You can salvage some nice motors out of optical drives but they can be tricky to control. That’s because brushless DC motors require carefully timed signals used in a process called Electronic ...

The DC motor speed control project is intended to manage the pace of a DC motor by means of an 8051 sequence micro-controller. The pace of DC motor is straightforwardly relative to the voltage ...

The current limit circuit (see diagram) compares this voltage to an adjustable negative voltage using an op-amp wired as a comparator – unlike many op-amps, LM324 op-amps can be used as comparators ...

Smart Motor Devices has improved the controller BMD-20DIN by expanding ways to control speed of DC motor – new device is now available at the industrial market ...

Because the module has two L9110 chips, it can drive two independent DC motors. Surprisingly, the L9110 dual-driver module works with DC voltages from 2.5 to 12 V, caters continuous current of 800 mA, ...

With a BLDC motor and a good controller, not only can you easily control speed and direction, but also torque and slip. Also, to call these “brushless DC” motors is wrong. These are three ...

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 ...

So that any speed droop when loading the motor is due to this resistance. The trick, apparently, is to measure the internal dc resistance of the motor – ether with an ohm meter, or though applying a ...

To read Part 5, go to V/fopen-loop control in DC brushless DC motors. To read Part 4: go to 180 degree modulation for brushless motorcontrol. To read Part 3, go to Prosand cons of sensor vs sensorless ...
