XIZI Elevator Door Motor PMM2.3G/5.0G: High-Efficiency Core for Door Operation

Proper Usage Methods of XIZI Elevator Door Motor PMM2.3G/5.0G

1. Installation & Commissioning

• First, cut off the elevator power supply and lock the door system to ensure the work area is safe. Remove the old door motor (if replacing) and thoroughly clean the installation base on the elevator door frame, removing dust, oil stains, and debris to ensure a stable mounting surface.
• Accurately place the PMM2.3G/5.0G on the installation base, aligning it with the fixed holes. Fix the motor firmly using matching screws provided by Nanjing Zhuye Elevatorparts. The tightening torque must comply with XIZI’s technical requirements (typically 4–6 N·m) to avoid loose installation caused by long-term vibration or damage to the motor shell.
• Wiring connection: Strictly follow the wiring diagram provided by Nanjing Zhuye Elevatorparts (tailored for PMM2.3G/5.0G) and XIZI’s door control system guidelines. Connect the motor’s power wires and signal wires to the corresponding terminals of the door controller. Ensure all connections are tight and the wire insulation layer is intact to prevent short circuits. Pay special attention to the correspondence between signal lines and controller pins—incorrect wiring may cause motor reversal or burnout. Nanjing Zhuye’s technical team offers remote guidance for complex wiring scenarios.
• Post-installation commissioning: Restore the elevator power supply and enter the door system’s parameter setting interface. Confirm that the motor is recognized normally by the controller. Operate the elevator door in inspection mode to test the opening and closing actions: verify that the door runs smoothly without jitter, the speed meets the set standard (adjustable via the controller), and the motor stops accurately at the fully open/closed positions. Measure the operating noise and current to ensure they are within the standard range. If abnormalities such as jitter, abnormal noise, or inaccurate positioning occur, recheck the installation and wiring and adjust promptly.

2. Daily Operation & Routine Inspection

• During daily patrols, observe the motor’s operating status when the elevator door opens and closes. Abnormal phenomena such as excessive noise, harsh friction sounds, slow operation, or unresponsive door actions indicate potential motor faults.
• Weekly visual inspection and cleaning: Use a dry, lint-free cloth to gently wipe the motor surface and cooling vents, removing dust and debris to ensure good heat dissipation. Check the motor’s fixing screws, wiring terminals, and power lines for looseness, oxidation, or damage. Retighten loose screws and clean oxidized terminals with a professional contact cleaner in a timely manner.
• Periodically monitor key operating parameters: Use a multimeter to detect the motor’s operating current (during door opening and closing) and ensure it remains within the range specified in XIZI’s technical manual. Abnormal current fluctuations may indicate issues such as motor overload or internal winding damage.

3. Regular Maintenance

• Every 3 months, conduct a comprehensive inspection of the motor’s installation status and transmission components (e.g., gears, belts connected to the door system). Check if the motor is displaced due to vibration and adjust the fixing screws if needed. Inspect the transmission parts for wear and apply professional lubricant (recommended by Nanjing Zhuye Elevatorparts) to ensure smooth power transmission.
• Every 6 months, perform a full performance test: Measure the motor’s power output, noise level, and operating temperature under full load. Verify that the motor’s speed regulation is accurate and that there is no obvious speed deviation during door opening and closing. Check the insulation performance of the windings using an insulation resistance tester to avoid short circuit risks.
• Annually, arrange professional maintenance with Nanjing Zhuye Elevatorparts’ certified technical team. Disassemble the motor to inspect internal components (including permanent magnets, windings, and bearings), remove internal dust and debris with specialized tools, and replace aging parts (e.g., bearings, seals) with genuine XIZI replacements. This service ensures the motor maintains factory-level performance and reliability.

Recommended Replacement Cycle of XIZI Elevator Door Motor PMM2.3G/5.0G

1. Standard Replacement Cycle

2. Scenario-Based Cycle Adjustment

• Harsh Operating Environments: For elevators in high-humidity coastal regions, high-dust construction sites, unventilated high-temperature machine rooms, or public facilities with extremely high passenger flow (e.g., subway stations, large hospitals), the replacement cycle should be shortened to6–8 years. Harsh conditions accelerate permanent magnet demagnetization, winding corrosion, and bearing wear, significantly reducing the motor’s reliability and service life.
• Low-Frequency Use Scenarios: For elevators with low usage frequency (e.g., villa elevators, small office buildings with less than 3,000 monthly rides) and stable operating environments, the replacement cycle can be appropriately extended to 10–12 years—provided a professional inspection by Nanjing Zhuye Elevatorparts confirms that the motor’s power output, noise level, and structural integrity are intact.

3. Immediate Replacement Conditions

• The motor fails to start or drives the door to operate abnormally (e.g., slow speed, jitter, reversal), and the fault cannot be resolved after checking wiring, power supply, and controller settings.
• The motor emits excessive noise (exceeding 70dB) or abnormal friction sounds during operation, indicating severe internal component wear or damage.
• The motor’s operating current is persistently abnormal (exceeding 120% of the rated current) or the winding insulation resistance is lower than 1MΩ, posing short circuit or burnout risks.
• The motor fails the annual performance test, and key indicators (power output, speed regulation accuracy, noise) cannot be restored to the standard range even after maintenance.
