AutomationDirect's Practical Guide to Variable Frequency Drives (VFDs) is a practical resource for learning how to select and apply AC motor control solutions for industrial equipment. It covers core ...

To some, motor speed control is somewhat of a mystical science, a science that causes motors and machines to sometimes operate in unexpected ways. Over 30 years ago, AC drives were considered "new ...

Global demand for both energy and water conservation is having a tremendous impact on the home appliance market. The regulatory standards and recommendations are redefining a new generation of energy- ...

For example, consider the United States, where the incoming line frequency is usually 60 Hz at 120 V. If an engineer has an AC motor with two poles (a pole pair motor), then the motor's synchronous ...

AC motors are commonly paired with variable frequency drives (VFDs) which control motor speed by regulating the frequency of the supplied voltage. Depending on the application and level of speed ...

Out of the total energy used in the U.S. in a day, a large portion goes to motors. Electric motors in everything from escalators to air conditioners to production machinery consume a tremendous amount ...

Note: This specialization requires purchase of a hardware kit in order to apply your knowledge and skill with real world tools. The hardware will be used to complete the lab exercises across the four ...

AC drives or Variable frequency drives control speed, torque, acceleration, deceleration, and rotation direction of AC motors. AC drives save energy by tailoring the power delivered to meet the actual ...

Early incarnations of the electric motor first appeared in the 1740s through the work of Scottish Benedictine monk and scientist, Andrew Gordon. Other scientists such as Michael Faraday and Joseph ...
