STEPPER MOTORS
|
A stepper
motor is a
brush-less DC motor
whose rotor rotates
in discrete angular
step in response to each
input current pulse
receive by its
controller.
Step angle:
The angle
through which the motor shaft
rotates for each
command pulse is called
step angle.
Slewing rate:
|
The maximum
rate at which
the motor can step
unidirectionally is called
‘slewing rate’.
