There are two common systems of driving a stepper motor: constant current drive and constant voltage drive. The circuitry for the constant voltage drive is simpler, but it is relatively more difficult to achieve torque performance at high speeds. The constant current drive, on the other hand, is now the most commonly used drive method, …
Microstepping serves two purposes. First, it allows a stepping motor to stop and hold a position between the full or half-step positions, second, it largely eliminates the jerky character of low speed stepping motor operation and the noise at intermediate speeds, and third, it reduces problems with resonance. Although some microstepping controllers offer hundreds of …
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 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. …
This technical article describes the most accurate way to describe step error that is most meaningful to the step motor user. The traditional way to specify step accuracy is in the form of a percentage by taking the full step error divided by the fundamental step angle of the motor. Let’s understand this and see …
Linear stepper motor, or linear stepper motor, is rotated by the magnetic rotor iron core through the interaction with the pulsed electromagnetic field generated by the stator, and the linear stepper motor converts the rotary motion into linear motion inside the motor. The basic working principle of a linear stepper motor is to use a …
Stepper motors have a wide range of applications in many industries and disciplines, some of the more common uses are: Stepper motors for 3D printers A common 3D printer part list almost always includes some description of a stepper motor. This is because using a stepper motor in a 3D printer is a highly accurate …
It is important that the stepper motor develop enough torque with each step to drive the load. If it doesn’t, the motor will stall (not step). When steps are missed, the controller no longer knows the exact position of the load, which may render the system useless. At higher stepping rates, two problems occur. First, …
