Stepper Motor Maximum
Speed and Power Calculator See our other Electronics Calculators. Stepper motors are normally used for positioning, and are not known for their speed.� This calculator computes the maximum speed of a stepper motor, which is limited by the time it takes for the coil to energize to it's maximum holding current, and then de-engergize as polarity flips.� Equations: Current through the coil is proportional to the time that the voltage has been applied, and inversly proportional to the inductance.� I= V*T/L T= I*L/V For one step the current must go from 0 to Imax and back to 0, or alternatively from -Imax to +Imax.� I= 2*Imax T= L*Imax*2/V T is the number of seconds for a single step. To compute maximum revolutions per second - divide seconds per step by steps per revolution. Rev/sec = V/(L*2*Imax)/(steps/rev) Pmax= 2*Imax*V Pmax occurs not when the motor is going max speed because the current is a triangle wave.� Pmax occurs when the slope of the current is small compared to the on holding time of the step pulse. � Manufacturer LinksThe best way to find electronic parts is to use our free Electronics Component Directory, where a myriad of electronics manufactures are listed.
