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 …

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 …
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 …
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, …
