Hybrid stepper motors (HSMs) are widely used in control systems because of their high positioning accuracy, compact size, and lower operation noise. Among various HSMs, the 3P-HSM has more advantages, such as higher torque and fewer MOSFETs in the control system, and thus, will dominate the HSMs market with the increase in market requirements in …

The Computer Numerical Control (CNC) is a technology that uses microcomputers to generate, parse and execute the sequential control that describes the end effector’s behavior. The application of this technique is often used in turning, drilling, milling or extruding machines. Recently its application has expanded to other tasks, such as: electronic components insertion, tube welding, …
Stepper motors belong to the synchronous motors group. Compared to other motors, when powered, stepper motors try to keep the shaft position in a defined balanced condition. Basically, the movement is achieved from the rotation, by a magnetic field generated into the stator and by the relative rotor chase. Figure 1 shows two excitation phases …
The key question to be answered by the high-level control system for a stepper motor is, when should the next step be taken? While this almost always depends on the application, the similarities between different applications are sufficient to justify the development of fairly complex general purpose stepper motor controllers. Stepper motor control may be …
The control method of stepper motor is generally divided into two control methods: open-loop control and closed-loop control. Among them, the simplest control method for open-loop control of stepper motor is the ring control system. Under this control method, the stepper motor controls pulses. The input of the motor does not depend on the position …
When you’re looking for a stepper motor, you’ll often see statistics related to torque. Torque information isn’t the only thing you’ll be looking at when it comes to selecting your motor, but it is important. Generally, you’ll be looking at information regarding how much torque the stepper produces under certain conditions. Before you start examining …
There are several factors to take into consideration when choosing a stepper motor for an application. Some of these factors are what type of stepper motor to use, the torque requirements of the system, the complexity of the controller, as well as the physical characteristics of the motor. The following contents focus on these considerations. …
A stepper motor is an electromechanical system which is transducing an electrical signal into a mechanical one. It is designed to accomplish a discrete movement (notion of step) and reach a precise position. The movement is achieved through the use of a magnetic field provided by coils and sensed by magnets. Indeed, when one of …
Stepper motors are mostly driven in open loop mode. Timing of the step pulses is defined by the controller, the motor is supposed to follow without loosing synchronism. Stepper motors are in fact natural positioning devices which do not require position feedback. The drawback of their design are important iron losses when running at high …
The following environmental and safety considerations must be observed during all phases of operation, service and repair of a stepper motor system. Failure to comply with these precautions violates safety standards of design, manufacture and intended use of the stepper motor, driver and controller. Please note that even a well‐built stepper motor products operated and …
