Glossary
The world of electric drives is developing rapidly. This glossary provides a clear and practical overview of key technical terms that are important for the use of electrically powered motors and their controls.
From basic terminology to specialised topics, content is explained in an understandable and compact way.
As technologies and requirements are constantly evolving, the glossary is regularly updated and expanded. This means that the most important information is always available in a compact, clear and practical format.
A drive control is an electronic system that controls the (electric) motor of a machine so that the motor can deliver the best possible performance.
An asynchronous motor is a widely used type of electric motor in which the speed of the rotor is not synchronised with the magnetic rotating field of the stator.
A brushless DC motor (BLDC) is a direct current motor that is used without carbon brushes.
CAN bus stands for Controller Area Network and is a standardised bus system, i.e. a system for data transmission between several participants via a common transmission path.
Compliance refers to adherence to standards and rules. These can be defined in laws, company guidelines and industry standards.
The Cyber Resilience Act, or CRA for short, is an EU regulation for the cybersecurity of products with digital elements. These include hardware and software products that can be connected directly or indirectly to a device or network.
Cyber security refers to the protection of computer systems, networks and data against digital attacks, misuse, theft and unauthorised access.
A DC-DC converter, also known as a DC-DC converter, is a device for converting direct voltage into another direct voltage with a different voltage level.
DIN EN 1175 is a standard for the electrical equipment of self-propelled forklifts. It sets safety requirements for the design and construction of the electrical and electronic systems.
DIN EN ISO 13849 is a safety-specific standard for the functional safety of machinery.
Embedded software refers to software that is directly optimised for the specific hardware and runs in it.
The Cyber Resilience Act, or CRA for short, is an EU regulation for the cybersecurity of products with digital elements. These include hardware and software products that can be connected directly or indirectly to a device or network.
Functional safety is the term used to describe the process of ensuring that a system works safely or switches off even if an error occurs.
A rectifier is a device for converting AC voltage into DC voltage. A rectifier is a power converter, just like DC-DC converters or inverters.
An I/O module is a component of automation technology. I/O stands for input and output.
IEC/TS 63074 is a technical specification for cyber security in conjunction with the functional safety of machines.
IEC 61508 is the international basic standard for the functional safety of electrical, electronic and programmable electronic systems.
IEC 61800-5-1 is an international safety standard for power drive systems with adjustable speed.
IEC 61800-5-2 is a standard for the functional safety of electrical drive systems. It sets requirements for the development of safe drives and integrated safety functions.
IEC 62061 is a standard for the functional safety of machines.
It concretizes functional safety requirements for safety-related control systems of machines within the framework of machine safety.
IEC 62443 is an international standard series for the cybersecurity of industrial automation and control systems (IACS). It describes requirements and procedures to better protect systems, machines, and controls against cyberattacks.
The IP protection class (ingress protection) allows systems to be categorised according to the degree of protection of electronic devices against the ingress of solid bodies or liquids.
ISO 13849 is a safety standard for machine controls. It sets requirements and a guide for the design and integration of safety-related parts of controls.
ISO 19014 is a standard for functional safety in earthmoving and mobile machinery.
ISO 25119 covers the functional safety of electrical, electronic and programmable electronic systems in tractors as well as in agricultural and forestry machinery.
ISO 26262 is the international standard for the functional safety of electrical and electronic systems in motor vehicles.
Power electronics is a field of electrical engineering that deals with the conversion, control and regulation of electrical energy.
A guide wire is a conductor laid in the roadway that flows through the current and serves as a reference for inductive vehicle guidance.
The MODBUS protocol is a communication protocol based on a so-called client/server architecture.
Motion control is an area of automation technology that involves the precise movement of machines and systems.
A motor controller is an electronic device used to control and regulate the speed, movement, direction and power of an electric motor.
NIS 2 is the European directive to strengthen the cybersecurity of network and information systems. It builds upon the protection for critical facilities in the EU and creates a more uniform framework for greater cyber resilience.
OTA stands for over the air, i.e. "wireless" or "cable-free" or literally translated "over the air".
SMT stands for Surface Mount Technology and is a process in electronics production in which electronic components are mounted on the surface of a printed circuit board.
A synchronous reluctance motor is an electric motor in which the torque in the rotor is generated exclusively by the reluctance force.
