[Frank Herrmann] had an interesting idea to turn a geared DC motor into a servo motor assembly, but with a stepper motor-like interface. By stacking some small PCBs behind the motor body, it was ...

An H-bridge (full-bridge) driver is quite popular in driving loads such as brushed DC motors and it is widely used in robotics and industry. The main advantages of using an H-bridge driver are high ...

In this article we will discuss how to build a powerful DC motor driver that can be controlled using a microcontroller like an Arduino or a Raspberry Pi, or even a standalone PWM generator chip. DC ...

Driving a brushless DC (gimbal) motor can be a pain in the transistors. [Ignas] has written up a nice article not only explaining how to do just this with an Arduino, but also explaining a little bit ...

Seeing this Toshiba motor drive, my first thought was ‘what a neat chip for pairing with an Arduino’ as it combines operation across 1.8 to 7V with up to 4A drive – so that is Li-ion batteries, 5V USB ...

Infineon has released a family of H-bridge driver ICs for small brushed dc motors in vehicles, that include hardware for ISO26262-level functional safety. Called the BTM90xx family, they are intended ...

How does a dc motor operate, and what's the impact of back EMF? Difference between continuous and stall current. How is current regulation applied in dc motor drivers? Oftentimes, the motor driver and ...

The A3918 is a full-bridge dc-motor driver capable of 1-A continuous output and 2.5 to 9-V operating voltage. An internal PWM current reference lets users select the peak chop current with a resistor ...
