Stepper motor torque and speed characteristics explained

A stepper motor's holding torque is higher than its running torque and is limited primarily by the amount of current the motor can withstand. Stepper motors are able to hold a load in place, even against an external force, when the motor is stationary. Image credit: Oriental Motor U.S.A. Corp Detent torque

Stepper Motor Torque: What is the torque of a stepper motor?

The motor's torque rating is adequate for this application. If the load requires 2 Nm of torque, you would need a motor with a higher torque rating or consider reducing the load or using mechanical gearing to adjust the torque requirements. Conclusion. The torque of a stepper motor is a critical factor that determines its ability to handle ...

Speed - Torque Curves for Stepper Motors - Oriental Motor U.S.A. Corp.

Since the pull-in torque curve for a stepper motor varies depends on the inertial load attached to the motor, the pull-in torque curves are not shown in the speed - torque curves shown in catalogs. In order to operate above the pull-in torque curve, the motor must be accelerated into or decelerated out of the slew range. 12.

Stepper motor torque basics - Control Engineering

Holding torque is a measurement of how much rotating force is required to force a stationary stepper motor shaft out of position. Holding torque (T) is the product of a motor's torque constant (KT) and the current (i) applied to the stator windings. T = KTi . In most applications, electronic drivers control stepper motors.

PDF Primer - Stepper Motor Nomenclature, Definition, Performance and ...

the stepper motor moves to each stable step point, there is overshoot of position. Also note that as the motor crosses each step point, the angular velocity, and therefore the kinetic energy, is at a maximum. Even when stepper motors are driven at low pulse rates, the instantaneous angular velocity can be extremely high at these crossover points.
