GTAKE provides Elevator VFD solutions for passenger and freight elevators, with dedicated Variable Frequency Drive technology designed for precise motor control, smooth acceleration and deceleration, and reliable elevator operation. The GK620E elevator dedicated AC drive combines sensorless vector control, flexible S-curve control, high starting torque, and accurate speed regulation for elevator applications.
As an experienced Variable Frequency Drive manufacturer, GTAKE develops AC drives for elevators and other industrial motor-control applications, supported by dedicated R&D capabilities, manufacturing resources, and application-specific drive technology.
An Elevator VFD (Variable Frequency Drive) is a motor control device used to regulate the speed, torque, and operating behavior of an elevator motor. By adjusting the output frequency and voltage supplied to the motor, an Elevator VFD enables controlled acceleration, deceleration, and speed regulation throughout the elevator travel cycle.
Unlike a general-purpose motor application, elevator systems require coordinated motor control to achieve smooth starting, stable low-speed operation, accurate leveling, and comfortable stopping. The drive therefore plays an important role in the overall performance of the elevator control system.
GTAKE offers both general-purpose and application-specific AC drives, including the GK620E elevator dedicated AC drive developed for passenger and freight elevator applications.
Elevator motor control requires more than simple speed adjustment. The drive needs to respond accurately to changing operating conditions while maintaining smooth movement throughout acceleration, constant-speed travel, deceleration, and stopping.
A dedicated Elevator VFD can support:
These functions allow the VFD to work as part of the elevator control system rather than simply operating the motor at a variable speed.
The Variable Frequency Drive regulates the output frequency and voltage according to the required motor operating condition. Sensorless vector control can provide more accurate motor speed and torque control than basic V/f control, making it suitable for applications that require improved dynamic response.
Elevator passengers can feel sudden changes in acceleration and deceleration. The VFD uses configurable acceleration and deceleration profiles to provide a smoother transition between different operating speeds.
GTAKE’s elevator drive supports flexible S-curve programming, helping optimize elevator acceleration and deceleration characteristics for improved ride comfort.
Elevators need sufficient motor torque when starting with different passenger or freight loads. GTAKE’s GK620E supports starting torque up to 180% at 0.25 Hz with sensorless vector control 2, providing additional torque capability for demanding starting conditions.
Accurate stopping and leveling are important for elevator operation. The drive can provide controlled low-speed operation and precise speed regulation during the final stage of travel, supporting the elevator control system in achieving consistent stopping performance.
An Elevator VFD can monitor motor operating conditions and provide protection functions against overload and other abnormal conditions. The GK620E supports 150% current for 1 minute and 180% for 10 seconds, with higher overload capability possible by selecting an appropriately oversized drive.
GTAKE’s GK620E Elevator Dedicated AC Drive is specifically designed for passenger and freight elevators used in residential buildings, shopping malls, and office buildings.
The drive supports sensorless vector control and V/f control, allowing the control mode to be selected according to the motor and application requirements. Its flexible S-curve function is designed to improve elevator ride comfort, while its control performance supports accurate speed regulation and high starting torque.

The exact drive configuration should be selected according to the elevator motor, rated power, load characteristics, control system, and installation conditions.
GTAKE Elevator VFD solutions can be applied to different elevator systems where controlled motor operation and reliable speed regulation are required.
For residential, commercial, and office buildings, the VFD helps control elevator acceleration, travel speed, deceleration, and stopping to provide smooth operation.
Freight elevators operate with different and often heavier load conditions. Appropriate VFD sizing and motor-control settings can provide the torque and overload capability required for these applications.
In residential elevators, ride comfort and controlled stopping are important factors. S-curve control and accurate speed regulation can help reduce sudden changes during elevator operation.
Shopping malls and office buildings typically require elevators to operate frequently throughout the day. A properly configured VFD provides controlled motor operation and supports reliable elevator performance.
A general-purpose VFD can control the speed and torque of an AC motor across many industrial applications. However, elevator applications have additional requirements related to acceleration, deceleration, leveling, starting torque, and passenger comfort.
For this reason, an elevator-specific drive such as the GK620E can be selected when the application requires functions and control characteristics designed specifically for elevator operation.
GTAKE also offers the GK620 general-purpose AC drive for broader industrial applications. It supports V/f and sensorless vector control and can be used for equipment including cranes, lifts, conveyors, compressors, pumps, and other motor-driven machinery.
