Motor holding torque

Detent torque is produced when the windings are not energized. Holding torque is produced when the windings are energized but the motor is not moving. Stepper Motor Torque Speed Curve.

Holding Torque : amount of torque that the motor produces when it has rated current flowing through the windings but the motor is at . These features give them excellent acceleration and response, which in turn makes these motors well -suited for torque -demanding applications where the motor must start and stop frequently.

To meet the need for greater torque at low spee .

Which one matters to me (as Herb Tarlek might say)?

At higher speeds, the stepper motor is not as choppy, but it does not have as much torque. For information about how stepper motors work, see the . This phenomenon is generally recognized as torque. This torque of withstanding the external force is called the holding torque.

Holding Torque : This is the torque that the motor will produce when the motor is at rest and rated current is applied to the windings.

Any torque or speed required that exceeds (goes above ) . There are currently three general types of stepper motors. ORIENTAL MOTOR only manufactures Hybrid stepper motors. Variable reluctance step motors have teeth on the rotor and stator, but no magnet.

Therefore it has no detent torque.

There is no enough holding torque for the worm gear motor. Soft iron reluctance cores do not exhibit this behavior. Here is my generalized answer: The holding torque you need will be dependent on the load you are trying to m. That way, power is not required for the brake to hold. This type of motor is arranged such that the magnetic forces that create the motor rotation also cause the armature to move laterally such that when the motor is . This is accomplished by keeping the winding current high even though the rotor is aligned with the stator.

The following information is intended as an aide to understanding the terms used when discussing stepping motor applications.

Nominal holding torques range from 0. Fill in any unit to get all conversion. This is because motor torque is the vector sum of the phase currents. Advantage: Goes to full-steppers.

This is the maximum torque that the motor can provide with both windings energised at full current before it starts jumping steps. The torque is proportional to current (except at very low currents), .
