Frequency inverter technology is used in Variable Voltage Variable Frequency (VVVF) Lift Drives, which control input voltage and frequency throughout the journey while using much less current during acceleration and deceleration.
The PLC and VVVF control system for an elevator are the subject of the utility model. A comprehensive automatic control system for an elevator, the utility model consists of a programmable controller (PLC) with the best technology available, a signal processing module, a frequency converter with an IGBT pipe and vector control functionality, and an energy bleeder.
In addition to having conventional control capabilities, the utility model also provides fault automatic diagnostics, fault tolerant control, and communication control (intelligent control) capabilities.
Small volume, excellent technology, high intelligence, strong versatility, low failure rate, good pleasant feeling, and energy conservation are benefits of the utility model. The utility model is appropriate for the technical advancement of older elevators and the synchronised batch production of the elevator manufacturing facility.
The utility model applies to a particular type of elevator automatic control device that uses a Programmable Logic Controller and various AC voltage adjusting frequency adjusting speed adjusting equipment, also known as the VVVF speed controlling equipment.
The use of PLC machines on elevators is currently extremely widespread, but is primarily limited to the pairing of PLC machines with ACVV speed regulation and the pairing of PLC machines with double speed control.
Additionally, because multinomial control technology is involved, the combination of a PLC machine with a VVVF is currently unreported.
The Global Elevator VVVF Drive market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
The Jade Machine Roomless Geared Elevator has an integrated controller for optimal dependability and a power-efficient machine roomless arrangement on the top floor.
The faultless variable-voltage/variable-frequency (VVVF) drive intelligently modifies speed to reduce heat and mechanical strains, enhancing overall performance and lifetime. What could be better than being promoted by the best.
Propulsion inverters (also known as VVVF inverters) are the control mechanisms that change the power supply of the train into a form that may be used to drive the traction motors. These inverters convert incoming DC power to
AC power and regulate how much power is provided (voltage and frequency) in response to factors like the train’s speed and other factors. Additionally, as the train slows down, these inverters have the ability to regenerate power from the motors.
For a lift to draw significantly less current during acceleration and deceleration, variable voltage variable frequency (VVVF) lift drives are utilised to modulate motor speed and torque throughout the lift’s travel.
Stannah observed that three elevators’ VVVF drive units frequently failed. As a result, the elevator stopped functioning, making the station inaccessible to anyone using strollers or other mobility aids.
Depending on the availability and size of the required replacement part, the lift may not operate for one or two days when the drive unit fails.
