DC voltage motor control also provides a limited range of speed control—and limited efficiency--because of the need for a specific start-up voltage that causes the … top watauga texas car insurance

"NettetAssuming the same steady-state performance observed in the more heavily filtered data, we can estimate the time constant based on the time it takes the motor speed to reach RPM. Since this appears to occur at 1.06 seconds and the input appears to step at 1.02 seconds, we can estimate the motor's time constant to be approximately 0.04 seconds. " - Motor speed constant
