STEPPER MOTORS CONTROLLER
Due to this, there has been widespread demand of stepper motors. The stepper motor can also be known as stepping A stepper motor requires an electronic controller to energies its windings in the proper sequence, thereby causing it to step. We designed this stepper motor controller and than … View Document

Two Wire Stepper Motor Positioner
You should expect your stepper motors to run very warm or even hot because power is applied to two windings at all times. You may have seen specifications or applications that use a resistor in series with the center tap of each winding. … Return Document
