As previously mentioned, the feedback sensors include position sensors to track the rotor’s location, current sensors to measure the motor phase currents, voltage sensors to monitor the DC bus voltage ...

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) ...

Every day engineers design products that employ single-phase induction motors. Speed control of single-phase induction motors is desirable in most motor control applications since it not only provides ...

Single-phase motors are common in many industries and can be found in blowers, pumps, fans, lathes, and numerous other types of equipment. Single-phase motor failures or malfunctions can often be ...

Open-loop current sensors have a definite price advantage over closed-loop counterparts. While you can use them in drive applications where torque accuracy isn't demanding — such as pump and fan ...

Allegro MicroSystems today announced three ICs: two analogue current sensors and a motor driver for fans. The first current sensor, ACS37630, is designed to be sat on top of a bus bar and partly ...

El Segundo, Calif., November 30, 2011—Given their capability to improve car safety, convenience and fuel efficiency, semiconductor magnetic sensors used in automotive motors will enjoy fast market ...
