This document discusses electrical drives. It defines an electrical drive as a system that uses an electric motor to control motion for various industrial processes. The key components of an electrical drive system are a power source, power modulator, controller, motor, sensing unit, and mechanical load. The power source provides energy, typically from a 3-phase AC supply. The power modulator interfaces the motor to the power source and provides adjustable voltage, current and frequency. Common types of power modulators include controlled rectifiers, inverters, AC voltage regulators, DC choppers, and cycloconverters. Electrical drives offer advantages like flexible control, easy starting and braking, wide speed and torque ranges, and no exhaust emissions.

2. What is drive
 System employed for motion controlled are
called drive.
 So we say when a systems employed for
motion controlled then such system are called
drives.
 And what that drives system employees an
electrical motors for creating some motion
electrically is known as electrical drive.

3.  An electrical drive can be defined as an
electromechanical energy tp impact motion to
different machines and mechanisms for various kinds
of process control.
 Generally a drive system is basically has a
mechanical load a transmission sysytem and prime
mover may be I.C engine,stteam engine.

4. Advantages
 Flexiable control characterstics.
 Startinof g and breaking is easy and simple.
 Provide a wide range of torques over a wide
range of speed (both ac and dc motor)
 Availabilty of wide range of electrical power
 Works to almost may any type of enviromental
conditions.
 No exhaust gases emitted.
 Can be started and acceleration at very short
time

sysytem

6. Component of electrical drive
 Power source
 Power modulator
 Controller
 Motor
 Sensing unit
 Mechanical load

7. Power source
 The power source provides the energy to the
drive system it may be dc or ac very low power
drivers are generally feel from single phase
sources rest of the drives is powered from a 3
phase source low and medium power motors
ared fed from a 400vsupply for higher rating
motors may be rated 3.3kv, 6.6kv and 11kv

8. Power modulator
 The converter intefaces the motor with the
power source and provides motor with
adjustable voltage, current and frequencey
during transient provide such as starting
breaking and speed reversal.
Types of modulator
 Controlled rectifier
 Inverter
 Ac volttage regulator
 Dc chopper
 Cyclo cnverter.
