This is a simple and very effective project circuit which helps to control the speed of a DC motor using pwm and microcontroller. In many applications, it is important to control the speed of DC motor ...

Speed, torque, and horsepower are three inter-related parameters in motor control. The speed of a motor, measured in revolutions per minute (rpm), defines a motor's ability to spin at a rate per unit ...

En route to getting the off-the-peg DC-51 motor speed controller to better suit my small milling machine, I had a go at working out what the circuit is. Approx circuit of DC-51 motor speed controller ...

I was planning to use the opto-coupler speed sensor as part of a motor speed control – making the motor into the VCO block in a phase-locked loop. When this technique works, using it is simple: put ...

The way we control the speed of fan motors or pump motors has tremendously changed in the past two decades with the introduction of variable-frequency drives (VFDs), aka variable-frequency controllers ...

To reap all the benefits that an electric motor drive can offer, choose one that's a perfect match for your application A speed control enables the motor to achieve maximum efficiency during all ...

Motor control centers (MCCs) were first introduced in 1937 as a way to conserve wall and/or floor space in industrial facilities. Before 1960, wall-mounted motor starters were used even if only a few ...

Choosing the right motor and VFD type depends on a variety of factors, however, it is necessary to first look at how the characteristics of a motor change when the speed is reduced —Sponsored article ...
