Typical Structure and Working Principle of Permanent Magnet Alternator

Typical Structure and Working Principle of Permanent Magnet Alternator - PMA A permanent magnet alternator (also called PMA, permanent magnet generator, PMG or magneto) relies on the magnetic field generated by a permanent magnet to convert mechanical energy into electrical power. It can generate AC current, with which it can power the whole [...]

How to get the neodymium magnets out of the hard drive

Hard Drive Magnets - Strong and Fun Hard drive magnets can be heaps of fun. I take them out of my old hard drives and distribute them to my brothers. They can be useful for holding things together and are fun to fiddle with. They can be used to fix the book that was open [...]

Drive Magnets

Want free rare earth magnets? Got a dead hard drive? You're in business. What, you might be wondering, are super-strong magnets doing inside a magnetic storage device? You're meant to keep magnets away from your drives, aren't you? Well, yes, you are. A sufficiently strong magnetic field across the storage surfaces can destroy data in [...]

Linear Motor Basics

A steady increase in practical industrial applications has secured a place for linear motors. Here's an overview of the various types of linear motors and what differentiates them from their rotary counterparts. For an in-depth analysis of the principles of linear motors established in this article, see Linear Motors Application Guide. The linear motor has [...]

Brush DC Motor Workings

Brush DC Motor Basics Brush DC technology originates from a design based on an ironless rotor (self-supporting coil) combined with a precious metal or carbon copper commutation system and a rare earth magnet, ferrite or Alnico magnet. It offers distinct advantages for high-performance drive and servo systems: low friction, low starting voltage, absence of iron [...]

What is a linear motor – Direct drive advantages

Why adopt linear motors? Direct coupling of the payload to the motor’s moving part eliminates the need for mechanical transmission elements such as leadscrews, timing belts, rack and pinion, and worm gear drives. Unlike brushed motors, there is no contact between the moving parts in a direct drive system. Therefore there is no mechanical wear [...]

What is a linear motor – Principle

Linear motors are a special class of synchronous brushless servo motors. They work like torque motors, but are opened up and rolled out flat. Through the electromagnetic interaction between a coil assembly (primary part) and a permanent magnet assembly (secondary part), the electrical energy is converted to linear mechanical energy with a high level of [...]
