One of the difficult challenges that designers may face is to isolateprecision analog signals in an extremely noisy environment. A goodexample is monitoring the motorphase current in a ...

It's hard to stay up to date when you are floating in a sea of technical jargon. However, it's imperative that engineers know the terminology associated with the areas in which they work. And that's ...

Next is the H-bridge, which resembles an H (Figure 2), which is used typically with a brushed DC motor. In addition to run, coast, and break operating modes, it can also reverse a motor. Simplified ...

Trinamic Motion Control's TMCM-0013-xA current-sense boards are lab tools designed to simplify the measurement and visualization of two-phase motor currents. The boards are well-suited for tuning a ...

A 480V, 3-phase, squirrel-cage motor is a common piece of equipment in many facilities. When sizing circuit breakers, fuses, and conductors for a general AC motor branch circuit, National Electrical ...

Renesas has announced its RX111 motor control kits. These inverter reference solution kits are designed to drive any three-phase permanent magnet synchronous motors (PMSM), also called brushless AC ...

For the PDF version of this article, click here. Traditional motor-phase-current sensing methods depend on sensors with signal bandwidths of 100 kHz or greater. Problematically, such bandwidths allow ...

Having both 3-phase and single-phase loads can be challenging when trying to balance the voltages at a facility. It’s possible that during a facilities operation, one phase can be lightly loaded ...

Isolated sigma-delta (∑-Δ)-based analogue-to-digital converters (ADCs) have become the preferred method for phase current measurement in high performance motor and servo drives. The converters have ...

Compressor overheating is one of the industry's most serious field problems today. Compressor overheating is usually caused by high compression ratios. High compression ratios can be caused by a ...
