In 1987, the first Mini-Z models came onto the market, small remote-controlled car models for racing fun (not only) in your own living room. Since then, the mini-RC cars in 1:24 scale and smaller, especially as ready-to-run models, have offered an inexpensive entry into sophisticated car modelling. In this book, Hans-Peter Sollik presents five selected models, from monster trucks to Formula 1 racers, showing the construction and possible uses of these smart RC cars. What is included in the usual scope of delivery, which motor, and chassis equipment can be considered, which battery technology and which remote control components, are described by the author as well as the wide range of optical and technical improvements: tuning. Anyone who wants to get to know RC car modelling and gain initial experience with miniature models, perhaps in order to switch to larger scales later, will find the right instructions in this book.

"Brushless" heißt das neue Zauberwort im RC-Modellbau: Motoren dieses Typs haben während der letzten Jahre einen wahren Siegeszug angetreten. Kein Wunder, bieten sie doch eine ganze Reihe von Vorteilen - besonders im Vergleich zu Verbrennungsmotoren, die den RC-Bereich bis in die jüngste Vergangenheit dominierten. Klare Pluspunkte für Brushless Zu den Pluspunkten zählen unter anderem die weitaus geringere Lärmentwicklung, der deutlich höhere Wirkungsgrad, die kompaktere Bauweise und das leichtere Handling. Die Brushless-Vielfalt Der richtige Einsatz eines Brushless-Motors will trotzdem gelernt sein. Schließlich gibt es mehrere Bauarten, etwa den Brushless-Innenläufer, der hauptsächlich im RC-Car-Bereich Verwendung findet. Auch die Leistungsfähigkeit des Motors wird von zahlreichen Einflussgrößen bestimmt - darunter seine spezifische Drehzahl sowie die Anzahl seiner Wicklungen und der in ihm verbauten Magnete. Alle Fragen anhand von Beispielen erläutert Ein wichtiger Aspekt ist auch der Fahrtregler, denn er steuert den Motor an und hat maßgeblichen Anteil an der Leistungsentfaltung. Wie genau wirken sich all diese Faktoren aus? Für welche Modelle ist ein bestimmter Innenläufer geeignet? Welcher Fahrtregler passt zu welchem Motor? Und wie wird er auf ihn abgestimmt? In diesem Buch finden Sie die Antworten - umfassend, verständlich und zielführend. Informationen zu Akkus und ihrer Pflege, zu Ladestationen und der Fernsteuerung runden den Inhalt ab. Damit sind Sie für den erfolgreichen Betrieb eines Brushless-Motors in RC-Cars bestens gerüstet.

In recent years, brushless DC motors and controllers have begun an unparalleled triumph in model construction and in all technical fields. This book is intended to show how a brushless motor works. The basic principle is discussed first, before all the key terms such as kV and rpm/V, operating voltage, load and idle current, torque, turns, electrical and mechanical power, losses, efficiency, etc. are explained. A brushless motor can't work without a brushless controller, it requires a three-phase AC voltage. To increase the speed properly, the controller must have information on the rotor position. This can be done by Hall sensors or directly via the motor windings. All that will be taken into account in the book.

In this report, simple, low-cost design and prototyping methods for custom brushless permanent magnet synchronous motors are explored. Three case-study motors are used to develop, illustrate and validate the methods. Two 500W hub motors are implemented in a direct-drive electric scooter. The third case study, a 10kW axial flux motor, is used to demonstrate the flexibility of the design methods. A variety of ways to predict the motor constant, which relates torque to current and speed to voltage, are presented. The predictions range from first-order DC estimates to full dynamic simulations, yielding increasingly accurate results. Ways to predict winding resistance, as well as other sources of loss in motors, are discussed in the context of the motor's overall power rating. Rapid prototyping methods for brushless motors prove to be useful in the fabrication of the case study motors. Simple no-load evaluation techniques confirm the predicted motor constants without large, expensive test equipment. Methods for brushless motor controller design and prototyping are also presented. The case study, a two channel, 1kW per channel brushless motor controller, is fully developed and used to illustrate these methods. The electrical requirements of the controller (voltage, current, frequency) influence the selection of components, such as power transistors and bus capacitors. Mechanical requirements, such as overall dimensions, heat transfer, and vibration tolerance, also play a large role in the design. With full-system prototyping in mind, the controller integrates wireless data acquisition for debugging. Field-oriented AC control is implemented on low-cost hardware using a novel modification of the standard synchronous current regulator. The controller performance is evaluated under load on two case study systems: On the direct-drive electric scooter, it simultaneously and independently controls the two motors. On a high-performance remote-control car, a more extreme operating point is tested with one motor.

