The conventional universal motors used in many kitchen and garage appliances, power tools and other small household appliances typically lack accurate speed control. Basically, the motor is either in ...

The way we control the speed of fan motors or pump motors has tremendously changed in the past two decades with the introduction of variable-frequency drives (VFDs), aka variable-frequency controllers ...

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 ...

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 ...

Motors are driving demand for electricity, accounting for about half of the electricity we consume, according to the Electric Power Research Institute (EPRI). Many of these motors are found throughout ...

The topic of motors and motor control techniques is wide and varied. Part one of this two-part article will cover the principles of alternating-current (AC) motor operation and control. Part two will ...

The MDrive34Plus2 Speed Control combines a motor, driver, and encoder, and includes a programmable digital oscillator for accurate, variable-speed control. The device uses a NEMA-Size-34 brushless ...

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 ...

What is a variable frequency drive? Heating, ventilation, and air conditioning systems' air supply used to be constant volume into a space. Now a variable air volume control is being used to provide ...
