A speed control for controlling the speed of a DC motor provides improved speed regulation during transient loading conditions. The control includes a regulating circuit having an output for controlling the armature voltage to the motor, An input speed reference signal corresponding to the desired ...
For special applications, for example for drives of surgical, dental and dental-technician drilling, grinding and milling tools, stabilised-speed and vibration-free motors are required for very different speeds and loads. The e.m.f. sampling method which can be used without access into the motor...
motor includes a permanent magnet rotor and at least two stator windings successively energized by a switching circuit controlled by a voltage produced in dependence on both the rotor field and the value of a current which varies with rotor speed. In the motor shown the two stator windings L ...

The present invention relates to an apparatus and method for controlling the speed of a wound-rotor induction motor. Specifically, a wound-rotor induction motor according to one embodiment of the present invention comprises: a rectifying unit receiving AC power from rotor windings of the wound-...
Speed control unitsThe variation in speed of DC motors is obtained by varying either the armature voltage or the field voltage. The output signal generated by the pulse generator or tacho-generators is compared with the input value of the voltage to be applied to the DC motor, which ...
A driving circuit for a motor such as a spindle motor used in a floppy disc driver, a hard disc driver, etc. includes an output stage driver which supplies a driving current to a motor to rotate at a constant rotation speed. The driving current is supplied to the motor in an off- and...
The current study analyzed real-time speed control of a DC motor under various loads by using a Fuzzy Logic Controller (FLC). NI USB- 6218 DAQ was preferred as the data card for the system measuring the speed of the motor by a tachometer. Fuzzy logic control was employed by means of MA...
