d to the +ve
Our example is a 30o motor
The rotor has 6 poles and the stator has 4 poles
Example
Unipolar Motors
Torque vs. Speed
Motor Control Circuits
Fundamentally a circuit as below is required
Motor Control Circuits
We must deal with the inductive kick when the switches are turned off. We can shunt this using diodes.
Hybrid Stepper Moter
It is a combination of both permanent magnet and the variable reluctance.
It has magnetic teethed rotor which better guides magnetic flux to preferred location in the air gap.
The magnetic rotor has two cups:-
a.) North pol..................[:=> Show Contents <=:]

In case of a variable reluctance stepper:-
rotor moves to have a minimum gap with the stator
Stepper Motor Types
Variable Reluctance
Unipolar/Bipolar Permanent Magnet
Hybrid Step Motor
Variable Reluctance Motors
This is usually a four wire motor – the common wire goes to the +ve supply and the windings are stepped through
Our example is a 30o motor
The rotor has 4 poles and the stator has 6 poles
Example

Unipolar Motors
This is usually a 5 or 6 wire motor – with a centre tap on each of the two windings – the tw..................[:=> Show Contents <=:]
