DC Motor Speed Control: In the foregoing sections we discussed the torque-speed characteristics of dc motors, bringing out the effects of armature voltage variation and field current on them. The…
Speed Torque Characteristics of DC Compound Motor: A schematic of a Speed Torque Characteristics of DC Compound Motor is shown in Fig. 1.18. There are both series and shunt fields…
Speed Torque Characteristics of Series Motor: The field winding is connected in series with the armature (Fig. 1.2(b)). The armature current and field current are the same. The operating Speed…
Speed Torque Characteristic DC Shunt Motor: The preceding discussion shows that armature voltage variation gives creeping speeds. The simple rheostatic method provides a Speed Torque Characteristic DC Shunt Motor with…
Speed Torque Characteristic of Separately Excited DC Motor: The circuit equation of a Speed Torque Characteristic of Separately Excited DC Motor whose armature, having a total of Z conÂductors, is…
Characteristics of DC Motor: DC Motors are of the rotating armature type. The armature winding is a closed winding through the commutator. The armature is supplied through the brushes which…
Electric Drive Motor: Motion control is required in large number of industrial and domestic applications like transportation systems, rolling mills, paper machines, textile mills, machine tools, fans, pumps, robots, washing…
A Simple Electric Motor: Variable speed drives in the industry employ a simple electric motor as their drive motors mainly because they enjoy several specific advantages, such as overload capacity,…
