Allegro Microsystems developed and launched the A4938 last 2010. This device is a three-phase brushless DC (BLDC) motor pre-driver that supplies direct, high-current gate drive of an all N-channel ...

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 ...

The MLX81300 is the first member of a family of LIN motor drivers. For positioning applications the MLX81300 can control 3 phase steppers with low noise microstepping, as well as DC motors.

Infineon has added gate drive charge pumps to keep motor drive mosfets working properly in a three-phase motor controller that works across 5.5 to 60V, and up to 1.5A (diagram below). Called 6EDL7141, ...

Matching drive to motor is essential to gain the best combination of torque, speed, and efficiency. Selecting the right drive is essential to getting the best performance and efficiency from an ...

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) ...

One of the hidden complications of upgrading grain drying and handling systems is providing enough electricity to power the new larger electric motors. Electric motors that are larger than 15 hp ...

The topic of motors and motor control techniques is wide and varied. Part one of this two-part article will cover the principles of alternating-current (AC) motor operation and control. Part two will ...
