Prior to the advent of the adjustable-speed drive (ASD), the polyphase induction motor operated as a constant-speed motor. Figure 1 shows the well-known torque and current curves versus speed for the ...

Farnell and Freescale have created a development kit for low voltage motor drives. Called MagniV, it is a single board variable speed drive for brushless DC (BLDC) motors and permanent magnet ...

“A very basic variable speed drive will save between 10 and 20 percent energy compared to a conventional induction-type motor,” said Rice. “A more advanced technology, or ECM [electronically ...

Sales of dishwashers have skyrocketed in India during the Covid-19 lockdown. Power Integrations’ BridgeSwitch half-bridge motor driver ICs are well-suited for single-phase motor drive applications ...

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 ...

SAN JOSE, Calif.--(BUSINESS WIRE)--Power Integrations (Nasdaq: POWI), the leader in high-voltage integrated circuits for energy-efficient power conversion, today released its Motor-Expert software, an ...

THE first edition of this work appeared in 1904. Since then remarkable advances have been made in electrical engineering. A foremost place in this progress must be given to electric motors, and more ...

You can divide the world of electronic motor drives, which control the speed, torque, direction, and resulting horsepower of a motor, into two categories: ac and dc. An ac drive controls ac induction ...

Description: This model can be specified with either a Vari-Green® EC (electronically commutated) motor with a speed control dial for single-phase motor applications or a NEMA premium efficiency motor ...

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 ...
