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.

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 ...

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 ...

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, ...

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 ...

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, ...

DC machines can be classified as self-excited, separately excited, permanent magnet (PM), and brushless. Self-excited machines can be further classified as shunt, series, and compound. Compound ...

Preventive maintenance maximizes uptime while controlling costs. Maintenance crews strive to reduce maintenance costs and manage their workloads more effectively. Since DC machines require more ...
