A.P. Motronix pvt. Ltd offers stepper motor, which converts electrical pulses into discrete mechanical motion. This motor comes with following salient features:
Digital device, number of pulses determine distance, frequency sets the speed.
Drift free.
Step angle error is very small and non-cumulative.
Rapid response to starting, stopping, and reversing.
Brushless design for reliability, simplicity
High torque per package size.
Stable at zero speed.
Holding torque at standstill.
Can be stalled repeatedly and indefinitely without damage.
No extra feedback components required
Bidirectional operation.
