leadshine stepper 86cme45 86hbm40-ec-1000 86hs40-ec-1000 2 phase nema 34 with encoder 1000 line and 1.0 n.m torque

initially, the phase current control of the stepper motor is realized by hardware. usually, two methods are used, which use multiple power switch currents to supply current and superimpose current on the windings. this method makes the power tube loss less, but because of the road the number is large, so the device is large and bulky.
