Product BrochureProduct Details:

A stepper motor is an electro mechanical device that converts electrical pulses into discrete mechanical motion as opposed to conventional motors with free running shafts. Many types of stepping motors exist with the permanent magnet (Hybrid) being the most popular. A variety of step angles are available, the widely used is the 1.80 per step or also referred to as the 200 step per revolution motor. The stepping action is achieved by switching the power to the motor windings, so that the motor phases are energized in a specific sequence. The motors have high holding torque when not being stepped, because of the current maintained in the motor winding.

HOLDING TORQUE:

 It is the maximum torque required to change the motor shaft step angle, when the stator windings are excited at the rated voltage.
ADVANTAGES:
Bi-directional operation.
Brushless design for reliability, simplicity.
Can be stalled repeatedly and indefinitely without damage.
Drift free.
High torque per package size.
Holding torque at standstill.
Inherently a digital device, number of pulses determine distance, frequency sets   the speed.
No extra feedback components required (encoders can be added for additional advantages).
Rapid response to starting, stopping and reversing.
Stable at zero speed.
Step angle error is very small and non-cumulative.

APPLICATIONS:

The broad capabilities of Stepper Motors have made them the electrical actuator choice in many fields of automation. Applications range from machines and equipment requiring very delicate motion control to a broad spectrum of automation categories including pick and place machines, cut to length machines, valve control, and machine-tool applications for metal cutting and transfer lines for automobile factories.
