The first type of motor built is still in widespread use In the late 1800s, several inventors built the first working motors, which used direct current (DC) power. After the invention of the induction ...

Allegro Microsystems, LLC releases a new high current integrated DC motor drive IC, the A5950. Allegro’s A5950 is designed for PWM control of DC motors and capable of peak output currents up to ±3 A.

Industrial applications use direct current motors because the speed-torque relationship can be varied to almost any useful form -- for both motor and regeneration applications in either direction of ...

Systems that have controlled parameters and closed-loop feedback mechanisms are generally more robust and less susceptible to failure. For example, vehicle engines regularly use temperature sensors ...

DC motors may not be the wave of the future, but they certainly have a secure place in today’s workplace (see DC Isn’t Dead). Therefore, it’s worthwhile for electrical professionals to take a look at ...

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, ...

Brushless dc (BLDC) motors are widely used in industrial and home applications, such as in HVAC blowers, because of their efficiency and cost advantage. Furthermore, sensorless control of BLDC motors ...

Running a brushed motor in muddy or dusty environments takes a toll on controllers, with both heavy back EMF and high stall currents. This explains one of the challenge in Europe’s Hacky Racer series, ...
