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 ...

DC Motor Applications provides a comprehensive overview of DC motors and their uses in industry. DC motors generally consist of an armature, a commutator, brushes, and field windings. DC motors may be ...

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 ...

To sense high dc currents, designers typically use shunt resistors or Hall-Effect-based current sensors. But shunt resistors are plagued by Joule (I2R) losses and the need to open the circuit where ...

Infolytica Corporation announces MotorSolve v4.1 is now available. This latest update introduces the new DCM module for brushed DC and universal motors. It uses the same powerful automated finite ...