This book is all about running a brushless DC motor using a sensorless technique. The target of the work was to make a very simple operating method for a brushless motor and formulate a speed control mechanism. Initially the work was started with both considering back-EMF and without considering back-EMF. Because of more complexity in the back-EMF sensing method, and as our intention was to make a simpler and cost effective operation, so finally we assembled our project the without back-EMF sensing. Even though being a simple and inexpensive machine, the performance was quite good. However adding back-EMF sensing in this machine can give it more dependability.TABLE OF CONTENTS: DECLARATIONIAPPROVALIIACKNOWLEDGEMENTIIILIST OF FIGURESVIIABSTRACTIXCHAPTER 1INTRODUCTION101.1.Introduction101.2.Historical Background101.3.Advantage over Traditional Method111.4.Objective of this Work121.4.1.Primary objectives121.4.2.Secondary Objectives121.5.Introduction to this Thesis12CHAPTER 2BRUSHLESS DC MOTOR142.1.Introduction142.2.Comparison of Brushless motor with brushed motors152.3.Structure of a BLDC152.3.1.Stator162.3.2.Rotor172.4.Operating Principle182.4.1.Sensored Commutation192.4.2.Conventional Control Method Using Hall-effect Sensors202.4.3.Sensorless Control222.5.Applications232.6.Summary24CHAPTER 3MOTOR DRIVE SYSTEMS253.1.Introduction253.2.Components of Drive Electronics253.3.Inverter263.3.1.Three-Phase Inverter263.3.1.1.120-Degree Conduction273.3.1.2.180-Degree Conduction293.4.Speed Control Techniques303.4.1.Open Loop Speed Control313.4.2.Closed Loop Speed Control313.4.2.1.Proportional-Integral (PI) Controller323.5.PWM based Methods333.5.1.Conventional 120° PWM technique333.5.2.PWM Duty Cycle Calculation333.6.Summary34CHAPTER 4SIMULATION354.1.Introduction354.2.Simulation354.2.1.Simulating Three-Phase Inverter364.2.2.Simulating Controller Unit384.3.Simulation Results394.3.1.Speed Control404.4.Summary40CHAPTER 5HARDWARE IMPLEMENTATION415.1.Introduction415.2.Equipments and Components425.3.Power Supply Unit435.4.Microcontroller Unit445.5.Motor Drive Unit455.6.Performance of the System465.7.Summary47CHAPTER 6DISCUSSIONS AND CONCLUSIONS486.1.Discussions486.2.Suggestion for future Work496.2.1.Limitations496.2.2.Future Scope496.3.Conclusions50REFERENCES51APPENDIX A53SPEED CONTROL FLOWCHART53APPENDIX B54MICROCONTROLLER CODES54APPENDIX C55ATMEGA32 (MICROCONTROLLER)556.3.1.Pin Descriptions556.3.2.Block Diagram586.3.3.Electrical Characteristics59APPENDIX D60L298 (DUAL FULL-BRIDGE DRIVER)606.3.4.Pin Configurations606.3.5.Maximum Ratings61

Brushless electric motors are used in a number of underwater vehicles. When these underwater vehicles are used for mine clearance operations the magnetic signature of the brushless motors is important. The magnetic signature of two models of brushless motor designed by the Kollmorgen Motion Technologies Group for use in submersible systems were examined. Magnetic mapping around the motors was performed so the influence of the individual elements of the motors could be isolated. The major component of the magnetic field was determined to be due to the shaft and rotor section of motor.
