Starting Method of Induction Motor: Transient processes involved with the Starting Method of Induction Motor in a variable speed drive require a detailed study. The electric motor and connected load…
Characteristics of Synchronous Motor: Characteristics of Synchronous Motor are constant speed motors. The speed of the motor is decided by the number of poles and frequency. Compared to an induction…
Torque Speed Characteristics of Induction Motor: From Eq. 1.27 it can be observed that the maximum torque is independent of rotor resistance. However, the slip at which the maximum torque…
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 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…
Temperature Controls using an Analog Electronic Controller: A Temperature Controls scheme using an Analog Electronic Controller of Fig. 21.14 is as shown in Fig. 21.16. The temperature setting, derived from a slide…
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,…
