Product details

1. Product Overview

• Core Function:

Drives the radiator cooling fan for excavators (e.g., Hitachi ZX450 series), regulating hydraulic oil or engine temperature via variable-speed control to prevent system overheating.

• Brand Background:

Parker Hannifin, a global leader in hydraulic and pneumatic technologies, is renowned for its high-reliability fan motors designed for harsh environments in construction and mining equipment.

• Typical Applications:

• Hitachi ZX450-3/ZX450-6 hydraulic excavators

• Compatibility with Komatsu, Caterpillar, and other equivalent models (interface dimensions must be verified).

3. Structure and Operating Principle

• Components:

• BLDC Motor: High-efficiency, low-maintenance design with integrated Hall sensors for speed feedback.

• Planetary Gearbox: Reduces speed and increases torque (typical ratio: 5:1).

• Electronic Control Module (ECM): Adjusts PWM duty cycle based on ECU commands.

• Cooling Fins: Aluminum fin structure for enhanced motor self-cooling.

• Operating Logic:

1. Temperature sensors detect hydraulic oil/engine heat.

2. ECU sends target speed signals via CAN bus to the fan motor ECM.

3. ECM modulates PWM duty cycle to adjust motor voltage for stepless speed control.

4. Fan speed correlates linearly with temperature (e.g., 50°C → 1,000 RPM; 80°C → 2,200 RPM).

4. Common Failures and Diagnostics

【表格】

Symptom Potential Causes Diagnostic Methods Solutions

Fan inoperative Power failure, ECM damage, seized motor Measure 24V input, check CAN signal Replace fuse/ECM/motor

Irregular speed PWM signal loss, sensor failure, gear wear Use oscilloscope for PWM waveform, test sensors Repair wiring/replace sensors/gearbox

Excessive noise Bearing failure, blade deformation, gear wear Manually rotate shaft for anomalies, check blade balance Replace bearings/blades/gear set

Overheat trip Poor cooling, overload, ECM fault Inspect fin blockage, monitor current fluctuations Clear airflow/reduce load/update ECM firmware

------

5. Maintenance and Upkeep

• Daily Checks:

• Clean cooling fins every 500 hours to prevent dust buildup.

• Verify electrical terminal tightness every 250 hours to avoid arcing.

• Monitor operating temperature (via ECU diagnostics, normal ≤85°C).

• Periodic Replacements:

• Bearing grease every 2,000 hours: Use Parker-recommended high-temperature lithium grease.

• Carbon brushes (for brushed motors): Replace when worn to 1/3 of original length (not applicable for BLDC).

• Seals every 5,000 hours: Prevent oil contamination.

• Storage Requirements:

• Store vertically at -20°C to +60°C with humidity ≤85%.

• Run motor for 10 minutes under no-load before long-term storage to distribute lubricant.
