Stepper motors are commonly used in many industrial and automation applications because of their accuracy and ability to perform precise movements. A common type of stepper motor used is the 6 wire stepper motor which offers a variety of wiring configurations. In this article, we will discuss the 6 wire stepper motor wiring diagram and how it works.
Overview of the 6 Wire Stepper Motor
The 6 wire stepper motor is a bipolar stepper motor which requires a bipolar stepper driver to operate. It has two coils with three wires in each coil. The wires are labeled A, B, and C for the first coil and D, E, and F for the second coil. The motor can be wired in a variety of ways to produce different movements.
Wiring Configurations
There are several wiring configurations available for the 6 wire stepper motor. These include:
| Configuration | Wiring |
|---|---|
| Series | A-C, D-F, B-E |
| Parallel | A-D, B-E, C-F |
| Half-Coil | A-D, C-E, B-F |
| Microstepping | Varies depending on the driver |
Series Wiring
In series wiring, the two coils are wired in series. This configuration produces high torque and low speed. The wiring is as follows:
A-C, D-F, B-E
To move the motor, the current is applied to the A-C and D-F coils alternately. This causes the rotor to step in 1.8-degree increments.
Parallel Wiring
In parallel wiring, the two coils are wired in parallel. This configuration produces high speed and low torque. The wiring is as follows:
A-D, B-E, C-F
To move the motor, the current is applied to the A-D, B-E, and C-F coils simultaneously. This causes the rotor to step in 0.9-degree increments.
Half-Coil Wiring
In half-coil wiring, only half of each coil is used. This configuration produces high torque and low speed. The wiring is as follows:
A-D, C-E, B-F
To move the motor, the current is applied to either the A-D or C-E coils and then to the B-F coil. This causes the rotor to step in 1.8-degree increments.
Microstepping
Microstepping is a technique used to produce smoother movements by dividing each full step into smaller steps. The wiring for microstepping varies depending on the driver being used.
