With the increasing use of variable-frequency drives (VFDs), there is increased generation of electrical currents on shaft motors, causing electrical damage to bearings. Manufacturers and end users ...

Industry demand has spurred the use of small precision motors and linear actuators. Choose wisely. A few characteristics of dc motors maintain linear relationships that allow for very predictable ...

Brushless-dc motors are taking center stage in medical-equipment design because they last twice as long a competing technologies. • Sensorless brushless-dc-drives have evolved to a point where they ...

DC motors possess linear relationships that allow for very predictable operation. For instance, if enough voltage is applied across the terminals of a DC motor, the output shaft will spin at a rate ...

The BLH speed control package is composed of a brushless DC motor and a 24VDC compact driver board. The RoHS-compliant BLH series encompasses four models at 15, 30, 50 and 100 watts output. The BLH ...

Oriental Motor of Japan has created brush-less dc motors for automated guided vehicles (AGVs) and autonomous mobile robots. BLV-R motors, which are the R type of the BLV series, come in 100W (1/8hp) ...

If the source of supply is d.c. (for example in a battery vehicle or a rapid transit system) a chopper-type converter is usually employed. The basic operation of a single-switch chopper was discussed ...
