__Stepper Motor Torque Formula:__

The stepper motor torque formula is essential for determining the torque output of a stepper motor, which is a type of electric motor used in precision control applications. Stepper motors move in discrete steps, making them ideal for systems requiring precise movements and positioning.

The torque generated by a stepper motor, T_{sm(N.m)} in Newton metres, is calculated by multiplying the torque constant, KT_{(N.m/A)} in Newton metres per Ampere, by the current, i_{(A)} in Amperes, flowing through the motor.

Stepper motor, T_{sm(N.m)} = KT_{(N.m/A)} * i_{(A)}

T_{sm(N.m)} = Stepper motor in Newton metres, N.m.

KT_{(N.m/A)} = torque constant in Newton metres per Ampere, N.m/A.

i_{(A)} = current in Amperes, A.

1. A stepper motor with a torque constant of 0.5 N.m/A is used in a precision positioning system. If the motor operates with a current of 2.5A, calculate the torque it generates.

Given: KT_{(N.m/A)} = 0.5 N.m/A, i_{(A)} = 2.5A

Stepper motor, T_{sm(N.m)} = KT_{(N.m/A)} * i_{(A)}

T_{sm(N.m)} = 0.5 * 2.5

T_{sm(N.m)} = 1.25N.m.

2. To actuate a joint in a robotic arm, a stepper motor with a torque constant of 0.8 N.m/A is selected. If the required torque to move the joint is 2.4N.m, calculate the current needed through the motor.

Given: KT_{(N.m/A)} = 0.8N.m/A, T_{sm(N.m)} = 2.4N.m

Stepper motor, T_{sm(N.m)} = KT_{(N.m/A)} * i_{(A)}

i_{(A)} = T_{sm(N.m)} / KT_{(N.m/A)}

i_{(A)} = 2.4 / 0.8

i_{(A)} = 3A.
