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- ...

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 ...

Model VSM-CA3 modulates the speed of motors in fancoil units, fan-powered VAV terminal units, fan filter units, and other air-moving devices. The controller provides modulating control of AC induction ...

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 ...

The DynaMotor motor/drive is a combination of an ac motor and variable-speed controller that provides 11 lb-ft of torque at 160 rpm. The unit does not use an inverter and connects directly to an ac ...

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 ...

Demand is growing for appliances such as washing machines, refrigerators, and air conditioners to help improve domestic energy efficiency. Moving from conventional fixed-speed motors to variable-speed ...

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 ...

Vector Control, also known as Field Oriented Control or FOC is an AC motor control scheme that enables fine-grained control ...

RS, a high-service global product and service solutions provider for industrial customers, offers Schneider Electric's ...

Utility power plant generators are usually designed for a power factor (PF) of .8 to .9. If demand-side PF is lower than the designed PF, the generator current will rise above the equipment's rated ...
