FAQs
1. What are the key differences between a Jackshaft motor and a standard trolley motor for industrial doors?
Industrial sectional doors typically use Jackshaft motors (side-mounted). These drive the torsion bar directly, saving overhead space and allowing for high-lift or vertical-lift tracks. Trolley motors are usually reserved for standard-lift residential or light commercial doors where ceiling space is not an issue.
2.How do I choose the correct motor torque (Nm) for a heavy industrial sectional door?
The torque requirement depends on the door's weight and the drum diameter. For most Chinese industrial motors, a 50Nm to 70Nm motor is suitable for doors up to 400kg, while 100Nm to 150Nm motors are used for extra-large or "oversized" sectional doors. Always ensure the motor's lifting capacity exceeds the door weight by at least 20% for safety and longevity.
3.Do Chinese industrial door motors support 3-phase (380V) or single-phase (220V) power?
Most manufacturers offer both. 3-phase (380V) is preferred for high-frequency industrial use as it runs cooler and is more durable. Single-phase (220V) is available for facilities without industrial power, often utilizing frequency inverter technology to provide soft-start and soft-stop functions.
4. What safety features are standard with these industrial operators?
Quality Chinese industrial motors comply with international safety standards. Essential features include an emergency manual chain (for power outages), anti-fall safety brakes, and ports for safety photocells or sensing edges that stop the door if an obstruction is detected.
5. Are the control boards compatible with international remote frequencies and smart systems?
Yes. Most exporters provide 433.92MHz rolling code receivers, which is the global standard. Additionally, many modern Chinese controllers now include dry contact ports, allowing easy integration with PLC systems, WiFi smart hubs, or warehouse management software.
