Elevator Door Operator Motor YCT73-3.5: Core Electromagnetic Speed-Regulating Component from Nanjing Zhuye Elevatorparts
The elevator door operator motor YCT73-3.5 is a high-performance electromagnetic speed-regulating motor, serving as the core drive unit for elevator door systems. It provides stable and adjustable power to control the smooth opening and closing of car and landing doors, with speed regulation precision directly affecting passenger experience and door system safety. Exclusively supplied by Nanjing Zhuye Elevatorparts, this motor is designed for medium-load passenger and freight elevators. Compliant with international standards such as EN 81-1 and national standard GB/T 7060-2015, it features a rated power of 3.5kW, wide speed regulation range (120-1200r/min), and reliable torque output. Widely compatible with mainstream elevator brands including Thyssen, Otis, and domestic brands like Hengda and Jiajie, it is widely applied in residential buildings, commercial complexes, and industrial workshops.
Nanjing Zhuye Elevatorparts adheres to stringent quality control standards, and the YCT73-3.5 door operator motor is a testament to this commitment. Each motor undergoes rigorous pre-delivery testing, including excitation coil resistance verification, high-low temperature (-25℃ to 85℃) resistance tests, noise level detection (≤60dB), and insulation resistance testing (≥2MΩ with 500V megohmmeter). The motor adopts a high-quality copper winding and silicon steel sheet core to enhance efficiency and reduce energy consumption. The shell is made of cast aluminum with excellent heat dissipation, and the bearing is equipped with high-temperature resistant lubricating grease for long-term operation. It has built-in overcurrent, overheating, and undervoltage protection functions, and the speed regulator supports stepless speed adjustment to ensure smooth door movement.
Usage Guide for Elevator Door Operator Motor YCT73-3.5
Proper installation, wiring, debugging, and daily maintenance are vital to maximizing the performance and service life of the YCT73-3.5 motor. Nanjing Zhuye Elevatorparts strongly recommends that only certified elevator maintenance technicians perform these operations. Before installation, verify that the motor model matches the door operator and control system. For detailed wiring diagrams and speed regulator parameter settings, refer to the product manual or contact our technical support team. Note: Cut off the main power supply before operation, wear protective gear, and ensure the installation environment is dry and dust-free.
1. Pre-Installation Preparation
First, cut off the elevator’s main power supply and lock the switch, then move the car to a middle floor for safe operation. Prepare professional tools: torque wrench, screwdrivers, 500V megohmmeter, level ruler, wire strippers, and insulation tape. Clean the door operator bracket installation position to remove dust and oil stains. Inspect the motor for external damage (cracked shell, loose wiring terminal) and test insulation resistance and winding continuity. Check matching components like belts, pulleys, and speed regulators for wear, replacing damaged parts in advance.
2. Installation & Wiring
Fix the YCT73-3.5 motor on the door operator bracket with high-strength bolts, using a level ruler to ensure horizontal installation (tolerance ±1mm). Tighten bolts according to the torque specification (M8 thread: 8-10N·m) to avoid vibration-induced loosening. Follow the wiring diagram to connect the three-phase power wires, excitation coil wires, and speed feedback wires to the controller. Ensure the wiring terminal is firmly fixed and the wire stripping length is 6-8mm. Separate power wires and signal wires to reduce interference, and install the protective cover after wiring. Adjust belt tension to 3-5mm deflection under 5N force for smooth power transmission.
3. Debugging & Daily Maintenance After installation, restore power and debug. Set the speed regulator parameters (acceleration/deceleration time, rated speed) to match the elevator door system, and run the motor under no-load first to check for abnormal noise or overheating. Then perform load testing: ensure the door opens/closes smoothly, with accurate positioning at full open/close positions. For daily maintenance, follow TSG T5002—2017 regulations: Clean the motor shell and cooling vents monthly; inspect bolts, wiring, and bearing temperature. Quarterly, check insulation resistance, replace bearing lubricating grease, and adjust belt tension. For harsh environments, increase inspection frequency to twice a month and spray anti-rust agent on metal parts.
