The ZXBM1021Q20TC (621-ZXBM1021Q20TC) is a single-phase, variable speed, motor control pre-driver featuring built-in Hall amplifier and an integrated current control. It operates up to 18 V with speed ...

“A bunch of things are coming together.” That's how V Sukumar, a senior applications manager for Fairchild Semiconductor, begins a discussion of trends in motor control for the white-goods market.

Speed, torque, and horsepower are three inter-related parameters in motor control. The speed of a motor, measured in revolutions per minute (rpm), defines a motor's ability to spin at a rate per unit ...

In hydronic heating and cooling systems, circulator pumps move water or refrigerant throughout a closed-loop system in order to transfer energy from the source to the point of need. While older ...

The Multi-Contactor Starter (MCS) controls 2-speed, 2-winding and 2-speed, 1-winding re-connectable motors. The starter features a built-in timer and control functions that reduce the number of ...

Today, much of the electricity on the planet is consumed by inefficient electric motors from a bygone era. It is estimated that over 50% of all electricity is directed at powering motors that feature ...

Single- and three-phase alternating current (AC) motor speed can be controlled by controlling the frequency of the voltage coming to it. Motor speed has a lot to do with the capacity of refrigeration ...

It is interesting to look at figures from the Energy Information Administration about where energy gets consumed in our economy. These figures reveal that industrial uses account for 31% of all energy ...

Upgrades that included a constant-torque flux-vector variable-speed motor let a pre-1912 vintage stamping press handle modern production duties. The rebuilt press was refurbished with new ac-drive ...

Variable speed drives are transforming modern irrigation by shifting control from valves to pump speed. Instead of running motors at full capacity and throttling flow, the drives adjust motor speed to ...

Choosing the right motor and VFD type depends on a variety of factors; however, it is necessary to analyze how the motor changes when the speed is reduced. The experts at eMotors Direct outline ...

Upgrades that included a constant torque flux vector variable-speed motor let a pre-1912-vintage stamping press handle modern production duties. The cast-iron press, salvaged for $80, weighed about ...
