Live ChatUsing these two numbers and Excel, a torque speed curve for the 118743 motor running at 12 V can be generated. If there is no motor data sheet, then the torque speed curve must be determined through experiments. The no load speed can be measured for a slow moving shaft by attaching a tape flag to the shaft and using a stop watch to measure the

Live ChatThe speed torque curve extends to the second quadrant (Fig. 1.47). The speed of the motor decreases. The braking torque makes the motor run at constant speed, arresting its tendency to rotate faster. Due to the effects of stator resistance, the maximum torque developed during regeneration is greater than the maximum torque during motoring.
