★Unique design reduces the failure rate of the limit control system;
★Excellent self-locking performance (braking distance less than 10mm), solves the problem that the ventilation system is not tightly closed;
★Overload protection, phase loss protection function, reduce the burning rate of the motors;
★Add the manual open and close device:
1. Limit switch can be adjusted by one peison, saving half of the working hour;
2. Eliminate the concern that the system still needs open and close when power is off.
1. Product Advantage
(1) Unique design reduces the failure rate of the limit control system
(a) On the market, most of the gear motor has the same fatal weakness, bad self-locking performance; braking distance is too long, generally between 50mm-100mm. Then breaking the window system, open and close is not tight. This is caused by its Transmission system, cannot be improved;
(b) Generally, the braking distance should be less than 10 mm, then, it can meet the high requirement for the Venting system. Since 3GG® Gear Motor adopts special transmission system, self-locking performance is highly improved. The braking distance is less than 5 mm under 5.2rpm which can fully meet the high requirement of the Venting system, extend its service life.
(2) Excellent self-locking performance (braking distance less than 10mm), solves the problem that the ventilation system is not tightly closed
(a) At present, the most common quality problem of the Gear Motor is the damage to the limit switch control system. The main reason is that the self-locking performance of the gear motor fails to be qualified and the braking distance is too long. (5.2rpm, braking distance 50-100mm), the failure rate is higher to 5%. When the braking distance is less than 20mm, the failure rate will be greatly reduced;
(b) The 3GG® Gear Motor is less than 5 mm (5.2 rpm) and the failure rate is reduced to 0.5% from 1%.
(3) Overload protection，phase loss protection function, reduce the burning rate of the motors
3GG® Gear Motor adds overload protection and power phase loss protection functions to the limit switch control system. When the load exceeds 1.5 times than the rated load or when the three-phase power supply becomes two-phase, it automatically stops working. After troubleshooting, the motor runs again.
(4) Add the manual open and close device, eliminate the concern that the system still needs open and close when power is off
If there is a power failure, we can use the wrench for manual operation to open or close the window. This prevents the indoor plants or animal in danger situation when the temperature is too high. For manual operation, it will only need manual rolling 360 circles, open the window within 15 minutes. This can meet the customer’s requirement. Now, among all the gear motor on the market at home and abroad, only 3GG® Gear Motors can achieve the manual opening and closing when the power is suddenly off.
