Allegro MicroSystems developed the A4931 which was released since 2007. The A4931 is a full three-phase brushless DC motor predriver. This device provides a direct voltage output up to 38 V and ...

The DRV8313 provides three individually controllable half-H-bridge drivers. It is intended to drive a three-phase brushless dc motor, though it can also be used to drive solenoids or other loads. Each ...

Selection of replacement motors is usually straightforward if the ratings are equivalent. Sometimes, however, a different type of motor is necessary or desirable. For success in these cases, it is ...

KAWASAKI, Japan--(BUSINESS WIRE)--Toshiba Electronic Devices & Storage Corporation ("Toshiba") has today started to provide engineering samples of a gate driver [1] IC, "TB9084FTG,” for three-phase ...

Compressor overheating is one of the industry's most serious field problems today. Compressor overheating is usually caused by high compression ratios. High compression ratios can be caused by a ...

Having both 3-phase and single-phase loads can be challenging when trying to balance the voltages at a facility. It’s possible that during a facilities operation, one phase can be lightly loaded ...

The flux-oriented control (FOC) is a commonly used technique for three-phase electric motor control application. Here, the applied voltage pattern is defined using the space vector modulation (SVM) ...

A miniaturized driver IC developed by Toshiba controls three-phase dc brushless motors in electric fan applications. The TB6585AFTG’s integrated PWM controller circuit generates a sine wave, which ...

What You’ll Learn: The origins of Permanent Magnet Brushless DC motors (PMDC). How the efficiency of electric motors increases as you increase the number of phases. How to optimally control stators as ...

For motor applications, engineers have several options at their disposal. Typically, engineers can choose between direct-current (DC) or alternating-current (AC) motors. Machine Design has covered the ...
