1、 Analysis of the entire series of core products, precise adaptation to diverse scenarios
The product system of Ningbo Naiweide Electric covers four core requirements: power starting, power supply, vibration operation, and traction lifting. Each category has been professionally designed for specific application scenarios, balancing performance and practicality.
（1） Starter series: the "power engine" that starts equipment
As the starting core of internal combustion equipment, the starter motor undertakes the key task of converting electrical energy into mechanical energy to drive the engine operation. Ningbo Naiweide has created three major sub series of starter motors for excavators, forklifts, and trucks based on the differences in working conditions of different vehicle models.
The excavator starter focuses on the harsh working conditions of construction machinery and is designed with 24V voltage, with a power coverage of 3-10kW. It is compatible with mainstream excavator models such as Sany SY215C/SY365H and Caterpillar 320D/336D. The core components are series excited motors and high-strength one-way clutches, which can resist vibration and dust invasion in mines and construction sites. Forklift starters consider both flexibility and energy efficiency, with two voltage options of 12V and 24V and a power range of 1.5-3kW. They are compatible with internal combustion forklifts such as the H2000 series and Hangcha A series, and have built-in external meshing or planetary gear reduction mechanisms, resulting in low starting noise and low energy consumption. The truck starter is designed according to the vehicle type classification, with a power of 1-3kW for light truck models and 6-10kW for heavy truck models. It is suitable for mainstream trucks such as Jiefang J6L/J7 and Dongfeng Tianlong KL. The support of planetary gear reducer makes its starting torque stronger, meeting the high reliability requirements of long-distance transportation.
（2） Generator Series: The 'Stable Heart' for Whole Vehicle Power Supply
The generator is the core of the equipment's power supply, which is driven by a belt during engine operation to charge the battery and ensure the normal operation of the entire vehicle's electrical equipment. Ningbo Naiweide's generator series achieves full scene coverage for excavators, forklifts, and trucks, with a unified voltage of 12V/24V to meet different equipment requirements.
The generator power suitable for excavators is 2-4 kW, with a built-in regulator and a belt pulley pitch diameter between 100mm and 120mm, which can stably adapt to the power supply needs of excavators from brands such as Sany and Caterpillar; The forklift specific generator has a power of 0.8-2kW and is equipped with multi wedge pulleys, perfectly matching the low load power supply scenarios of storage and logistics equipment such as Heli and Hangcha; The truck generator has been reinforced with durability design, with a power of 3-5 kW and an output current of 100-200A, which can meet the needs of multiple electrical equipment such as headlights and air conditioning for light and heavy trucks such as Jiefang and Foton to operate simultaneously.
（3） Vibration Motor: Efficient Assistance for Material Operations
The vibration motor generates periodic excitation force through adjustable eccentric blocks at both ends, and is widely used in operations such as material screening, feeding, and compaction. Ningbo Naiweide's vibration motor is based on three-phase asynchronous motors, with a protection level of up to IP54/IP55, suitable for the strict requirements of different working conditions.
On the vibrating screen in the mining sand and gravel field, the model with an excitation force of 10-50kN and a power of 1.5-7.5kW can efficiently complete material classification; The vibration feeder of the factory production line is equipped with a horizontal vibration motor with an excitation force of 5-20kN and a power of 0.55-2.2kW to ensure uniform material transportation; The concrete vibration table in construction uses a vertical vibration motor with an excitation force of 20-40kN, and the impact resistant design ensures that the concrete is compacted and formed.
（4） Winch motor: the "strong responsibility" for traction and lifting
The winch motor is designed specifically for traction and lifting operations, using a DC motor combined with a planetary gear reducer to output low-speed high torque to drive the drum to run. The voltage of this series of products is mainly 12V/24V, with a power of 3-7.5kW and a protection level of up to IP67, suitable for traction needs in multiple fields.
The high-power winch motor on the engineering rescue vehicle, with a configuration of 24V voltage and 5-7.5kW power, can achieve a rated pulling force of 5-10 tons, assisting in equipment rescue under complex working conditions; The off-road vehicle is equipped with a 3-5 kW winch motor, which allows for the selection of 12V/24V voltage. The rated pulling force of 3-6 tons is sufficient to cope with field self rescue; For ship mooring scenarios, the company has also launched a corrosion-resistant shell winch motor with a power of 4-6kW and a rated tension of 6-8 tons, suitable for daily operations of small ships and fishing boats.
