This paper presents the system concepts and describes the circuit implementation of several key features. The increasing use of high-current brushless dc (BLDC) three-phase motors puts stringent ...

Teledyne LeCroy’s MDA8000 series of motor-drive analyzers performs three-phase power-analyzer static (steady-state) calculations, dynamic three-phase power and mechanical motor analysis, and ...

One of the more popular three-phase electrical services supplied to medium-size commercial buildings is the Wye or Star configuration transformer. The name comes from the transformer’s secondary ...

ROHM provides a comprehensive lineup engineered to improve motor efficiency, enhance functionality, and reduce power consumption across a wide range of applications. Santa Clara, CA and Kyoto Japan, ...

Oriental Motor USA is proud to introduce our new three-phase standard AC motor, the KIIS Series Standard AC Motor, available in 60 W (1/12 HP) and 100 W (1/8 HP) output power. Oriental Motor USA is ...

It’s impossible to balance line-to-line voltages perfectly in three-phase circuits, so they typically differ by a few volts or more. However, if voltage unbalance exceeds 1%, it can markedly decrease ...

Allegro MicroSystems, Inc. announces a new high voltage three-phase motor driver family in a small package that minimizes board space and expands the use of inverter technology (variable speed control ...

The A3936 three-phase brushless dc motor controller/driver IC features 3-A DMOS output stages and commutation logic. The chip will operate with motor supply voltages ...

One of the hidden complications of upgrading grain drying and handling systems is providing enough electricity to power the new larger electric motors. Electric motors that are larger than 15 hp ...

Home machinists can often find great deals on used industrial equipment, and many a South Bend lathe or Bridgeport milling machine has followed someone home. Then comes the moment to plug it in, and ...
