DISTRI TOOL 2H12

Brushed – Permanent Magnet

• Advantages

– Simple to drive

– Easy speed control

– Relative simple contruction

• Disadvantages

– Brushes wear

– Brushes arc and produce EMC

– Rotor has relative large enertia

– Commutator increases the length of the motor

– Coils are rotating inside the stator and are difficult to cool

What is a Stepper Motor ?

• 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.

• It converts digital pulses into mechanical shaft rotation.

• In other words: it is a digital motor

DISTRI TOOL 2H12

Stepper Motor Types

• 3 basic versions, different in construction based on the use

of permanent magnets and/or iron rotors with laminated

steel stators:

– Permanent magnet

– Variable reluctance

– Hybrid

DISTRI TOOL 2H12

Hybrid Type

DISTRI TOOL 2H12

Examples of Hybrid Type

DISTRI TOOL 2H12

How to make a stepper run

• We concentrate further on 2 phase stepper motors

• How many wires:

– 4 = unifilar

– 6 = bifilar

– 8 = “super”bifilar

DISTRI TOOL 2H12

Stepper Motor Windings

• Unifilar:

– Only one winding per stator pole

– Difficult to drive because coil current direction needs to be

reversed

– Stepper motors with a Unifilar winding will have 4 lead wires.

M

DISTRI TOOL 2H12

Stepper Motor Windings

• Bifilar

– two identical sets of windings on each stator pole

– Easy to drive because no need to change current direction in

the windings. This configuration simplifies operation in that

transferring current from one coil to another one,

– Stepper motors with a Bifilar winding will have 6 to 8 lead

wires

How to increase the resolution?

• Buy a high resolution motor:

– Variable reluctant

• Drive the motor in a clever way

– Introducing micro-step

How to control the current level

• By using Pulse Width Modulation (PWM)

• Switches in H-bridge are chopping the voltage across the coil:
