## Stepper Motor Voltage Formula:

Stepper motor voltage is a critical parameter in the operation and control of stepper motors, which are used extensively in automation and precision positioning systems.

The voltage required to drive a stepper motor is determined by the motor’s internal phase resistance and the current flowing through its coils.

This voltage is essential for determining the power input necessary for the motor to achieve the desired mechanical output, influencing the torque and speed of the motor.

An accurate voltage calculation ensures the stepper motor operates efficiently without overheating and with minimal electrical noise.

Stepper motor voltage, Vsm(V) in volts is calculated by multiplying the current, Ism(A) in amperes by phase resistance, PR(Ω) in ohms.

Stepper motor voltage, Vsm(V) = Ism(A) * PR(Ω)

Vsm(V) = stepper motor voltage in volts, V.

Ism(A) = current in amperes, A.

PR(Ω) = phase resistance in ohms, Ω.

### Stepper Motor Voltage Calculation:

1. Calculate the voltage required for a stepper motor with a current of 2 amperes and a phase resistance of 1.5 ohms:

Given: Ism(A) = 2A, PR(Ω) = 1.5 Ω.

Stepper motor voltage, Vsm(V) = Ism(A) * PR(Ω)

Vsm(V) = 2 * 1.5

Vsm(V) = 3V.

1. Determine the phase resistance needed for a stepper motor with a current of 1.2 amperes and the voltage is 2.4V:

Given: Ism(A) = 1.2A, Vsm(V) = 2.4V.

Stepper motor voltage, Vsm(V) = Ism(A) * PR(Ω)

PR(Ω) = Vsm(V) / Ism(A)

PR(Ω) = 2.4 / 1.2

PR(Ω) = 2 Ω.
