Stepper Motor Resolution
Compute the angular resolution of a stepper motor, R = 360°/(steps per revolution · microsteps), the smallest angle the shaft can position. A common 200-step motor (1.8°/step) with 16 microstepping reaches 0.1125° per microstep — 3200 positions per revolution. Microstepping smooths motion and raises resolution, though it lowers the holding torque per microstep. Enter the steps per revolution and the microstepping factor.

Resolução de motor de passo
Um motor de passo gira em incrementos discretos — não continuamente como um motor comum. A resolução nativa de um motor típico é de 200 passos por volta (1,8° por passo). O driver pode subdividir cada passo eletronicamente, o microstepping: R = 360°/(passos · micropassos). Com 16 micropassos, os 200 passos viram 3200 microposições por volta — resolução de 0,1125°. O microstepping suaviza o movimento (menos vibração e ruído) e aumenta a resolução aparente, mas com ressalvas: o torque por micropasso cai e a precisão absoluta de cada microposição não é perfeita. É a base do posicionamento em impressoras 3D, CNCs e robôs. Informe os passos por volta e o fator de micropassos.

Lead Screw Lead
Compute the lead of a ball screw or power screw, Lead = pitch · number of starts, the linear distance the nut travels per full turn of the screw. On a single-start screw the lead equals the pitch; with multiple starts the lead increases proportionally, allowing more linear speed at the same rotation. The basis of rotation-to-displacement conversion in CNC and linear actuators. Enter the pitch and the number of starts.
Motor Power (Torque × RPM)
Compute a motor's mechanical power from torque and rotation, P = τ·ω = τ·2π·n/60, where τ is the torque (N·m), n the rotation (rpm) and P the power (W). It is the fundamental relation linking the three quantities of a rotating motor: the same motor delivers high torque at low speed or high speed at low torque, but the power is the product of the two. The basis of drive sizing. Enter the torque and the rotation.
Stepper Motor Speed
Calculate the rotation speed of a stepper motor, RPM = (pps × 60 × step angle) ÷ 360, from the pulse frequency pps (steps per second) and the motor's step angle (degrees per step). The result, in revolutions per minute, relates the command frequency sent to the driver with the actual shaft speed. Stepper motors lose torque at high speeds, so there is a practical maximum rotation. It is essential for programming axis speeds in 3D printers, CNC and automation. Enter the pulse frequency and the step angle.
