BIPOLAR STEPPER MOTORS (PART II): MICROSTEPPING AND DECAY MODES
In Part I of this series, we covered the bipolar stepper motor’s three control modes as well as its mechanical structure, including dual full-bridge drive. In Part II, we will discuss microstepping and how it controls the dual full-bridge drive. Previously, half-step stepping mode was introduced as a combination of single-phase stepping and full-step stepping to obtain more electrical angle pos...
BIPOLAR STEPPER MOTORS (PART I): CONTROL MODES
In the intelligent era, stepper motors are widely used due to their unique open-loop position control performance. Each device has specific requirements that ensure there is a smooth output torque while the stepper motor rotates. Rotation stability is closely related to the motor’s physical construction as well as its control mode. This article introduces the bipolar stepper motor and discusses i...
WEBINAR ON-DEMAND STEPPER MOTORS AND BACK EMF
In this webinar learn about Electro Motive Force (EMF), it's impact on motion in a stepper motor, how to measure it, and how that measurement can provide feedback about the motion system. Review Presentation
WHY MICROSTEPPING ISN'T AS GOOD AS YOU THINK
Stepper motors are often used for positioning since they are cost-effective, easy to drive, and can be used in open-loop systems — meaning that they do not require position feedback like servo motors. Steppers are used in small industrial machines, such as laser engravers, 3D printers, and office equipment like laser printers. There is a wide array of options when it comes to stepper motors. For ...
MP6500 & MP6600: INTEGRATED BIPOLAR STEPPER MOTOR DRIVERS
The MP6500 and MP6600 are bipolar stepper motor driver ICs. The MP6500 offers 2.5A peak output current and is available in in QFN-24 (5mmx5mm) and TSSOP-28EP packages. The MP6600 offers all of the same features and up to 1.5A of output current in a small QFN-24 (4mmx4mm) package. Beyond the standard integrated indexer logic and two PWM current-regulated H-bridge drivers, these parts provide unique...
STEPPER MOTORS BASICS: TYPES, USES, AND WORKING PRINCIPLES
In this article, we will cover the basics of stepper motors. You will learn about the working principles, construction, control methods, uses, and types of stepper motors, as well as its advantages and disadvantages. A stepper motor is an electric motor whose main feature is that its shaft rotates by performing steps, that is, by moving by a fixed amount of degrees. This feature is obtained tha...
