  • 5. 3.Bipolar Stepping Motor U? A BI-POLAR_STEP_MOTR L = 10m R = 8.4 • The electrical equivalent circuit of each phase consists /A of an inductance of the phase winding series with resistance. /B B • The inductance is ideal (without saturation characteristics and the mutual inductance between phases) • The motor back EMF is set as zero to simplified the model parameters extraction. Input the inductance and resistance values (parameter: L, R) of the stepping motor, that are usually provided by the manufacturer datasheet, to generally model the phase winding.

  • 7. 5.Signal Generator The signal generators are used as a microcontroller capable of generating step pulses and direction signals for the driver. There are 3 useful stepping sequences to control unipolar stepping motor One-Phase (Wave Drive) CLK FA CLK FA CLK FA • Consumes the least power. /FA /FA /FA • Assures the accuracy regardless of the winding imbalance. /FB /FB /FB FB FB FB Two-Phase (Hi-Torque) U? U? U? • Energizes 2 phases at the same time. 1-PHASE 2-PHASE HALF-STEP PPS = 100 PPS = 100 PPS = 100 • Offers an improved torque-speed result and greater holding torque. Input PPS (Pulse Per Second) as a clock pulse speed(frequency). Half-Step • Doubles the stepping resolution of the motor. • Reduces motor resonance which could cause a motor to stall at a resonant frequency. • Please note that this sequence is 8 steps.
