Yaskawa Whitepaper: The I’s and O’s of VFDs





An electric motor is an electromechanical device that converts electrical energy into mechanical energy. The reverse process of producing electrical energy from mechanical energy is performed by a generator.
The synchronous motor is defined by the fact that the rotor rotates at the same speed as the magnetic field created by the stator windings. The design of the stator is in many cases similar to that of induction motors, with distributed windings. Some manufacturers use concentric windings (in slot) which enable a more compact motor design and require less copper. The energy savings achieved by the reduced use of copper are however often eaten up by additional losses, which result from harmonics in the air gap flux caused by the construction.
The requirements for modern production plants are becoming increasingly complex. It is therefore essential that the drive technology used is the best possible solution for the task at hand.
Yaskawa is pleased to announce that Drives Technical Communications was awarded a 2019 APEX Award in the How-To Writing category for their design work on new quick setup procedures for Yaskawa’s latest generation of AC drives.
Linear servo motors contribute to improved machine functionality and performance with exceptional features such as high speed, fast acceleration, long strokes, smooth speed control, clean operation, low noise, and low maintenance.
We live in a time where variable frequency drives (VFDs) are now the standard when it comes to motor control. As they’re being installed primarily in commercial and industrial buildings, both new and old applications are reaping the benefits these intelligent devices bring. But just like all electronics, VFDs do not last forever.

Weidmüller’s scalable engineering software, u-control 2000, adapts individually to your requirements. And, the u-control is powerful, compact and fully compatible with Weidmüller’s I/O system u-remote. This article looks at what makes u-control the heart of your automation.
Programmable logic controllers (PLCs) are one of the main components of any automated system. A typical control system has inputs, outputs, controllers (i.e., PLCs), and some type of human interaction with the system, a human machine interface (HMI), for example.
