Green Technology : Elevator Drives
First application of electric engine for elevators applied by German inventor Werner von Siemens, In 1880. Many advances have been done since then. Increasing motor and drive performance and reducing power consumption and size has brought to elevator industry by development on new technologies.
Electronic control systems introduced in the lifts since 1960s, and have increased the ride comfortably and have allowed faster installation and configuration.

Because of various demand in the industry for vast kind of motors used in elevators and changes in voltage and power supply frequency by electricity distribution companies, solid state elevators drives play an important role in reliability and safety of elevators. There is two main groups of engines :

In any technical application, both in industry and in civil field, there is always a special attention towards energy saving. In the 80s, DC motors were abandoned, because during the braking phase they harvest energy from the network. Every new technology will be supported only if it decreases energy consumption.
Due to importance of advanced elevators direct drive technology, Saba Barque Tavan Electric Systems Inc have focused on research and development of these kind of electric drives since 2012. Providing high quality products for international markets have set the company aim and they want to reach that by attending to the quality of power control equipment. They have always focused on consumer satisfaction as their main asset.

Certificates and Standards
Working in high-tech industry need highly specific standards and certificates. SBT Inc features to obtain these requirements are as follow:

According to above requirements the company have awarded following standards and certifications:

Pardis Technology Park Infrastructure
One of the main requirement of a knowledge based economy is supporting infrastructures such as science and technology park. Important role of these kind of infrastructures on all stages of a product or service development is clear. Due to the fact that they help decision maker to distribute limited resources and converge them to the aim directly and thus this infrastructures help resource proficiency increase.
Pardis Tech Park (PTP), is main hub of innovation and technology in Iran and mange to facilitate movement toward knowledge based economy. More than 250 knowledge and technology based firms have been supported by PTP under vice-presidency of science and technology of Iran

The D8 Technology Exchange Network secretariat placed in Pardis Technology Park, are welcomed collaboration and cooperation to increase synergy between D8 countries science and technology sectors.
Saba Barque Tavan Inc have been supported by Pardis Tech Park as one the best R&D center and Technology Park in the MENA.