Replacement Cycle of Elevator Door Operator Motor YCT73-3.5
The replacement cycle of the YCT73-3.5 motor depends on usage frequency, operating environment, and maintenance quality. Under normal conditions—12-24 hours of daily operation, regular maintenance, and moderate traffic—Nanjing Zhuye Elevatorparts recommends a replacement cycle of 4-6 years. This cycle is formulated based on field test data and T_CEA 0061—2025 standards, considering factors such as excitation coil aging, bearing wear, and insulation performance degradation.
For elevators in high-traffic areas (airports, subway stations) or harsh environments (high humidity, heavy dust), the replacement cycle should be shortened to 3-4 years. High-frequency operation accelerates winding and bearing wear, while harsh environments cause corrosion and insulation damage. For low-usage elevators (villas, small offices), proper maintenance can extend the cycle to 6-7 years. Motors over 5 years old require semi-annual professional inspections by Nanjing Zhuye Elevatorparts technicians to assess performance.
Replace the motor immediately if: It makes abnormal noise/vibration or overheats frequently (surface temperature >85℃); insulation resistance drops below 0.5MΩ; the excitation coil is damaged or the speed regulation fails; it causes frequent door system faults; the shell is severely corroded; it fails annual safety inspections. Use genuine YCT73-3.5 motors from Nanjing Zhuye Elevatorparts to ensure compatibility and safety.

2. Installation & Wiring
Align the ANCT-ES1-TF1 interface board with the mounting bracket inside the control cabinet and fix it with screws. Note that the tightening torque should be appropriate (20-30 N·m recommended) to avoid damaging the PCB substrate. According to the wiring diagram provided by Nanjing Zhuye Elevatorparts, connect the power wires (DC 24V) and signal wires (CAN bus lines) to the corresponding terminals of the elevator main controller and peripheral devices. The wire stripping length should be controlled at 6-8mm, and terminals must be tightened firmly to prevent poor contact. Separate power wires and signal wires to reduce electromagnetic interference, and use cable ties to organize the wires neatly. After wiring, install the protective cover and double-check for wrong or missing connections—incorrect wiring may cause protocol mismatch or communication failure.

Replacement Cycle of Elevator Interface Board ANCT-ES1-TF1
The replacement cycle of the ANCT-ES1-TF1 interface board depends on usage frequency, operating environment, and maintenance quality. Under normal conditions—12-24 hours of daily operation, stable voltage, clean control cabinet environment, and regular maintenance—Nanjing Zhuye Elevatorparts recommends a replacement cycle of 6-8 years. This cycle is formulated based on extensive field test data and GB/T31821—2015 standards, fully considering key factors such as aging of electronic components, attenuation of communication performance, and incompatibility with upgraded control systems.
For elevators in high-traffic areas (e.g., airports, subway stations with daily operation over 20 hours) or harsh environments (high humidity, heavy dust, frequent voltage fluctuations), the replacement cycle should be shortened to 4-6 years. High-frequency data transmission accelerates component wear, and harsh environments easily cause circuit corrosion and signal interference. For low-usage elevators (e.g., villas, small offices with daily operation <8 hours), proper maintenance can extend the cycle to 8-10 years. However, Nanjing Zhuye Elevatorparts’ technicians should conduct semi-annual comprehensive inspections on boards over 7 years old, including communication performance and protocol compatibility tests.
Regardless of service life, replace the ANCT-ES1-TF1 board immediately if: Communication failures occur frequently and cannot be repaired; the board fails to transmit signals accurately, leading to abnormal operation of elevator components; indicator lights are dim, flickering, or non-functional; the board is severely corroded or cracked; the board is incompatible with the upgraded elevator control system; it fails to pass annual safety inspections.
