Product information "DFRobot bipolar stepper motor with planetary gearbox, 5.18:1, 1.8° step angle, 18kgcm, 3.4V"

DFRobot Bipolar Stepper Motor with Planetary Gearhead (18kg.cm)
This bipolar stepper motor with planetary gearhead (transmission ratio: 5.18) uses a standard 8mm D output shaft and has a step angle of 1.8° (200 steps/revolution). Each phase draws 1.0 A at 3.4 V, allowing a holding torque of 18kg.cm (176N.cm) (200rpm). The motor has a housing size of 42mm square and 40mm long, while the planetary gearhead has a diameter of 36mm and a length of 27mm. The motor has four colour-coded wires with open ends: Black and green connect to one coil; red and blue connect to the other. It can be easily mounted with 4 M3 threaded holes and controlled with the Dual Bipolar Stepper Motor Shield for Arduino (DRV8825).

The DFRobot Bipolar Stepper Motor with Planetary Gearhead is a high-precision and high-performance motor that is ideal for demanding applications in fields such as robotics, CNC machines, 3D printing and linear actuators. By combining a stepper motor with a planetary gearhead, this motor offers both precision and high torque, making it ideal for complex motion control applications.

Special features of the motor

Bipolar operation: The motor is a bipolar stepper motor, which means that each of the two coils (phases) can be polarised to change the direction of the magnetic field. In contrast to unipolar stepper motors, the bipolar motor utilises the entire coil, resulting in higher torque and better efficiency. However, it requires special drivers, such as the DRV8825, to precisely control the phases.
Planetary gearbox: The integrated planetary gearbox with a transmission ratio of 5.18:1 increases the holding torque to an impressive 18kg.cm (176N.cm). The planetary gear also ensures even power transmission, reduced vibrations and a longer service life.
Precise step angle: With a step angle of 1.8° (200 steps/revolution), the motor enables extremely precise motion control, which is essential in applications such as 3D printing or CNC milling.
High compatibility: The motor is easy to integrate into existing projects thanks to its standard 8mm D output shaft and four colour-coded connections. It is particularly suitable for applications that require high torques and precise control.

Advantages of the bipolar design

Higher torque: Bipolar motors utilise the entire copper wire in the coil, resulting in higher efficiency and greater torque.
Compact design: Compared to unipolar motors, bipolar motors are more compact as they require fewer windings.
Flexibility: They can be combined with various control systems such as the DRV8825 Dual Bipolar Stepper Motor Shield.
