller of the rolling door. It has a compact structure, saves space, and runs quietly.

Applicable scenarios:

Household rolling doors, light rolling doors for shops, garage doors, etc.

Subdivision types:

AC tubular motor: low cost, simple maintenance, suitable for frequent start and stop.

DC tubular motor: with battery backup power supply, can be manually operated during power outage, and is safer.

2. External motor (worm gear motor)

Features:

Driven by worm gear reduction mechanism, with high torque and low noise, usually installed on the side or top of the door body.

Applicable scenarios:

Medium and large commercial rolling doors, industrial doors (such as warehouses and factories).

Advantages:

Supports high load (up to 1000kg or more), long life, suitable for frequent use.

3. Track motor (linear motor)

Features:

The motor moves linearly along the track and directly pulls the door body without the need for a traditional roller.

Applicable scenarios:

Heavy industrial doors, fireproof rolling shutter doors, and installation environments with limited space.

4. Fireproof roller shutter motor

Features:

Must comply with fire protection standards, usually linked to the control system, and have the function of automatic lowering when power is off.

Drive type:

May use external motor or tubular motor, but must pass fire protection certification.

5. Remote control/smart motor

Features:

Integrated wireless remote control, mobile phone APP control or smart home linkage (such as access to WiFi, Zigbee).

Applicable scenarios:

Modern families, smart shops, improve convenience.

Selection considerations

Door weight: For light doors (such as home use), choose tubular motors; for heavy doors, choose external turbine motors.

Frequency of use: For high-frequency commercial/industrial scenarios, choose durable motors (such as external motors).

Safety requirements: Fire doors require special motors; garage doors can choose DC motors with resistance and rebound.

Power outage emergency: DC motors or models with backup power are more reliable.
