DC Motor Braking Methods: The need for electric braking was explained earlier, the motor works as a generator developing a negative torque which opposes the motion. Three types of DC Motor…
Types of DC Motor: The commonly used Types of DC Motor are shown in Fig. 5.1. In a separately excited motor, the field and armature voltages can be controlled independent…
Heating and Cooling Curves of Electrical Drives: An accurate prediction of Heating and Cooling Curves of Electrical Drives rise inside an electrical motor is very difficult owing to complex geometrical…
Load Equalisation in Electrical Drives: Load Equalisation in Electrical Drives - In some drive applications, load torque fluctuates widely within short intervals of time. For example, in pressing machines a…
Motor Design Parameters: Different parts of a load may be coupled through different mechanisms, such as gears, V-belts and crankshaft. These parts may have different speeds and different types of…
Four Quadrant Operation of Motor Drive: For consideration of Four Quadrant Operation of Motor Drive, it is useful to establish suitable conventions about the signs of torque and speed. Motor…
Television Horizontal Deflection Circuit: The function performed by these circuits is exactly the same as already described for the vertical deflection circuits. There are some practical differences. The major one…
Vertical Deflection Circuit in TV: The Vertical Deflection Circuit in TV include the vertical oscillator and amplifier for vertical scanning at 60 Hz and a similar horizontal arrangement for scanning…
