Regulatory compliance
All our overspeed governors comply with the strictest standards and regulations, ensuring your elevator system is always in line with legal and safety requirements.
Types of Elevator Overspeed Governor
Centrifugal Overspeed Governor
This type of overspeed governor uses centrifugal force to trigger the safety mechanism when the elevator is moving at a speed above its preset limit. As the speed increases, the flyweights or fly balls swing outward due to the centrifugal force. This outward movement causes the elevator to stop. If the speed decreases, the flyweights move inward, resetting the system for normal operation.
Inertia Overspeed Governor
This type of overspeed governor uses the inertia of weight, typically an assembly of flyballs or flyweights instead of a centrifugal force. As the speed increases, the inertia of the flyweight assembly causes it to shift position to slow down the elevator or stop it.
Working Principle of Elevator Overspeed Governor
The governor consists of a centrifugal mechanism with weighted levers attached to a rotating shaft. As the elevator speed increases, centrifugal force pushes the levers outward. When the speed reaches the overspeed threshold, the levers engage a trigger mechanism, which:
- Locks the governor's sheave, stopping the rope connected to the safety tongs.
- Pulls the tongs' activation cable, causing the tongs to grip the guide rails and halt the car.

Elevator Door Machine Motor
High Precision: Encoder resolution of 1000+ pulses per revolution ensures door position accuracy within ±1mm.
Low Noise: Brushless design eliminates mechanical friction, reducing operation noise to ≤50dB (quieter than a normal conversation).
Durability: Rated for 1 million+ door cycles (equivalent to 10+ years of use) with minimal maintenance.
Energy Efficiency: BLDC motors consume 20–30% less power than traditional AC motors, aligning with green building standards.
Common Types of Elevator Door Machine Motor
Brushless DC motor (BLDC)
Brushless DC motors are widely used in modern elevators due to their high efficiency, low noise and long life. This type of motor usually uses a closed-loop control system to achieve precise speed control and position control. In terms of technical parameters, it is necessary to pay attention to indicators such as rated voltage, current, speed, and torque.
Stepper motor
Stepper motors adjust the speed by controlling the pulse frequency and are suitable for application scenarios that require frequent starting and stopping. Although its efficiency is lower than that of brushless DC motors, stepper motors have a simple structure and low cost. For certain types of elevators, stepper motors may be a more economical choice.
AC asynchronous motor
AC asynchronous motors are widely used in various industrial fields due to their low cost and easy maintenance. However, in the field of elevator door motors, they are relatively less used due to their large starting current and difficulty in achieving precise position control. However, in some small or low-cost elevator projects, AC asynchronous motors still have a certain market space.
Working Principle of Elevator Door Machine Motor
Most modern door machine motors are brushless DC (BLDC) motors or AC servo motors, paired with a gearbox or belt-drive system. When a door command is received:
The motor receives a signal from the controller, activating its rotor via electromagnetic fields.
The motor's rotational motion is transmitted to the door panel via a pulley/belt or gear mechanism, moving the door linearly.
Encoders integrated into the motor monitor door position and speed, feeding data back to the controller for real-time adjustment.
