4.3 Constant Voltage Drive
When the winding of the stepper motor is used for heavy conductors, the coil resistance Rw is very small, as shown in Figure 4.4. In each phase coil, the external resistance R is connected in series, so that the current limited by the winding is smaller than the rated current I. ... Read More

4. Drive and Control of the Stepper Motor
Stepper motor driver is a kind of actuator which transforms electric pulse into angular displacement. While stepper driver accepts a pulse signal, then it drives the stepper motor to rotate a fixed angle in the set direction. Its rotation is carried out step by step at a fixed angle. We can control the angular displacement by control the number of the pulses, at the same time ,we can control the v... Read More

3.3 Four Kinds of Motors
Because the HB type stepper motor has many gears on the rotor, the excitation flux will contain higher harmonics. The stator of the RM stepper motor is the same as HB stepper motor, the number of the poles of the cylinder permanent rotor is the same as the number of the HB style stepper motor rotor. ...

3.2 The Classification and Structure of the Rotor
The PM（Permanent Magnet） rotor is an internal rotor type (external stator, with an air gap in the middle), and the cylindrical rotor's outer surface is distributed with N and S poles (external surface without gears).... Read More
