> CNC engraving machine spindle motor type of stepping motor and the connection mode of
the spindle motor should choose what kind of, is to let customers bamboozling, because the spindle motor can be said to be the core of the CNC engraving machine accessories, chosen correctly or not is related to after engraving effect.
So, today we are stepping motor in detail introduce the concrete types and connection mode.
the type of step motor and wiring
for amateurs, the easiest way to get the stepper motor is single polarity (
Also known as double or four phase)
And bipolar (
Also known as single or two phase)
Stepper motor.
single polar stepper motor
the stepper motor is referred to as the single polarity because each winding current to flow along one direction only.
It is also referred to as the two line stepper motor, because it only contains two coils.
The reverse polarity, two coil winding on the same core, with the same intermediate tap.
Single polar stepper motor also referred to as 4 phase stepper motor, because it has four excitation winding.
Single polarity of stepper motor fuses have 5 or 6.
if the leads of the stepper motor is 5 root, then one of them is connected to the public line f v +)
, the other four four phase respectively connected to the motor.
If the leads of the stepper motor is 6, so it is more sections of a unipolar stepper motor has two windings, each winding have asked tap in a lead.
But how to distinguish the lead?
Please continue to read the following content.
Distinguish line 5 single polar stepper motor connector
5 line unipolar stepper motor to find out every lead properly configured, needs to be done in advance a actually very simple.
Figure 1 shows the five line of stepper motor's basic lead configuration.
in order to find the right order and make the motor rotation, lead to a battery and a tape (
Of course also need a 5 wire stepper motor 1.
Lead is ready marker to indicate to tell them apart.
According to the following steps:
1, use digital multimeter find public line.
Ask other fuses with the public line of the resistance of the measured values are the same.
Connect this wire to the battery of v +.
5 v or 6 v is enough to test.
2, taped to the stepper motor output of uranium, and make it became a sign out perpendicular to the shaft end.
The function of this flag is to determine whether the motor rotation.
3, arbitrarily pick out a lead is called phase 1.
If this connection, the motor output shaft will do slight rotation.
Now step motor is locked in the position of phase 1.
4, get another wire and the ground, look carefully on the output shaft of the tape.
If the output shaft rotate slightly to the right, then the root lead is phase 2.
5, get another line and its grounding, careful observation on the output shaft of tape.
If the output shaft rotate slightly to the left, then the root lead is phase 4.
6, and then take another line and its grounding, careful observation on the output shaft tape motion state.
If you don't rotating output shaft, then the root lead is phase 3.
Distinguish line 6 single polar stepper motor connector
recycling old printer motor when the most commonly encountered this type of unipolar stepper motor.
Line 6 single polar stepper motor usually looks like two single sections of stacked together, each single section has three lines elicit f)
。
This is a very easy to distinguish the leads of the stepper motor.
6 line tell the stepper motor fuses order work is quite simple.
If it is the structure of many sections of stepper motor, then the order of the lead has actually been given, with the digital multimeter can identify each public line of winding.
Just keep winding for two fuses corresponding consistent, it doesn't matter whether they order only affects the direction of rotation of motor.
if not more sections of the 6 line stepper motor, the winding of the wire can be identified according to the following steps:
1, using a digital multimeter find public side each pair of windings.
2, according to the above methods can find two winding, separating them and marked.
Please send one winding of marked A and C (
Can also be a l and 3)
And the other a tag for B and D (
Can also be a 2 and 4)
。
In each pair of windings, which fuses what order is not important, as long as the pair is enough.
this is stepping motor types and connection mode in detail, customers can look at in detail, such for CNC engraving machine operation, the abnormal situations should be how to deal with the spindle motor has helped.
And to understand its characteristics, can help customers to better use.
of course, a lot of carving factory home will recommend using servo motor for the client, do better than the stepping motor servo motor performance, but it also increased the CNC engraving machine prices accordingly.
If the client is ordinary engraving and cutting, choose domestic stepper motor is enough to meet the processing needs.
