Ebook Electric Motor Control provides beginning students with a practical approach to motor control. The textbook discusses electrical and mechanical components and how they are connected to control different types of motors. Many different types of control circuit and illustrations are discussed. The text contains a wealth of practical information that will apply to almost any industrial application.
Typical dynamic responses are also shown. The motor is initially at standstill and
at no load when a step command in speed is applied; when steady-state conditions are
reached, a reversal of speed is commanded followed by a step load application.
The system is highly nonlinear due to the introduction of saturation needed to limit
both the current delivered and the voltage applied to the motor.
The control system for a star delta contactor is
The star contactor and delta contactor are interlocked
relative to each other with a ‘either - or’ condition.
Switching from ‘star’ to ‘delta’ is done automatically
by means of a time relay.
In the circuit above, the star contactor is energised
first, then the mains contactor. Circuits in which the
mains contactor is energised first, followed by the star
contactor, are also common.
Individuals with an interest in learning about electric motors and how they are controlled
A simple understanding of magnetics is assumed Topics Covered:
What is an electric motor?
What are some common types of electric motors?
How do these electric motors work?
How these motors are controlled.
The use of a combustion engine to motivate a car has been questioned in recent times due
to the increasing concern of warming. As a result of this, the concept of driving
a car with an electric engine has become of particular interest. Dr. Geoff Walker and his
PhD students are working on the creation of the Universitys own electric car.
This thesis project is focused on deriving a control scheme to drive an induction machine
that could be applied to the electric car.
The L297 Stepper Motor Controller IC generates four phase drive signals for two phase bipolar and four phase unipolar step motors in microcomputercontrolled applications. The motor can be driven in half step, normal and wawe drive modes and onchip PWM
The amount of knowledge an electrician must possess
to be able to install and troubleshoot control systems in
today’s industry has increased dramatically in recent
years. A continuous influx of improved control components
allows engineers and electricians to design and
install even more sophisticated and complex control
systems. Industrial Motor Control presents the solidstate
devices common in an industrial environment.
Most research in robotics centers on the control and equations of motion for
multiple link and multiple degree-of-freedom armed, legged, or propelled systems. A
great amount of effort is expended to plot exacting paths for systems built from
commercially available motors and motor controllers. Deficiencies in component and
subsystem performance are often undetected until the device is well past the initial design
This application note discusses the steps of developing several controllers for brushless motors. We cover sensored,
sensorless, open loop, and closed loop design. There is even a controller with independent voltage and speed controls so you can discover your motor’s characteristics empirically.
