Gaxiao High Volume Low Speed Industrial Fans Infinitely Variable Speed
Posted by gaxiao on June 16th, 2019
There are two kinds of control systems for industrial domestic and abroad fans ,one is 3-5 gear speed, the other is infinitely speed regulation. Gaxiao high volume low speed industrial fans, #hvls fan #high volume low speed fan #industrial ceiling fan #ceiling industrial fan, equipped with Schneider three gear switch and infinitely variable speed knob，allow customers to achieve convenient from zero to the maximum speed of any regulation.
The infinitely transmission function of the motor can be divided into mechanical transmission and electric transmission ,according to the different transmission modes of the motor. High volume low speed industrial fans, as high-power equipment, are basically driven by more advanced electric power.
Power transmission is basically divided into three categories:
- One is the electromagnetic sliding type, which is installed in the asynchronous motor of an electromagnetic slip clutch, by changing it’s excitation current to speed, which belongs to a relatively backward way of speed regulation.It features simple structure, low cost, easy operation and maintenance; sliding maximum, low efficiency, severe heat, not suitable for long-term load operation, so it is generally only used for small power transmission.
- The second type is dc motor type, by changing the flux or changing the armature voltage to achieve speed regulation.Its characteristic is the speed regulation scope is big, the accuracy is also high, but the equipment is complex, the cost is high, the maintenance is difficult, is generally used in the middle power scope (dozens to several hundred kilowatts), has been gradually replaced by the ac motor type.
- The third type is ac motor type, through pole change, voltage regulation and frequency conversion for speed.The most practical application is frequency control, that is, using a converter to obtain a variable amplitude power supply, and then drive the motor speed.It is characterized by good speed regulation performance, wide range, high efficiency, can be automatically controlled, small size, suitable for a wide range of power: mechanical characteristics in the deceleration section for constant torque, low speed and low efficiency and operation is not smooth, high price, maintenance needs professional personnel.

After years of improvement,Gaxiao has changed from the traditional gear type speed adjustment to the infinitely speed adjustment, which enables customers to adjust the speed according to the situation of the site, avoiding the disadvantages of the traditional gear or high or low.
