Among all the amusement park rides, the carousel is undoubtedly one of the most popular attractions, especially among children. However, traditional carousels operate at a fixed speed, lacking excitement and thrill. With the development of frequency conversion technology, carousels, equipped with frequency converters, can rotate at different speeds according to demand, improving both entertainment value and energy efficiency.
Safety requirements for carousels are very high. To ensure children's safety and riding comfort, the main rotating motor of the equipment not only needs smooth acceleration and deceleration and stable operating speed, but also requires balanced motor output torque. ENA100 frequency converters have been successfully applied in various amusement equipment, operating stably and reliably, and bringing significant economic benefits to amusement facility manufacturers and retailers. Below, we will introduce the application of the ENA100 frequency converter on a carousel in an amusement park in Guangdong.
Equipment Introduction
Structural composition: The carousel equipment is divided into a top, middle and bottom section, with a central column running through the top, middle and bottom of the entire equipment.
The top of the equipment consists of an umbrella frame, an outer edge of the umbrella frame, connecting rods for the umbrella frame, umbrella fabric, and umbrella fabric ropes. Combined with the surrounding fiberglass decorations, a crown ball, polycarbonate panels, and light troughs, it forms a beautiful roof. The middle section of the equipment is mainly connected by a central fiberglass waist, outer support rods, and a central horse pole. The horse pole runs through the horse's body, stirrups, and the lower horse cover.
The bottom of the equipment consists of a motor, a large disc, rails, rail connecting rods, wheels, and external decorations. It rotates by being driven by the motor.
System Configuration
The on-site carousel transmission system uses the ENA100 series vector frequency converter to drive a three-phase asynchronous motor to rotate the large disc. The speed can be adjusted in real time according to the operating requirements to control the carousel to start and stop smoothly.

Application advantages
01. The ENA100 frequency converter is compact and saves installation space; it is quick and easy to operate, and the rotation speed can be freely adjusted according to the carousel's operating requirements. This reduces system design and maintenance costs while making the equipment more energy-efficient.
02. The ENA100 features an advanced control algorithm, with 150% rated torque output at 0.25Hz and speed control accuracy up to ±0.5%, ensuring that the carousel can start with low frequency and high torque when fully occupied, with balanced motor torque output and smooth acceleration and deceleration.
03. It has an overload capacity of 150% of the rated current for 1 minute and is equipped with comprehensive overcurrent, overvoltage, undervoltage, and overload protection functions, making the carousel safe and reliable to operate and earning the trust of users.
