Step-by-Step Usage Guide for Elevator Door Motor 150ST-24 MDPM-431823-01

To maximize the performance and service life of the Elevator Door Motor 150ST-24 MDPM-431823-01, and to ensure the safe and stable operation of the elevator door system, strictly follow the professional guidelines provided by Nanjing Zhuye Elevatorparts for installation, debugging, and maintenance:

1. Professional Installation & Wiring

Installation must be conducted by certified elevator technicians proficient in heavy-duty elevator door operator systems. Prior to installation, refer to the compatibility manual provided by Nanjing Zhuye Elevatorparts to confirm that the 150ST-24 MDPM-431823-01 is compatible with the target elevator’s door operator model, power supply parameters, and control system. The installation steps are as follows:

Safety Preparation: Cut off the elevator’s main power supply and the dedicated power supply for the door operator system. Lock the power switch and place a “Maintenance in Progress” warning sign to prevent accidental power-on. Clean the motor mounting position on the door operator bracket to remove dust, oil stains, and debris that may affect installation accuracy or heat dissipation.
Motor Installation: Fix the 150ST-24 MDPM-431823-01 motor to the dedicated mounting bracket using high-strength bolts provided by Nanjing Zhuye Elevatorparts. Ensure the motor is installed horizontally (horizontal deviation ≤ 1mm) and that its output shaft is coaxial with the door operator’s reducer input shaft (coaxiality deviation ≤ 0.1mm) to avoid abnormal wear and vibration. Connect the motor output shaft to the reducer via a high-torque flexible coupling, ensuring a tight fit without slipping or looseness.
Wiring Operation: In accordance with the elevator door operator wiring diagram and the 150ST-24 MDPM-431823-01 user manual, connect the motor’s power cables and the electromagnetic brake’s control cables to the corresponding interfaces of the door operator controller. Confirm the correct phase sequence to avoid reverse motor rotation; use shielded cables for control signals and connect the shield layer to the dedicated grounding terminal to enhance anti-interference performance. Verify that the motor’s rated voltage (AC 380V), frequency (50/60Hz), and power match the controller’s output parameters. Tighten all terminals to ensure reliable contact and good insulation.
Post-Installation Debugging: Restore the power supply and switch the elevator to inspection mode. Adjust the motor’s speed, acceleration, and deceleration parameters via the controller to match the elevator’s door opening/closing requirements (standard opening speed: 0.9–1.3m/s, closing speed: 0.7–1.0m/s). Test the door operation to ensure smooth movement without jitter, sticking, or excessive noise. Confirm the electromagnetic brake functions normally—doors should stop immediately when blocked and remain firmly locked when the motor is powered off. Conduct a 2-hour continuous operation test to check the motor’s surface temperature (normal temperature ≤ 95℃) and speed stability under full load.

2. Daily Operation & Routine Maintenance

Regular inspection and maintenance are crucial to early fault detection and ensuring the long-term stable operation of the 150ST-24 MDPM-431823-01 motor. Maintenance personnel should integrate the following checks into their daily patrol routines:

Daily Visual Inspection: During door operator patrols, check the motor’s external condition. Ensure the cast aluminum housing is free of deformation, cracks, or corrosion; the power and control cables are intact without aging, wear, or loose connections; the mounting bolts and coupling are tight. Observe the door operation for abnormalities (e.g., slow movement, uneven speed, unusual noise) that may indicate motor faults.
Weekly Performance Check: Use a clamp meter to measure the motor’s three-phase input current, ensuring the three phases are balanced (current difference ≤ 10%) and within the rated range. Measure the motor’s surface temperature after peak operation hours to confirm no abnormal overheating. Check the coupling’s tightness and the reducer’s lubrication status, adding the special lubricant recommended by Nanjing Zhuye Elevatorparts if necessary.
Monthly Cleaning & Maintenance: Clean the motor housing and heat dissipation fins with a soft, dry cloth or air blower to remove dust and debris, ensuring effective heat dissipation. Inspect the terminal block for oxidation or loose connections, cleaning or tightening as needed. Verify the functionality of the electromagnetic brake by testing the door’s holding force when powered off and checking the brake’s wear status.

Recommended Replacement Cycle for Elevator Door Motor 150ST-24 MDPM-431823-01

As a core drive component enduring long-term high-load operation, frequent start-stop cycles, and environmental erosion (humidity, dust, vibration in the door operator), the 150ST-24 MDPM-431823-01 elevator door motor has a specified service life. Timely replacement is critical to avoiding faults such as reduced speed control accuracy, insufficient torque, abnormal noise, or complete motor failure—issues that may cause door operation failure, stuck doors, or disrupt elevator service, affecting passenger safety and experience.

1. Standard Replacement Cycle

Under normal operating conditions (elevator daily operation time 12–24 hours, daily door opening/closing cycles ≥ 2000, environment temperature -10–60℃, humidity 10%–95%), the recommended replacement cycle for the 150ST-24 MDPM-431823-01 is 5–7 years. This cycle is determined based on Nanjing Zhuye Elevatorparts’ long-term field operation data, motor component aging tests, and global user feedback on heavy-duty elevator door systems.

2. Adjustments for Special Scenarios

Harsh Environments & High-Traffic Scenarios: For elevators in high-humidity coastal areas (salt spray corrosion), high-dust industrial sites, or ultra-high-traffic locations (e.g., large airports, central shopping malls) with daily door cycles ≥ 4000, the replacement cycle should be shortened to 3–4 years. Harsh conditions and frequent use accelerate winding aging, bearing wear, and electromagnetic brake degradation, significantly reducing the motor’s reliability.
Low-Frequency Use Scenarios: For elevators with low usage frequency (e.g., high-end villa elevators, small office buildings with daily operation time < 8 hours) and stable environments, the replacement cycle can be extended to 7–8 years—only if Nanjing Zhuye Elevatorparts’ professional technicians conduct an inspection and confirm that the motor’s speed control performance, torque output, and brake function meet the original factory standards.

3. Immediate Replacement Conditions

Replace the 150ST-24 MDPM-431823-01 immediately if any of the following issues occur, regardless of its service life:

Insufficient torque causes slow door operation, difficulty opening heavy doors, or frequent stalling—fault persists after controller adjustment and reducer maintenance.
Speed control fails or is inaccurate, leading to uneven door movement, excessive opening/closing speed, or failure to decelerate at the end of the stroke, posing safety risks.
Abnormal noise (e.g., sharp friction, heavy vibration) or rapid overheating (surface temperature > 120℃ within 15 minutes) indicates internal bearing damage or winding failure.
The electromagnetic brake fails, causing the door to slide freely when the motor is powered off, or the motor fails to start/operate intermittently due to brake jamming.

In conclusion, the Elevator Door Motor 150ST-24 MDPM-431823-01 supplied by Nanjing Zhuye Elevatorparts is a high-quality, reliable drive component tailored for modern heavy-duty elevator door systems.
