Original Quality Assurance
Strictly following Caterpillar's original production specifications, each 390-0788 motor undergoes factory level insulation performance testing, torque output testing, and high and low temperature resistance experiments to ensure that core parameters such as voltage and speed are fully matched with original accessories. As the core component of the device startup system, its original quality can avoid failures such as weak startup and motor burnout caused by compatibility issues with accessories, ensuring the long-term stable operation of the startup system.
High specification material technology
The motor housing is made of high-strength gray cast iron (HT250) cast in one piece, with excellent impact and vibration resistance performance; The rotor coil is made of 99.9% pure copper material, which has high conductivity and low heat loss; The stator core is made of stacked high silicon steel sheets, effectively reducing hysteresis losses. The surface is treated with electrophoretic rust prevention, which can resist the erosion of humid and dusty environments in mining, oil fields, and other scenes. Compared with ordinary motors, the service life is extended by more than 40%.
Efficient startup performance
Built in high-power permanent magnet motor, with a starting torque of 280N · m and a stable speed of 3200r/min, can easily drive the C18/C27 engine crankshaft to run; Equipped with a low-temperature preheating device, it can still achieve successful start-up in a low-temperature environment of -30 ℃, solving the problem of equipment start-up in cold regions. The motor adopts an IP54 protection level design, with outstanding dustproof and waterproof performance, avoiding internal component wear caused by impurities entering.
Range of compatible models
Specially developed for Caterpillar C18 ACERT and C27 ACERT diesel engines, compatible with heavy equipment such as CAT 773G mining dump trucks, 785C mining trucks, 3516B generator sets, and CAT 6060 excavators. Widely applicable to mining, large-scale infrastructure, port loading and unloading, and emergency power generation scenarios, it can be directly replaced and installed without modification, and its adaptability covers multiple types of heavy-duty operation needs.
Protection of Use Value
Stable starting performance can reduce mechanical shock during engine start-up and extend the service life of engine components such as crankshafts and bearings; Efficient motor design reduces energy consumption during start-up, coupled with low-temperature rapid start-up capability, reduces equipment preheating time, and improves operational efficiency; Reduce maintenance frequency caused by startup failures, reduce maintenance downtime losses by 15%, and optimize equipment operating costs.
