What is a wound rotor motor?
A wound rotor motor is a variation of the three-phase induction motor, designed to provide high starting torque for loads with high inertia, while requiring very low current. Wound rotor motors are also referred to as “slip ring motors.” The stator of a wound rotor motor is the same as a typical induction motor, but […]
What is linear behavior for DC motors?
When the term “linear behavior” is used to describe a system, it implies that the system’s output is directly proportional to the input. Unlike their wound-field counterparts, permanent magnet DC (PMDC) motors exhibit linear behavior. The use of permanent magnets means PMDC motors don’t need separate field excitation, and therefore, don’t experience the electrical losses […]
More Beckhoff PC-based controllers earn Microsoft Azure certification
To provide plants, factories and machine builders with even more system-integrated solutions for Industrial Internet of Things (IIoT), Beckhoff Automation has announced Microsoft Azure™ certification for the C6015 Industrial PC (IPC) and CX5140 Embedded PC. All certified devices from Beckhoff can be found in the Microsoft “Azure Certified for IoT” device catalog, providing customers with […]
Short-length inductive proximity sensors allow detection in tight spaces
When working with applications in spindles, grippers, and robotics, space is typically very tight. Unfortunately, that fact doesn’t eliminate the need for automation. If anything, it increases it. These ever-shrinking spaces can create enormous stresses on standard proximity sensors. As a result, manufacturers and users of automated machinery are always requesting greater miniaturization and higher […]
What are auto-tuning methods for servo drives?
Tuning a servo system is a complex and iterative process. It typically requires tuning multiple control loops, each with its own gains (proportional, integral, and/or derivative) to be adjusted. In addition, tuning a servo drive usually requires adjustments to additional parameters including acceleration and velocity feed-forward gains and filters to reduce oscillations. While manual tuning […]

Designer 2.0 has many new features added to improve programming efficiency. A new dashboard allows easy navigation to important features and functions … … but one of the more popular additions is […]
Traction motors and steering motors and drives for electric vehicles — Custom ABM Drives designs
ABM traction drive systems for electric vehicles are available as bevel gearboxes, helical gearboxes and hub wheel drives. All drive types have outstanding efficiencies and quietness. High static wheel loads are possible with compact design gearboxes. Typical applications include forklifts, pallet trucks and sweeper-scrubbers that need sophisticated drive technology with high output at low energy consumption. ABM motor […]
Precision limit switches — new line from AutomationDirect
AutomationDirect has added a new line of high precision limit/position switches from Metrol. Traditional limit switches and even electronic proximity sensors are limited in terms of accuracy and repeatability. These cost-effective, ultra-precise mechanical limit switches have repeatability down to 10, 5, 3, and even 0.5µm (µm) depending on the specific model. Along with their high […]
