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 ...

To reap all the benefits that an electric motor drive can offer, choose one that's a perfect match for your application A speed control enables the motor to achieve maximum efficiency during all ...

Variable frequency drives convert ac power to dc and then reshape that current to control ac motors. All types control speed by varying current frequency, but one subtype — flux vector drives — uses ...

Once the control method of choice only in high-performance industrial ac-servo drives, FOC (field-oriented control) is finding its way into lower end industrial and many appliance applications with ...

For the PDF version of this article, click here. More than 80% of the motors bought each year continue to be low-cost single-phase ac motors. Because these motors are not very efficient when ...

Choosing the right motor and VFD type depends on a variety of factors, however, it is necessary to first look at how the characteristics of a motor change when the speed is reduced —Sponsored article ...

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- ...

Motors account for at least half of the energy consumed in the U.S. Selecting the right control method for an application lets the motor run most efficiently while maximizing torque and overall ...

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 ...

Both AC and DC motors convert electrical energy into mechanical energy used to power various appliances. For example, refrigerators, drills, blenders, and dryers all use electrical motors to generate ...

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 ...
