Types of electrical drives pdf
Electric motors drive most machines Every machine consists of four different components, shown in the diagram. These components are energy control, the motor, transmission and the working machine. Together, the first three components comprise the so called “drive system”. This drive system can transform a given type of energy, usually electrical, into mechanical energy, which is then used
Types of electric vehicles. There are three main types of electric vehicles (EVs), classed by the degree that electricity is used as their energy source.
The difficulty of the classification of electric drives is caused by the fact that the drive systems are dedicated to specific motor types. Here an overview is given about the trends of the electrical drive systems based on some fundamental features.

Power electronics is the application of solid-state electronics to the control and conversion of electric power. The first high power electronic devices were mercury-arc valves . In modern systems the conversion is performed with semiconductor switching devices such as diodes , thyristors and transistors , pioneered by R. D. Middlebrook and others beginning in the 1950s.
The following three major types of hybrid systems are being used in the hybrid vehicles currently on the market: 1) SERIES HYBRID SYSTEM The engine drives a generator, and an electric motor uses this generated electricity to drive the wheels. This is called a series hybrid system because the power flows to the wheels in series, i.e., the engine power and the motor power are in series. A series

Chapter 2 Actuators and Drive Systems Actuators are one of the key components contained in a robotic system. A robot has many degrees of freedom, each of which is a servoed joint generating desired motion. We begin with basic actuator characteristics and drive amplifiers to understand behavior of servoed joints. Most of today’s robotic systems are powered by electric servomotors. Therefore