2、 Scientific selection guide, adapted to the needs of different industries
The operating conditions of equipment in different industries vary significantly, and the performance requirements for motors are also different. Ningbo Naiweide Motor has developed targeted selection priority recommendations based on the characteristics of its three core application areas: engineering construction, warehousing and logistics, and freight transportation, to help users accurately match products.
（1） Engineering construction industry: weather resistance and durability as the core
Engineering construction scenarios often face harsh environments such as high temperatures, dust, and strong vibrations, and motor selection should prioritize ensuring stability and impact resistance. Firstly, attention should be paid to the protection level. The starter and generator should reach IP54 or above, and the vibration motor should be ≥ IP55; Secondly, power redundancy should be reserved and selected at 1.2 times the rated power of the engine to avoid overload damage; At the same time, it is necessary to strengthen the structural strength, and priority should be given to choosing starter motors with thickened flanges and vibration motors with reinforced bases to extend their service life.
（2） Storage and logistics industry: high efficiency and energy conservation are key factors
The frequency of use of warehousing and logistics equipment is high, and the working environment is relatively clean. The core of selection is to improve efficiency and reduce energy consumption. Prioritize selecting energy-saving forklift starters and generators with an efficiency of ≥ 85% to reduce long-term operating costs; Pay attention to noise control, select products with deceleration mechanism and noise ≤ 75dB, and improve the storage operation environment; At the same time, pay attention to installation flexibility, prioritize the selection of universal interface products, and adapt to the replacement needs of forklifts of different tonnages.
（3） Freight transportation industry: reliability and easy maintenance as the focus
Freight vehicles often run long distances and are difficult to maintain, so the selection of motors should balance durability and convenience. Prioritize the use of truck starters equipped with wear-resistant electric brushes and generators with long-lasting bearings to enhance product lifespan; Accurately match motor power according to truck displacement to avoid excessive or insufficient power; Choose products with modular design to facilitate component disassembly and replacement, reducing losses caused by failures during transportation.
In addition, when selecting, three general points should be noted: strictly match the voltage system, prioritize 24V for construction machinery and heavy trucks, choose 12V for light equipment, and default 380V industrial voltage for vibration motors; Verify interface consistency, confirm installation flange size, bolt hole position, and pulley specifications; According to the special design adapted to the environment, high-temperature resistant coils are selected for high-temperature environments, and waterproof and rust proof shells are selected for humid environments.
3、 Visualize troubleshooting to reduce maintenance costs
Malfunctions are inevitable during equipment operation, and quickly troubleshooting and solving problems is the key to ensuring production efficiency. We have organized a visual troubleshooting process for common faults in various series of Ningbo Naiweide motor products, with clear and easy to understand steps, suitable for frontline maintenance personnel to use.
（1） Starter failure: Focusing circuit and mechanical components
When there is no response when the switch is turned on, first check the battery voltage. If it is insufficient, charge or replace it. If the voltage is normal, then check the electromagnetic switch coil and wiring terminals; The weak starting is often related to wear of the electric brush, jamming of the one-way clutch, or short circuit of the winding. Follow the order of "checking the electric brush → one-way clutch → winding" to investigate; After starting, if the gear does not return to its original position, it is important to check the electromagnetic switch reset spring and drive gear, or replace or clean the lubrication to solve the problem.
（2） Generator Failure: Surrounding the Power Supply and Transmission System
If there is no power generation or low power generation, adjust the belt tension first, then check the rectifier and voltage regulator, and finally inspect the rotor winding; High voltage is often caused by regulator failure or rotor winding short circuit. Replace the regulator first and then check the winding; If there is abnormal noise from the generator, it is necessary to investigate the fan blades, bearings, and pulleys, and tighten, calibrate, or replace them accordingly.
（3） Vibration motor and winch motor malfunction: Locking core functional components
Insufficient excitation force of the vibration motor, first calibrate the angle of the eccentric block, then check the power supply voltage and motor speed, and finally tighten the equipment base; If the bearing overheats, it is necessary to replenish lubricating grease in a timely manner, correct the installation accuracy, and replace the compatible bearing if necessary. The winch motor has weak traction, and the focus is on checking the reducer gear, motor carbon brush, and clutch. If the drum does not brake, the brake pads and clutch mechanism need to be inspected, and foreign objects stuck on the drum shaft need to be cleaned.
