When powering AC motors, the electrical supply can be at full power to run at full speed or at variable power to run at variable speed. Applications with varying loads benefit from the variable speed ...

The principle of vector control of electrical drives is based on the control of both the magnitude and the phase of each phase current and voltage. For as long as this type of control considers the ...

Once the control method of choice only in high-performance industrial ac-servo drives, FOC (field-oriented control) is finding its way into lower end industrial and many appliance applications with ...

Direct torque control is a motor-control method for ac drives that accurately regulates motor speed and torque without encoder feedback from the motor shaft. Eliminating encoders can simplify ...

Enclosures can be either integrated or barrier formats. The Altivar 71 ac drive is designed for constant torque and heavy-duty applications at 150% current limit for motors from 1 to 40 hp at 208 to ...

The Durapulse GS20 Series of next generation high-performance variable frequency drives provides many standard and advanced functions in a compact reduced size unit. The new GS20X series of AC drives ...

In today’s fast-paced industrial landscape, efficiency, sustainability, and performance are essential. One technology driving this change is low-power AC drive technology. Variable frequency drives ...

Speed control of an AC motor requires a three phase supply that can vary both voltage and frequency. Such a supply creates a variable speed rotating field in the stator that allows the rotor to spin ...

The SEC-AC-SMLC Multi-Axis Controller is a fully-integrated control solution for motion control, logic and I/O needs, providing hardware and software building blocks that are engineered to easily plug ...
