The Pfix M4288 Series variable-frequency drive (VFD) controller is a self-contained field-mountable pump and drive controller designed as a supplement or alternative to PLC-based drive and pump ...

More and more often, variable frequency drives (VFDs) are used for control of fans and compressors in HVACR systems. The benefits are well documented and industry acceptance is such that most electric ...

Motors account for at least half of the energy consumed in the U.S. Selecting the right control method for an application lets the motor run most efficiently while maximizing torque and overall ...

The LCD/VFD controller project is based on HD44870 where the control command is compatible with Matrix-Orbital’s LCD module. The controller is based on a PIC16F873 MCU and in the design, there is no ...

Adjustable or variable frequency drives — AFDs or VFDs — use rectifiers to convert ac powerline electricity into direct current. Then inductor-capacitor filters smooth its waveforms and ...

The growth of advanced computing power embedded in a growing number of devices is changing the face of automation, and variable frequency drives (VFDs) are a big part of this trend. Capable of ...

Many of us will have experimented with brushless motors, and some of us will have built our own controllers rather than using an off-the-shelf part. Doing so is a good way to understand their ...

KPM32R24T series Chips adopt a high-performance 32-bit RISC processor, maximum frequency up to 200 MHz, supports FPU and MPU, and the performance of up to 250 DMPIS, embedded high-speed Flash memory ...
