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 ...
The invention relates to a process for controlling the revolution speed of a motor using an incremental detector so that the motor is to be simply controlled with lower starting torque and lower starting short-circuit current. To this end, the pulse width of a control signal taken to a final...
controller in controlling speed for a separately excited DC motor. Afterwards, we have analyzed both results to conclude that which technique is better to be adopted for precisely controlling the speed of DC motor. Outcomes from MATLAB fuzzy logic toolbox for simulation of our schematic has been ...

PURPOSE:To improve the responsiveness of controlling the speed of a motor by variably setting the time to become the reference of converting the rotating speed in response to the command value of the rotating speed or the rotating speed of a motor. CONSTITUTION:Rotating speed converting means PS...
PURPOSE:To enable a motor to assume a constant speed smoothly and rapidly, when a power source is turned on, by driving the motor by an output of phase comparison between a signal of frequency corresponding to revolution of the motor and a signal of the same frequency but a different phase...
PURPOSE:To reduce overspeed or deceleration and keep constant-speed character istic, by setting a means for returning generation current generated at a motor section at the time of overspeed or deceleration. CONSTITUTION:To a DC power source 1, the circuit of a power transistor 2 controlling pulse...
Thus, the speed of a DC motor can be controlled in three ways: By varying the supply voltage By varying the flux, and by varying the current through the field winding By varying the armature voltage, and by varying the armature resistance ...
