Cummins engine auto spare parts motor C5614912 in stocked

Built as a critical component for engine startup and auxiliary system drive, this motor delivers exceptional power and torque performance. It features a 12-slot, 8-pole permanent magnet brushless design, generating a peak torque of 350N·m at startup—enabling the X15 engine (15L displacement) to crank smoothly even at -35℃ (with winterization package). The motor’s copper-wound stator (99.5% pure copper) and high-silicon steel rotor minimize energy loss, achieving an efficiency rating of ≥92%—reducing battery drain during repeated startups (common in construction or mining applications). At rated speed (3000rpm), it maintains stable power output to drive auxiliary components like the fuel preheater and coolant pump, supporting engine pre-conditioning

Engineered to endure the harsh operating conditions of heavy-duty engines, the C5614912 motor adopts a rugged structural design. The housing is precision-cast from ADC12 aluminum alloy with reinforced ribs, achieving a tensile strength of 220MPa and excellent heat dissipation. The drive gear is made of 42CrMo alloy steel, undergoing carburizing treatment to HRC 58-62 surface hardness—resisting wear during meshing with the engine’s flywheel (Cummins OE 5255604). A sealed double-row ball bearing (IP67 protection) ensures smooth rotation, with a service life of ≥150,000 startup cycles. The motor’s internal wiring uses high-temperature silicone insulation, withstanding 180℃ operating temperatures to avoid short circuits

Optimized for diverse operating environments, the motor exhibits exceptional resistance to temperature, moisture, and contaminants. It operates reliably within a temperature range of -40℃ to 125℃, adapting to frigid northern winters and high-temperature desert operations. The housing achieves an IP6K9K protection rating (per IEC 60529), completely blocking dust ingress and withstanding high-pressure, high-temperature water jets (80℃, 80-100bar)—ideal for off-road vehicles exposed to mud and rain. The electrical connector uses HNBR rubber seals and gold-plated pins, ensuring corrosion resistance (passing 2000-hour neutral salt spray testing) and reliable signal transmission even in saline-alkali coastal areas

The C5614912 motor is designed for energy savings and long-term cost reduction. Its brushless design eliminates brush wear, reducing maintenance frequency by 70% compared to brushed motors—avoiding costly replacements every 50,000km. The high efficiency (≥92%) reduces battery load, extending battery service life by 30% and lowering replacement costs. For fleet operators, the motor’s reliable startup performance minimizes downtime caused by failed startups (a common issue with low-quality motors, costing $500+ per hour in delayed deliveries). As a genuine Cummins part, it ensures compatibility with the original electrical system, avoiding voltage mismatches that damage the ECU. Backed by a 2-year/200,000km warranty, it provides predictable maintenance costs and reliable performance for heavy-duty applications
