Short Desciption:
[ Permanent magnet step motor ~ Variable Reluctance type Step Motor ~ Typical specification of a step motor ~ Driving Circuit ~ Static Torque Curve ~ Static Position Error ~ Dynamic Response ~ Continuous Operation ~ Control of Step Motors ]

Summary:
objectives: Explain how a step motor is different from a conventional motor; Identify the major constructional difference between a permanent magnet and variable reluctance type motor; Distinguish between the terms full stepping and half stepping; Develop the switching sequence for a given step motor according to given requirements; Calculate the step angle; Explain what is meant by static position error; Name two different modes of operation for continuous rotation; Explain with schematic diagrams, open loop and closed loop control schemes used for step motors; contents: [ Permanent magnet step motor ~ Variable Reluctance type Step Motor ~ Typical specification of a step motor ~ Driving Circuit ~ Static Torque Curve ~ Static Position Error ~ Dynamic Response ~ Continuous Operation ~ Control of Step Motors ]
