Experimental Results of Variable Frequency Drive for Three Phase
... Abstract: Induction motor for many years has been regarded as the workhorse in industrial applications. An induction motor can run only at its rated speed when it is connected directly to the main supply. However many application need variable speed operations. With the invention of variable voltage ...

... damage to the brushes and commutator, or to the bearings, is possible at high speeds. Nominal voltage cannot be measured, but a typical no-load speed for a brushed DC motor is between 3000 and 10,000 rpm, so the nominal voltage will usually give a no-load speed in this range. For our data sheet, we’ ...

Drive and Motor Basics - Allen
... At running speed, the motor will operate between points F and D, depending on load. However temporary load surges may cause the motor to slip all the way back near point C on the “knee” of the curve. Beyond point C, the power factor decreases faster than current increases causing torque to drop off. ...

Stepper motor
A stepper motor or step motor or stepping motor is a brushless DC electric motor that divides a full rotation into a number of equal steps. The motor's position can then be commanded to move and hold at one of these steps without any feedback sensor (an open-loop controller), as long as the motor is carefully sized to the application in respect to torque and speed.Switched reluctance motors are very large stepping motors with a reduced pole count, and generally are closed-loop commutated.
