pulse motor Explanation: In a pulse motor comprising a rotor, a drive coil excited by a predetermined drive current to drive the rotor, and a yoke for guiding a magnetic flux generated by the drive coil to a predetermined magnetic path; the yoke is provided with an aperture to restrict the flow path of an eddy current induced by the magnetic flux generated by the drive coil. |

pulse jet motor = athodyd Explanation: Either of the other answers could be right, but there is also the pulse jet motor or athodyd (aero-thermo-dynamic duct) as used by the Germans in the Second World War as the power unit for flying bombs. www.pulse-jets.com :: View topic - Experimental athodyd jet unit ... Ahhh, but the term, "ATHODYD", is a term the russian pulse jet enthusiasts liked to call their valved pulsejet creations, also. So, we'll just use it here ... www.pulse-jets.com/phpbb2/viewtopic.php?t=1484&view=previou... - 32k - Supplemental Result |

A stepper motor: 'a motor that can divide a full rotation into a large number of steps' Explanation: Had to research this so all I can do is send results; it's the first I've heard of the motor too. 1. (from the Janome site) What is the Stepping Motor? A stepping motor, also known as a **pulse motor**, is a motor whose rotation speed is determined by the number of input pulse signals... 2. (from the Wikipedia site) "A stepper motor is a brushless, synchronous electric motor that can divide a full rotation into a large number of steps, for example, 200 steps. Thus the motor can be turned to a precise angle." -------------------------------------------------- Note added at 3 hrs (2007-06-17 21:16:27 GMT) Post-grading -------------------------------------------------- Hmmm, Tony M. I know very little about this, but Googling "stepper motor" + "air conditioning" brings up almost 40,000 hits....
