IV. Product Features
Permanent Magnet Reduction Design: Permanent magnet poles + parallel shaft reduction, small size, high efficiency; power density increased by over 15% compared with traditional series motors.
High Reliability: Optimized carbon brush and commutator, suitable for frequent start-stop; over 90% success rate at -30℃ low-temperature start.
Perfect Matching: 9-tooth pinion engages smoothly with V19/4G24 engine flywheel, stable start, low noise.
Cost-Effective: Lower cost than foreign brands (e.g., Bosch) with equivalent performance.
V. Operating Instructions
Single starting time ≤ 5 seconds, interval ≥ 2 minutes to avoid overheating damage.
Secure wiring required; cable cross-section ≥ 25mm² to prevent voltage drop under high current.
Ensure proper bolt torque during installation; gear engagement clearance 0.5–1.0mm to avoid noise or gear damage.
