Variable speed control of a compressor motor significantly reduces both the peak and average energy consumption. However, since the standards for air conditioners require a reduction in the seasonal ...

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 ...

Variable speed drives (VSDs), sometimes also known as variable frequency drives, are electronic devices used to regulate the speed of an ac induction motor. Electric motors consume approximately 25% ...

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 ...

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 Collaborative Working Principle of Variable Frequency Power Supply and Motor According to the asynchronous motor speed ...

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 ...

When implementing cooling solutions for electronic equipment, system designers are confronted with a complex set of variables. The cooling requirements are typically dynamic, and ambient temperatures ...

Pitch-controlled variable-speed horizontal-axis wind turbines (HAWTs) are increasingly being investigated for use in electrical power production. The governing equations of HAWTs are expensive to ...
