1. 1. Sensorless Hybrid Field-Oriented Control Two-Phase Stepper Motor Driver

   Master-uppsats, Linköpings universitet/Reglerteknik

   Författare :Emil Lydell; [2023]
   Nyckelord :Stepper motor; Field-Oriented Control; FOC; Driver; Two-Phase; 2-Phase;

   Sammanfattning : Hybrid stepper motors are small electrical motors with high torque production, compared with other electrical motors of the same size. Hybrid stepper motors are reliable in open-loop systems, in Sinusoidal mode, but with a drawback of high power consumption. LÄS MER

3. 2. Construction and Control of a 3-axisAutomated Liquid Sampling UnitUtilizing Hybrid Stepper Motors

   Master-uppsats, KTH/Mekatronik och inbyggda styrsystem

   Sammanfattning : High accuracy autonomous positioning systems are becoming increasingly important in today’s chemical industry because they can obtain precise experiment results automatically and hence allow lab technicians to focus on other tasks concurrently. One time consuming process is the process of sampling chemical test results into the correct container, especially when the tests are many and infrequent. LÄS MER

5. 4. High Precision and Low-cost Stepper Motor Control for Industrial Implementation

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Chuyao Zhou; [2018]
   Nyckelord :;

   Sammanfattning : The industry is calling for a low-cost drive solution. The hybrid stepper motor isconsidered as a good candidate since it has much larger production than traditionalservo motor. In this thesis, the author comes up with a control solution of a hybridstepper motor based on a low-cost sensor, which reaches a high control resolutionwith a low cost. LÄS MER

7. 5. Multisensor fusion and control strategies for low cost hybrid stepper motor solutions

   Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Signaler och system

   Författare :Mattias Wallin; [2017]
   Nyckelord :Multisensor fusion; Hybrid Stepper Motor; Extended Kalman Filter;

   Sammanfattning : This thesis has explored if it is feasible to produce a good estimation of the rotational position of a stepper motor by using sensor fusion schemes to merge a sensorless position estimation (based on the back electromotive force) with the measurement from a magnetic rotational position sensor. The purpose was to find a cheaper alternative for position feedback in closed loop control from conventionally used rotational encoders and resolvers. LÄS MER
