In this exciting video, we dive into the world of controlling high voltage DC motors and the intricate process of designing a ...

The thyristor d.c. drive remains an important speed-controlled industrial drive, especially where the higher maintenance cost associated with the d.c. motor brushes (c.f. induction motor) is tolerable ...

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 ...

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 ...

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 ...

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 ...

[Mike] has put up a great video on his [SmallEngineMechanic] YouTube Channel about a tool we don’t see very often these days. He’s using an armature growler (YouTube link) to test the armature from a ...

To successfully integrate the drive into the system, the controller must provide full functionality for motor control. The more functions the drive itself can implement, the fewer add-ons and ...
