stepper motor drive
1Stepper motor — A stepper motor (or step motor) is a brushless, synchronous electric motor that can divide a full rotation into a large number of steps. The motor s position can be controlled precisely, without any feedback mechanism (see open loop control).… …
2stepper motor — noun or stepping motor : a motor whose drive shaft rotates in small steps rather than continuously …
3Motor controller — A motor controller is a device or group of devices that serves to govern in some predetermined manner the performance of an electric motor.[1] A motor controller might include a manual or automatic means for starting and stopping the motor,… …
4motor — [1] An electrically driven power unit (electric motor). This term is often incorrectly (but commonly) applied to an internal combustion engine. [2] Rotating machine that transforms fluid or electric energy into a mechanical motion. [3] An engine… …

8Synchronous motor — A synchronous electric motor is an AC motor distinguished by a rotor spinning with coils passing magnets at the same rate as the alternating current and resulting magnetic field which drives it. Another way of saying this is that it has zero slip …
9Disk-drive performance characteristics — are the attributes which control the time it takes to transfer (read or write) data between a computer and a data storage device (most typically disk storage) starting with the initial command from the computer or host until the storage device… …
10Reluctance motor — A reluctance motor is a type of synchronous electric motor which induces non permanent magnetic poles on the ferromagnetic rotor. Torque is generated through the phenomenon of magnetic reluctance.:A reluctance motor, in its various incarnations,… …
