Elevator Door Motor YSM-100-26H: Reliable Power Core from Nanjing Zhuye Elevatorparts

Step-by-Step Usage Guide for Elevator Door Motor YSM-100-26H

1. Professional Installation & Wiring

• Safety Preparation: Cut off the elevator’s main power supply and the dedicated power supply of the door system. Fix the elevator door panel to a safe position using a temporary support frame to prevent accidental movement during motor installation. Clean the motor mounting bracket (usually on the car top or landing door frame) to remove dust, oil stains, and debris that may affect installation stability.
• Motor Installation: Fix the YSM-100-26H door motor to the dedicated mounting bracket using high-strength bolts provided by Nanjing Zhuye Elevatorparts. Ensure the motor is installed horizontally (horizontal deviation ≤ 2°) and the output shaft is aligned with the door system’s transmission mechanism (e.g., synchronous belt pulley, gearbox) to avoid eccentric load. Install the coupling or transmission belt between the motor output shaft and the door system, ensuring proper tension (neither too tight nor too loose).
• Wiring Operation: According to the elevator door system wiring diagram, connect the motor’s power terminal (rated voltage consistent with the door controller) and control signal terminal (connected to the door controller’s output interface). Ensure correct polarity, tight wiring, and reliable insulation—use heat-shrinkable tubes for wiring joints to avoid short circuits. Clearly mark each wire as guided by Nanjing Zhuye’s manual for future maintenance and troubleshooting.
• Post-Installation Debugging: Restore the power supply and switch the elevator to inspection mode. Debug the motor’s operation parameters (e.g., door opening/closing speed, acceleration/deceleration time) through the door controller, following Nanjing Zhuye’s recommended parameter ranges. Test the door opening/closing function: confirm the motor operates smoothly without jamming, abnormal noise, or sudden speed changes. Verify the motor’s protection functions: simulate overload conditions to ensure the motor stops working automatically and triggers a fault alarm.

2. Daily Operation & Routine Inspection

• Daily Visual Inspection: During shaft patrols, check the external condition of the YSM-100-26H door motor. Ensure the aluminum alloy housing is free of cracks, deformation, or discoloration (a sign of overheating); the cooling fan (if equipped) operates normally; the wiring terminals are tight without looseness, oxidation, or burning marks; the transmission belt (if applicable) is free of wear, cracking, or slipping.
• Weekly Functional Check: Operate the elevator in normal mode to test the motor’s performance during peak hours. Use a tachometer to measure the door opening/closing speed, ensuring it is within the set range. Check the motor’s surface temperature after continuous operation (should not exceed 80℃) to avoid overheating damage. Listen for abnormal noises (e.g., squeaking, rattling) during motor operation, which may indicate bearing wear or transmission problems.
• Monthly Electrical Parameter Detection: Use a multimeter to detect the motor’s input voltage, current, and insulation resistance (insulation resistance ≥ 10MΩ) to ensure electrical performance is normal. Check the door controller’s fault records for any motor-related errors, and troubleshoot in a timely manner if any are found.

3. Regular Maintenance Schedule

• Quarterly Maintenance: Disconnect the power supply and remove the motor’s end cover (if necessary). Clean the motor’s housing, cooling fan, and wiring terminals with a professional electrical cleaner to remove dust and debris. Apply a small amount of special lubricant (recommended by Nanjing Zhuye Elevatorparts) to the motor’s bearing and transmission parts to ensure smooth operation. Check the tightness of the mounting bolts and retighten if necessary.
• Semi-Annual Performance Test: Conduct a comprehensive performance test, including power output, speed regulation accuracy, noise level, and protection function response time. Simulate extreme operating conditions (e.g., voltage fluctuation, low-temperature environment) to verify the motor’s stable operation. For elevators in high-traffic areas (e.g., shopping malls, airports), increase the test frequency to once every 3 months.
• Annual Professional Overhaul: Arrange a professional inspection with Nanjing Zhuye Elevatorparts’ certified technical team. Disassemble the motor (if necessary) to inspect the internal components (e.g., copper winding, rotor, bearing) for wear or damage. Replace aging components (e.g., bearing, cooling fan, capacitor) with genuine parts. Recalibrate the motor’s operation parameters to meet the original factory standards and the elevator’s actual operating needs.

Recommended Replacement Cycle for Elevator Door Motor YSM-100-26H

1. Standard Replacement Cycle

2. Adjustments for Special Scenarios

• Harsh Environments: For elevators in high-humidity coastal areas (salt spray corrosion), high-dust construction sites, or locations with frequent voltage fluctuations (e.g., industrial zones), the replacement cycle should be shortened to 3–4 years. Harsh conditions accelerate winding insulation aging, bearing corrosion, and housing damage, significantly reducing the motor’s reliability.
• Low-Frequency Use Scenarios: For elevators with low usage frequency (e.g., villa elevators, small office buildings with daily operation time < 8 hours) and stable electrical environments, the replacement cycle can be extended to6–7 years—only if Nanjing Zhuye’s professional inspection confirms the motor’s power output, speed regulation accuracy, and electrical performance are intact (consistent with original factory standards).

3. Immediate Replacement Conditions

• The motor fails to provide sufficient power, leading to slow door opening/closing, difficulty in opening heavy doors, or frequent stalling during operation.
• The motor overheats frequently (surface temperature > 90℃) or triggers overload protection alarms, even after maintenance and debugging.
• The motor has obvious mechanical failures, such as bearing jamming, rotor damage, or winding burnout (accompanied by burning marks or odor), and cannot work normally even after repair.
• The motor’s speed regulation accuracy is severely reduced, leading to unstable door operation, obvious impact when opening/closing, or failure to meet the elevator’s safety operation requirements.
