Eton Equipment Engineering Ltd provides the following electric motors to the end users: 1. Mine electric wheel dump truck motor （1）source of technology Introduced, digested and absorbed advanced and mature foreign design and manufacturing technologies. （2）Technical characteristics The electric drive is driven by a diesel engine to drive a synchronous traction generator that produces alternating current. The AC power is driven through the control cabinet to drive the traction motors mounted on the left and right sides of the rear axle. The motor outputs mechanical torque, which is transmitted to the hub through the wheel reducer to drive the vehicle. （1）Traction generator The technical scheme of AC synchronous brushless excitation can greatly extend the maintenance cycle of the motor and realize the high altitude operation reliability of the unit. （2）motor Adopting AC variable frequency speed control asynchronous motor scheme Features are as follows: 1. Realize stepless speed regulation; 2. The starting current is small, reducing the capacity of the power supply equipment; 3. Start smoothing, can eliminate the impact of the machine; 4. The power saving effect is remarkable; 2. Motor and electric control equipment for mine excavators First, the motor for excavators 1. Technology source The introduction of advanced technology, re-digestion, absorption, and localization and transformation, quickly improve the company's design and development capabilities. 2. technical characteristics Mining excavators are indispensable mining equipment for large open pit mining. The shovel has both DC drive and AC drive. The DC drive system has a simple control principle and good operating characteristics.The energy-saving and maintenance-free features of the AC drive control system make its overall performance superior to that of the DC electric shovel. The drive motor of the AC shovel uses a three-phase AC variable frequency motor to drive the four mechanisms of lifting, pushing, walking and turning. Has the following characteristics: (1) The external characteristic curves of the four motors are different, and the selection of constant torque point, constant power point and heat load is particularly important. (2) There must be sufficient margin for structural design and performance design. Second, electric excavator electronic control equipment 1. Source of technology The daily electric shovel electric control includes DC unit complete set of electronic control and frequency conversion complete set of electronic control, mainly for the assembly and production of electrical cabinets, the development of electronic controllers and the application of frequency conversion technology. Among them, the core part of the DC unit product is developed by itself. Currently, only Dalian Daily has owned this product and applied for a patent. 2. technical characteristics The daily electric shovel electric control is based on the theme of the electric control cabinet, and the DC generator digital regulator is independently developed. 3. Mine hybrid heavy truck drive motor group source of technology Based on a large number of development experience of new energy vehicle drive motors and mining wheel motors. Technical characteristics According to the motor output characteristic curve, supply voltage, maximum current and other parameters, repeated analysis and optimization to determine the electromagnetic design parameters. The motor base is cooled by a water jacket. The stator winding of the motor is covered with DuPont insulating enamel. The rotor magnetic steel groove type adopts a "V" type groove structure. The hybrid mine truck has a power recovery rate of up to 70% under cyclic conditions of no-load uphill and full load downhill. Statistics after loading operations show that fuel consumption is reduced by nearly 50% compared to fuel vehicles. 4. Motor for track tractor source of technology Relying on its own technological advantages and research and development capabilities, firmly occupy the market in this field Technical characteristics The track traction series motor can be said to be the ace product of our company. Our track traction motor is complete in range, the power level is from 3.5KW to 520KW.. It can support tractors of various tonnages. The products not only meet the needs of the domestic market, but we can also design and manufacture products that meet the requirements of users according to the needs of foreign users. For example, our company is a 520KW pulse-flow traction motor for a large-tonnage traction locomotive of a mining company in Russia. It has been running in foreign mines for many years, and its operational performance indicators have reached user requirements. Through the return visit survey of the user, the user feedback rate of the motor is reduced by 10% compared with the original Ukrainian motor, and the maintenance cost of the motor is reduced by 15%. The heat generation and temperature rise of the motor are greatly improved compared with the original motor. 5. Large shaft lifting series motor source of technology The company has organized technical personnel and senior leaders to learn and discuss advanced technologies at home and abroad through technology introduction, and at the same time evaluate and upgrade the company's existing products. Technical characteristics In 2010, our company successfully built the new main shaft lifting motor for the Kailuan Mining Bureau for the first time, which indicated that the company has the manufacturing capacity of large shaft hoist in the mine field, and once again the main shaft hoist of Kailuan Coal Mine. The motor of KP-6500 is the largest shaft lifting motor at home and abroad. The armature diameter of the motor is 4.1 meters and the total weight of the motor is 110 tons. The manufacturing of the hoist enhances the technical strength and manufacturing capability of our company. 6. Direct drive permanent magnet synchronous belt conveyor motor source of technology After making sufficient market research, the company is ready to enter the field. For this reason,the company will vigorously introduce relevant talents to carry out research and development and prototype production of the product. Technical characteristics The frequency conversion permanent magnet direct drive motor for belt conveyor is divided into external variable frequency permanent magnet direct drive motor and outer rotor variable frequency permanent magnet direct drive motor. Mainly used to drive belt conveyors. Variable Frequency Permanent Magnet Direct Drive Motor for Belt Conveyor Features: Energy efficient Safe and reliable Maintenance free Intelligent control Technical guarantee The company has worked closely with Prof. Zhang Bingyi from the Institute of Electrical and Control Technology of Shenyang University of Technology to develop a permanent magnet direct drive motor using low-speed high-torque gearless transmission system and technology. In-depth study of the same industry manufacturers products, and visit customers to understand the needs of users, the introduction of the industry-renowned manufacturers Shanghai Jingji direct drive motor technology. And optimize and improve on the basis of it. Using industry-leading design software to continuously optimize design products to ensure product quality while reducing production costs and improving product market competitiveness. 7. New energy vehicle motor Logistics, passenger car motor source of technology Under the strong promotion and support of the country, China's new energy automobile industry has mushroomed like a mushroom, as an old-fashioned traction motor R&D and manufacturing enterprise. The day traction motor cooperated with many home appliance control manufacturers earlier to develop a system solution with optimal price ratio. Technical characteristics Compared with the drive motor, the drive motor for new energy vehicles has the following characteristics: The stator core is laminated by a high magnetic permeability low loss punch to improve the efficiency of the motor. The stator punch is molded by a high-precision punch to ensure the manufacturing precision. The rotor magnetic steel trough type adopts a "V" type trough structure, and the magnetic steel is embedded in the trough and then solidified by the potting and solidification of the rotor core.
