This glossary is intended to provide a basic understanding of the technical terms and product names used in the Yaskawa presentation materials.


AC drive

Device for controlling rotation speed of motor. The motor can be controlled so that it does not rotate more than necessary, contributing to energy saving and CO2 reduction. An explanation of the AC drive can be found here.

AC servo motor

A motor essential in the field of factory automation that control the position, speed, and path of objects at high speed and with high precision. For more explanation of the servo motor, click here.


Artificial Intelligence.

Arc welding

A welding method that uses an arc discharge, an electric discharge phenomenon in air. It is characterized by linear joining and is used in various industries including the automobile industry.



In the fields of pharmaceutical development and manufacturing and biotechnology, a lot of manual work remains, especially in a severe sanitary environment. Yaskawa provides robot solutions that automate manual operations in the biomedical field while ensuring accuracy and safety.



Each of the processes that make up a factory’s production line.

Controller (Machine controller)

A device that controls various devices that perform complex movements at high speeds using servo motors and AC drives. While PLCs(Programmable Logic Controller) excel in input/output (I/O) control, while machine controllers are ideal for controlling complex movements at high speed and with high precision.


Electric instrumentation system for water and sewage

A system to realize stable and efficient operation of water supply and sewage systems by making full use of electrical instrumentation technology, information processing and communication technology. You can see examples of Yaskawa’s system construction and proposals here.

Electric system for steel plant

A system that controls blast furnace equipment, continuous casting equipment, rolling, process lines, and other equipment. High reliability is required for stable and continuous operation. You can see examples of Yaskawa’s system proposals here.

Electrical equipment for large-scale wind turbines

Electrical equipment installed on wind turbines with large generating capacity such as offshore wind power generation. Yaskawa provides generators and converters through its Finnish subsidiary “The Switch”, acquired in 2014.


A sensor that detects position and angle, essential for precise motor control.


Electric Vehicle.



Factory Automation.


Flat Panel Display. Thin display devices such as liquid crystal displays, plasma displays, and organic light-emitting diode displays.


Human collaborative robot (Cobot)

Cobot has safety sensors built into its body to ensure safety for people, and can work together while sharing space with people.
You can also see an explanation of the cobot here.


i³-Mechatronics (i cube mechatronics)

Yaskawa’s concept to integrate its mechatronics products with data application technologies to create solutions that continually improve the productivity of customers’ factories. i³ stands for the 3 steps of integrated, intelligent, and innovative that make a smart factory possible. Read more about i³-Mechatronics.

Industrial robot

Robots used to automate tasks in various industries.
You can read more about industrial robots here.


Internet of Things. By connecting goods to the Internet, new businesses and services are expected to emerge in various fields.


Matrix converter

A next-generation motor drive that solves the various problems faced by conventional drive equipment, such as the use of regenerative energy and suppression of harmonics that lead to equipment malfunction and failure, in a single unit. Yaskawa Electric is the first company in the world to commercialize this product.


This term was first coined by Yaskawa Electric in the late 1960s with the concept of combining customers’ machinery and equipment, or “Mechanism” with Yaskawa’s electrical products, or “Electronics” to achieve higher functions.


Parallel link

Unlike vertical articulated robots in general, parallel link robots have multiple mechanisms arranged in parallel. It is mainly used for high-speed transportation of lightweight parts.

PM motor

High efficiency motor using permanent magnet for rotor part. Because it cannot be driven by commercial power, a control device such as an AC drive is required.

Power conversion

Changing the magnitude of direct or alternating current or the frequency of alternating current. AC drive uses power conversion technology to convert DC power into AC of variable voltage and frequency.

PV inverter

A device that converts DC power generated by solar panels into commonly used AC power. Yaskawa supplies industrial PV inverters through its U.S. subsidiary “Solectoria”, acquired in 2014.



Abbreviation of Selective Compliance Assembly Robot Arm. Among industrial robots, it has a horizontal articulated structure and is used for automating planar work.

Social system

Systems for infrastructure facilities such as water supply and sewerage

Spot welding

A welding method that uses heat generated by the electrical resistance of metal by passing an electric current through a material to be welded held between electrode rods. It is characterized by point joints and is mainly used in the production of automobile bodies.


Vegetable factory

A plant that grows vegetables in an artificial environment where the cultivation environment is controlled. (Temperature, humidity, nutrient solution, CO2, irradiation, etc.). It enables the planned cultivation of vegetables regardless of weather conditions.



Abbreviation of digital communications equipment for consumers (From the acronyms of Computer, Communication and Consumer Electronics)
