Recently, I found an interesting fan motor module in a web shop and grabbed a couple of them for nothing. At the heart of the module is an eight-pin L9110 DC motor control chip from ASIC (www.asic.net ...

Sometimes you come across useful little devices on the internet. TK take the HW-687 DC motor controller for a spin, and does a bit of reverse engineering to tell us how it works.

The OEM module features exceptional motor control properties and also contains very fast digital current control bandwidth capabilities enabling peak DC motor current (and therefore torque) control.

The new I/O module controls stepper motors with Modbus/TCP, Ethernet/IP or PROFINET interface to host PC, PLC or PAC.

[Davide Gironi] shows us how to implement a sensorless brushless DC motor controller (sensorless BLDC) using an ATmega8 microcontroller. In order to control a BLDC motor you need to know its ...

Toshiba’s Hall sensorless sine-wave drive three-phase brushless DC motor control pre-driver IC helps reduce vibration and noise of high-speed motors.

You may be surprised that the half-bridge driver uses a pair of N-channel devices, not a symmetric P and N arrangement, as you might use to drive a low-power DC motor.

Containing two high-side and two low-side drivers, the device can control a single H-bridge powering one bidirectional DC motor or two half-bridges for two unidirectional motors.
