AC Electric Tourist Cars Overview
The difference between the AC variable frequency motor and the ordinary DC motor is similar to that of the ordinary DC electric sightseeing car. The motor is designed based on the frequency of the electricity and the corresponding power. The stable operation can only be performed under the rated conditions. The AC variable-frequency electric sightseeing car AC frequency conversion motor does not exist these conditions, at low frequencies also operate as usual, in the process of driving completely to bring visitors a relaxed, comfortable and smooth pleasure. AC frequency conversion electric sightseeing car is very outstanding in environmental protection and energy conservation. It is far superior to DC electric sightseeing car. Take a motor with a power of 55KW as an example: When the speed is reduced to 4/5 of the original speed, its power consumption It is 28.16KW, saving 48.8%. When the speed drops to 1/2 of the original speed, the power consumption is 6.875KW, which can save 87.5%. At the same time, its characteristics of stable performance, high efficiency, energy saving, strong bearing capacity, high safety, strong braking, no-burning motor, strong climbing power, smooth starting when driving, high speed, low noise, wide vision, etc. Tourism and tourism needs. The maximum speed of the DC battery electric sightseeing car is 40 km/h, and the maximum driving distance for a single charge is about 80 km. The maximum speed of the AC variable-frequency electric sightseeing bus can reach 60 km/h and the maximum driving range is 100 to 140 km. At present, only a company in Shenzhen Luzhou Local Boat Electric Vehicle Co., Ltd. has fully owned the research and development and production technology of AC variable-frequency electric sightseeing vehicles, and its performance and core technologies are in a global leading position. Main land: 1. Golf course; 2. Park area; 3. Amusement park; 4. Real estate; 5. Resort; 6. Airport; 7. Campus; 8. Comprehensive community patrol; 9. Factory area; AC frequency conversion electric sightseeing car system principle comparison: The principle comparison of the driving system of AC frequency conversion electric sightseeing car and ordinary DC electric sightseeing car: (1) Principle of ordinary DC sightseeing vehicle drive system:

AC frequency conversion electric sightseeing car refers to the car power supply as the driving force, using AC frequency conversion motor drive wheels, specifically for the tourist attractions, parks, large amusement parks, closed communities, campus, garden hotels, resorts, villas, urban pedestrian street, Self-driving tour developed in areas such as harbors, regional patrols, and environmentally-friendly electric passenger vehicles dedicated to transportation.
(2) Principles of AC Frequency Conversion Electric Sightseeing Vehicle Driving System (taking the example of AC frequency conversion electric sightseeing car of Shenzhen Luzhou Zhouzhou Electric Vehicle Co., Ltd.):
1. The Land Cruiser AC Electric Sightseeing Vehicle adopts a large-capacity lead-acid sealed battery as an energy storage device. Its storage and power supply performance is good, its energy utilization rate is as high as 92%, its power supply is stable, and its charging time is short. This makes the vehicle continue to operate for a long period of time. No maintenance, no need to add acid, water, battery life is long, generally can be used for three years. 2. The frequency conversion controller adopts the DSP control chip imported from the United States, which is equivalent to microcomputer control, stable performance, and electric energy controlled by frequency. It is currently the leading technology in China. The controller is independently developed by the company, and the quality and maintenance are guaranteed. Low maintenance costs. 3, the use of AC variable frequency motor as a driver, stable performance, anti-overload capability, no burning motor, climbing power is strong. Smooth starting, speeding up, long distance, low noise and strong carrying capacity when driving make passengers feel more comfortable.
The frequency conversion electric sightseeing car AC frequency conversion motor adopts special electromagnetic structure optimization design that is different from the ordinary DC motor, so that the motor torque, power, and efficiency can reach the optimum within a wide range of speed. This series of motors have the characteristics of high efficiency, high peak power, high overload capacity, stable and reliable performance, compact structure, small size, light weight, and maintenance-free driving motor for electric vehicles, which are not available in other similar motors. Frequency conversion motor base speed following constant torque operation to meet the requirements of fast start, acceleration, climbing and frequent starting of electric vehicles, constant speed above base speed operation, high torque when the motor runs at high speed, so that the electric vehicle can get good high speed performance. It can meet the requirements of various operating conditions for electric vehicles. At the same time, as a generator to provide energy feedback during downhill, high-speed taxiing and braking, the battery is recharged to increase the mileage of the vehicle.
