A Brushless Servomotor has been developed by using interdisciplinary mechatronics engineering. A mechanical switching device (commutator) is replaced by electronic circuits and controllers resulting in maintenance free and high performance servo drive. The brushless servomotor is an ac motor, in all respects and is in fact called the ac servomotor. Combined with a dedicated control device, the performance of the brushless servomotor is found to be equal to the performance of the high performance dc servo motor. In dc motor when the current fl ....etc

Pulse Width Modulation is widely used in power electronics as a controller in power conversion and motion control. Among different types of modulating modes the Sinusoidal Pulse Width Modulation (SPWM) and Space Vector PWM are two common strategies in adjustable speed drive system. The Pulse width of SPWM varies with the Sine wave so as to restrain the lower order harmonics with easy control and large D C utilization. With successively improving reliability and performance of digital controllers, the digital control techniques have predominated ....etc

ceramic fasteners ppt

Stock Ceramic Fasteners

Stock ceramic fasteners from Ceramco are the solution for applications in which metal alloy or plastic fasteners fail, or simply do not possess the properties demanded by the environment in which they must exist. The following are just a few of the properties and characteristics of Ceramco s stock ceramic machine screws, nuts, bolts and washers:

High Temperature Stability Up to 2,000 C
Corrosion Protection Impervious to chemical attack, oxidation and UV light degradation
Wear Resistant Stand ....etc

Until now brake discs have been made up of grey cast iron, but these are heavy which reduces acceleration, uses more fuel and has a high gyroscopic effect.

Ceramic disc brake weigh less than carbon/carbon discs but have the same frictional values with more initial bite and cost a fraction of price. Carbon /carbon discs are used only in Formula 1 racing cars etc, because it is so expensive. More over ceramic brake discs are good even in wet conditions which carbon / carbon disc notoriously fails to do.

But comparing their weight, you will ....etc

Introduction to Servomotor Programming

Welcome to Servo Programming
In the previous chapters, we ve done some cool things, but we ve essentially treated our robot as a desktop
computer. Now we are ready to attach the BX-24 to a robot body and make it mobile with the use of
servomotors. In this chapter, you will learn what servos are, how they operate, and how modified servos can be
used as drive motors for the Robodyssey Mouse.
This chapter covers many important topics, so read it slowly and thoroug ....etc

ceramic cutting tool materials ppt

In the context of machining, a cutting tool or cutter is any tool that is used to remove material from the workpiece by means of shear deformation. Cutting may be accomplished by single-point or multipoint tools. Single-point tools are used in turning, shaping, planing and similar operations, and remove material by means of one cutting edge. Milling and drilling tools are often multipoint tools. Grinding tools are also multipoint tools. Each grain of abrasive functions as a microscopic single-point cutting ed ....etc
