H Bridge configuration is commonly used in electrical applications where the load needs to be driven in either direction. A typical H-Bridge structure is shown below; The current flows through the ...

Many applications using miniature brushed DC motors require motors to operate at more than one load point or through specific load cycles. Running a motor at usable load points requires a variable, ...

Maxon Precision Motor's newly released DC servo motor controller, the ESCON 50/5 OEM module. This mini OEM plug in module is a 4 quadrant Pulse Width Modulated (PWM) servo motor controller that can ...

Pulse width modulation is a form of signal communication that transposes a signal from analog to digital form. Analog signals with changing amplitude and frequency pass through a comparator and are ...

Last spring, in response to California's recent electricity shortage, Governor Gray Davis signed a bill into law that provides financial incentives for upgrades that improve the efficiency of motor ...

Sensor-less brushless dc motors do not have to be hard to drive, claims Allegro MicroSystems. “Start-up and run commutation can be customised for individual motors and loads by adjusting a few default ...

There are a lot of cheap Chinese CNC machines out there with okay mechanics and terrible electronics. The bearings aren’t complete crap, but the spindle of these CNC machines is a standalone PWM ...

I have been trying to fix a little old milling machine I bought (and here), and needed a replacement motor controller. It is a Clarke DCM10, a variant of Sieg’s X1, sometimes knows as a ‘micro mill’.

Years ago my pal Steve Titus wanted to experiment with some drone rotor designs. He needed a simple motor controller that could operate from 8V to 12V and deliver amperes of current to a DC motor used ...
