Amusement equipment applications


        ACI Inverter is Successfully Applied to the Amusement Equipment.
  An amusement park is a place where children are free to play. The modern playground will usually have a seesaw, carousel, swing, horizontal bar, parallel bars, rings, slides, a toy house, carousel and labyrinth. These recreational facilities can help children develop the ability to cooperate, make the body strong and learn skills, but also provide entertainment and enjoyment. Among them, the merry go round is the children most like to play a kind of recreational facilities, the traditional Trojan to a fixed speed operation, lack of interest and excitement.
    With the development of frequency inverter technology, the Trojan horse can rotate at different speeds, which Not only increases the entertainment, but also saves the electric energy. ACI converter successfully applied to 88 rotating Trojan. The Trojan is the two layer design with 12 meters equipment diameter, 15 meters rails and 14 meters equipment height. The total of equipment weight is 44 tons which 88 people can sit on. The main drive motor is a three-phase 380V/25KW six pole motor.

一.Characteristics of ACI inverter
 1.DSP vector control of special processor for motor
 2.Dynamic performance is stable, fast response, suitable for frequent starting and reversing occasions
 3.Rich terminal functions , meet different needs
 4.Low frequency torque output 150%, speed accuracy 0.5%, low frequency operation characteristic is good
 5. Standard RS485/Modbus communication interface, built-in PID, simple PLC
 6、Adjustable carrier frequency, mute operation
 7.Compact size, easy to install, easy to operate
 8.The whole mount SMT production and conformal coating process
 9.Comprehensive protection function, safe operation
二.ACI inverter for the transformation of the rotating Trojan
1.Transformation requirements
    Trojan horse firstly runs for 30 seconds by 20HZ,then 30 seconds by 30HZ,then 1 minute by 40HZ, at last, runs for 30 seconds by 50HZ.
2.According to the motor model and the field situation, select the 37KW general inverter, the parameters are set as follows;

三.Effect after modification
1.The motor does not need long-term high speed operation, the operating current is greatly reduced, and the power saving effect is remarkable;
2.As the inverter replaces the hydraulic coupling, eliminating the mechanical and hydraulic coupling high fault rate of defects, equipment maintenance costs reduced;
3.Motor running vibration and noise decreased obviously, the bearing temperature also has the very big drop;
4.AC frequency conversion governor, with strong applicability, high reliability, easy operation and other advantages, by the user's welcome.
