The precise meaning of the term ‘servo’ in the context of motors and drives is difficult to pin down. Broadly speaking, if a drive incorporates ‘servo’ in its description, the implication is that it ...

If the source of supply is d.c. (for example in a battery vehicle or a rapid transit system) a chopper-type converter is usually employed. The basic operation of a single-switch chopper was discussed ...

You can divide the world of electronic motor drives into two categories: ac and dc. A motor drive controls the speed, torque, direction, and resulting horsepower of a motor. A dc drive typically ...

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 ...

DC motor drives are used in a variety of commercial and industrial applications, including rolling mills, printing presses, and elevators. When working as intended, these drives use energy more ...

Industry demand has spurred the use of small precision motors and linear actuators. Choose wisely. A few characteristics of dc motors maintain linear relationships that allow for very predictable ...

Small and powerful DC motors are critical to the development of ever more highly integrated systems. These motors are driving technology in many different sectors, from medical and laboratory ...

EPC9176 is a GaN-based three-phase inverter with a 81 x 75 mm footprint (with connector) that can operate across 20 to 80V and up to 20A (28A peak). “This voltage range and power level makes the ...

When Tesla first introduced the 3-phase alternating current (AC) induction motor in 1888, he knew that his invention was more efficient and reliable than Edison's direct current (DC) motor. However, ...

Brushless DC motors, and their associated drive electronics, tend to be expensive and complicated. [Ottoragam] was looking for a cheaper alternative and built this Brushed DC motor servo controller ...

Speed control of an AC motor requires a three phase supply that can vary both voltage and frequency. Such a supply creates a variable speed rotating field in the stator that allows the rotor to spin ...
