The least resolution ratio of the load is generally converted to the motor shaft, pay attention to the angle for each resolution ratio and the stepping angle of motor should be equal to or smaller than the angle.In general, the stepping angle of 2-phase motor is 0.9°/1.8°, that of 3-phase is 1.2° and that of 5-phase is 0.36°/0.72°.

filexlib. Permanent magnet (PM) stepper motor. Often referred to as a “tin can” or “can stack” motor, the permanent magnet stepper motor is a low cost and low resolution type motor with typical step angle of 7.5° to 15° (48 – 24 steps/revolution). PM motors as the name implies have permanent magnets added to the motor structure.

Stepper Motor Types There are three basic stepper motor types. They are : • Variable-reluctance • Permanent-magnet • Hybrid Variable-reluctance (VR) This type of stepper motor has been around for a long time. It is probably the easiest to understand from a structural point of view. Figure 1 shows a cross section of a typical V.R. stepper There are three stepping modes of a stepper motor. The stepping mode refers to the pattern of sequence in which stator coils are energized. 1. Wave drive (One phase ON at a time) 2. Full drive (Two phase ON at a time) 3. Half drive (One and two phase ON at a time) 1. Wave drive : In wave drive stepping mode only one phase is energized at a time.
This tutorial will not discuss in depth the driving of stepper motor. Most commercially available stepper motor drivers takes pulses as inputs. The amount of rotation of the stepping motor is proportional to the number of pulses given to the driver. The relationship of the stepping motor’s rotation and input pulses is expressed as follows.
Types of Electric Motors Following are the types of electric motors which are described below: DC Motor Shunt motor Separately excited motor Series motor Compound motor PDMC motor AC Motor Induction motor 1-phase induction motor 3-phase induction motor Synchronous motor Stepper motor Brushless motor Universal motor Hysteresis motor

Types of Stepper Motor There are three main types of stepper motors, they are: Permanent magnet stepper Hybrid synchronous stepper Variable reluctance stepper Permanent Magnet Stepper Motor Permanent magnet motors use a permanent magnet (PM) in the rotor and operate on the attraction or repulsion between the rotor PM and the stator electromagnets.

In Theory, a Stepper motor is a marvel in simplicity. It has no brushes, or contacts. Basically it’s a synchronous motor with the magnetic field electronically switched to rotate the armature magnet around. A Stepping Motor System consists of three basic elements, often combined with some type of user interface (Host Computer, PLC or Dumb
There are two general types of variable-reluctance stepper motors: single- and multistack. The chapter looks at the multistack device in some detail, followed by a brief discussion of the single-stack variable-reluctance stepper motor. Stepper motors are used to convert digital or discrete information into a change in angular position.
