1.5 degrees / 3 degrees


stepper motor applications (a) the choice of stepper motor step angle
stepper motor with (related to the phase number), static
torque,'digitizing' (http://www.eagledigitizing.com/), and current three
elements. Once the three factors to determine the step motor type will
be determined. 1, step angle selection of the motor step angle depends
on the accuracy requirements of the load, the load of the minimum
resolution (equivalent) conversion to the motor shaft,'cheap embroidery
digitizing' (http://www.eagledigitizing.com/), should take the number of
each point of the motor equivalent (including deceleration). Motor step
angle should be equal to or smaller than this angle. Stepper motor on
the market today are generally step angle of 0.36 ° / 0.72 °
(five-phase motor), 0.9 degrees / 1.8 degrees (two, four-phase
motor),'digitized embroidery designs' (http://www.eagledigitizing.com/),
1.5 degrees / 3 degrees (three-phase motor) and so on. 2, the choice of
static torque stepper motor is difficult to determine the dynamic torque
of a sudden, we tend to first determine the static torque of the motor.
Static torque motor on the basis that the work load, and load inertia
loads and friction can be divided into two kinds of loads. Single
inertial load and a single load of friction does not exist. Direct
starting time (generally low) when the two loads are to be considered,
the main consideration when accelerating inertia loads
starting,'embroidery digitizers' (http://www.eagledigitizing.com/),
constant speed into consideration as long as the friction load.
