Wiring motors
« on: July 17, 2008, 03:13:05 PM »
Hello,

For wiring motors, it is written as the following:

AA AA#  AB AB#     ZA ZA#  ZB ZB# etc
is this mark # that means + ?

thanks a lot

Robhi,

What type of driver are you using? Also are the motors bipolar or unipolar? There is no real +/- with steppers, if they go the wrong way either switch one pair of leads or invert the direction in the software.

Hello,
thank you for answering , for the electronic  I use the following one :

The XS-3525/8S-4 Stepper Motor Driver Board (Ver 4.00) $185.00

The Perfect Choice For Your Sherline or Taig Four Axis CNC Retrofit

Four axis bipolar drive
±2.5 Amp/Phase PWM controlled drives
up to 35 Volt (w/BEMF)
FULL, HALF, QUARTER, & EIGHTH step/Full Step
Built-in DC-DC Converter for 5 Volt Logic
Filtered and Buffered STEP & DIR Signals
Built-in Break-out:Screw Terminals for Unused Parallel Port I/O
Synchronous Rectification
Internal UVLO and Thermal Shutdown circuitry
Easy connect for most popular Step/Direction control software
Small Size: 5.65" X 2.85"

and for the motors, I use the following ones :-

Code 160-010-00400
Type Hybrid Stepper
Holding Torque 220Ncm
Step Angle 1.8°
Rated Voltage 7.5V
Rated Current 2.5A/Phase
No. of Wires 8
Size 57x57x115mm
Shaft Dia. 10mm
Shaft Length (Front) 30mm
Shaft Length (Rear) 30mm
Net Weight 1.74kg

Motors will be wired in bipolar way ...

That all what I can say, I am a taxi driver , so I let you imagine the rest..

Thank in advance for your help

Robhi,

Do you have a link to the website with the motor wiring so I may advise on the wire combinations?

Hi, sorry to answer you so late , I was some place where had no connection..

the link for the motors  is   http://www.arceurotrade.co.uk/Catalogue/Stepper-Motors
and mines are :-
Code 160-010-00400
Type Hybrid Stepper
Holding Torque 220Ncm
Step Angle 1.8°
Rated Voltage 7.5V
Rated Current 2.5A/Phase
No. of Wires 8
Size 57x57x115mm
Shaft Dia. 10mm
Shaft Length (Front) 30mm
Shaft Length (Rear) 30mm
Net Weight 1.74kg
I would like to wire them in bipolar series with my drive :-

Four axis bipolar drive
±2.5 Amp/Phase PWM controlled drives
up to 35 Volt (w/BEMF)
FULL, HALF, QUARTER, & EIGHTH step/Full Step
Built-in DC-DC Converter for 5 Volt Logic
Filtered and Buffered STEP & DIR Signals
Built-in Break-out:Screw Terminals for Unused Parallel Port I/O
Synchronous Rectification
Internal UVLO and Thermal Shutdown circuitry
Easy connect for most popular Step/Direction control software
Small Size: 5.65" X 2.85"

I hope this will be the right answer

thanks a lot

Robhi,

The data sheet for that motor shows the connections for series bipolar on page two, For BIPOLAR SERIES:
Join YELLOW A to BLUE C and insulate connection
Join PURPLE B to BROWN D and insulate connection
Winding One then equals RED and BLACK
Winding Two then equals WHITE and GREEN

You should be OK with that setup.

Hi,
Thank you for your answer,

jouster one more thing please, on the drive it is written as this :

ZA ZA#  ZB ZB#

the place where I have to wire the motors. I don not how to wire them and which wire goes to this place or another...

thank you again for your answer.

Connect either red and black to ZA and ZA# and the white and green to ZB and ZB#, if the motors turn in the wrong direction just reverse one pair (red/black for example)

I use exactly the same motors.

The stepper motors have 8 wires - this means that they have 4 coils - two North/South and two East/West.

Your stepper motor driver boards only have four wires, so you must wire the coils together, the North/South together and the East/West tpgether.

You can do this by wiring them in series or in parrallel.
In series the motors will use less current - but not be as powerful. (Wire up as Kirsten says)
In parrallel they will be more powerful, but use more current. (see below)

These motors are rated at 2.5 amps at 7.5 volts - but that is for one coil. I use(d) 24 volts  to drive them, and wired them in series. The drives I used were rated at 2.5 amps. This got me going - but I later found that the motors would not give me enough speed.

I connected them in parrallel AC - A#C#  and BD - B#D#. The only trouble was that this method required about 4 amps to drive it and the drives were only 2.5amps. I changed to Gheko drives. The difference is fantastic - my speed before was about 4 ins per minute (steel cutting lathe), now I could get up to 40" per minute - a 10 times increase. I have settled in the high 20's for accuracy. I have now increased the drive voltage to 36 volts.

Just a quick word of warning - reading your post - the drives you have chosen seem to say they are PWM drive. Mach 3 does not use PWM control - it uses step and direction pulses to control the axis motors.
Before you buy them just check that they have a step/direction input to them - not a direction/PWM






Not me driving the engine - I'm better looking.
