the zd series of stepper motor controllers can be run using a range of external inputs, offers 25600 potential positions (on a standard 200 step stepper motor) and can be programmed to do virtually anything! however, as the above torque speed graph highlights, an increase in speed leads directly to a drop off in the torque available from the motor and controller.

the graph above shows a torque/speed curve of a typical d.c. motor. note that torque is inversely proportioal to the speed of the output shaft. in other words, there is a tradeoff between how much torque a motor delivers, and how fast the output shaft spins. motor characteristics are frequently given as two points on this graph: the stall torque,, represents the point on the graph at which the ...

if the torque and/or speed can reverse then some additional factors must be taken into account. for dc drives, a four-quadrant application requires two thyristor bridges to allow for the bidirectional dc current. the input current behaviour as the direction of rotation reverses is a continuation of the single-quadrant case, the power factor passing through zero at zero speed and then rising ...

because the torque-speed curve is a straight line, it's simple to find the torque that the motor can produce at a given speed, or conversely, to find the motor's speed for a given load (torque) on the shaft. recall the equation for a straight line: where: y = value of y axis variable, to be determined . m = slope of the line; change in y divided by change in x. x = value of x axis variable ...
