leadshine stepper motor 57hs20-ec 1.8 degree 2 phase nema 23 with encoder 1000 line and 1.0 n.m torque

the response of the stepper motor is determined only by the digital input pulse, so open loop control can be used, which makes the structure of the motor simpler and controls the cost; only connecting the load directly to the shaft of the motor can also rotate at a very low speed; the speed is proportional to the pulse frequency and therefore has a wide range of speeds.
