A 22.38 kW, 440-V, 4-pole wave-wound d.c. shunt motor has 840 armature conductors and 140 commutator segments. Its full-load efficiency is 88% and the shunt field current is 1.8 A. If brushes are ...

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 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 ...

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 ...

The OMDC-125 Series variable-speed dc control controls the speed of PM, shunt wound, and universal motors. The CE-compliant control features dual voltage (120/240 Vac or 24/36 Vac), adjustable ...
