We are pleased to present our first annual Engineering Showcase, a celebration of some of the leading products and companies in mechanical power transmission. In the pages that follow, you’ll find examples of engineering excellence and technological know-how in the field of gears, drives, couplings, machine parts and other mechanical components.
Recently I had a disturbing conversation with a colleague here at the office. During the conversation, it became clear to me that my co-worker -- a really
intelligent guy whom I respect a lot -- had no idea how even the most simple electric motor works.
When designing a spur-crown pair, is there a formula, guideline or design guide for adapting the spur teeth for the radial angle of the teeth in the crown?
Everything started in 1800 when Volta developed the first DC battery. Faraday used the DC battery to develop the first electric motor. It used brushes to transfer the battery voltage and current to the rotating disk rotor. This was in mid-1831. Thus was born the brush DC motor.
The purpose of DC motor protection is
to extend a motor's lifespan by protecting
it from conditions that can damage the motor's windings--both electrically
and mechanically.
