Practical Results Figure 6-2 shows the motor torque output versus motor maximum speed for the two commutation algorithms developed in the reference design. Speed Vs Torque Speed (RPM) 4000 3500 3000 2500 2000 1500 1000 500 Tw o-MOSFETs Scheme Three-MOSFETs Scheme 0 0.93 2.54 4.34 6.08 7.82 9.43 11.76 15.28 18.20 21.49 24.65 27.93 Torque (lb-in) Figure 6-2. Speed versus Torque Motor Characteristic Current waveforms are shown in the two oscilograms: • Figure 6-3 for the commutation scheme switching two MOSFETs at a time • Figure 6-4 for the commutation scheme switching three MOSFETs at a time NOTE: There is less torque ripple, which is dependent on the current, for the commutation algorithm switching three MOSFETs.
