Brushed DC motors are widely used in applications ranging from toys to push-button adjustable car seats. Brushed DC motors are inexpensive, easy to drive, and are readily available in all sizes and ...

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 ...

A brushless DC (BLDC) electric motor is likened to a motor with brushes, but turned “inside-out.” A BLDC motor has a rotor with permanent magnets and the stator contains the windings. Older motors ...

Sizing a DC motor to accurately meet a set of requirements can be a thankless task. Having to choose between brush-type or brushless motors can complicate the selection. Even experienced designers may ...

Thermal dissipation is a byproduct of many modern semiconductor devices and has improved with low-leakage, low-power CMOS processes. But as designers cram more processing power into smaller spaces, ...
