VSM0620 Permanent Magnet Stepper Motor 4 Bare Pins D Shaft 5V DC 18° Angle 14Ω/phase

Micro VSM0620 6mm diameter 4 bare pins D shaft 5V DC 18° angle stepper motor

Description:

This stepper motor (VSM0620) is 6mm diameter, and it has about 1.2 g*cm of pull-out torque.

Due to the small size, it has very limited torque.

This motor has D output shaft, and we can also make it round shaft if customers require it.

The motor comes with naked pins. (4 pins)

It does not have a FPC or PCB board.

We can design a FPC or PCB if customer want something more convenient to test/use.

It’s all up to customer’s choice.

About Micro stepper motor:

Our micro stepper motors generally have 18 degrees step angle.(Full step driving)
That means it takes 20 steps to rotate one turn.
Motor’s step angle is related to internal stator’s design.

We have micro stepper motors with different diameters, and motor’s torque is related to its size.
Here is relationship between motor’s diameter and torque(with suitable running frequency, at rated voltage):
6mm motor: about 1 g*cm
8mm motor: about 3g*cm
10mm motor: about 5 g*cm
15mm motor: about 15 g*cm
20mm motor: about 40 g*cm

Application of stepper motors:

Cameras - 6mm steppers are commonly found in SLR, DSLR and mirrorless cameras where they control the aperture diaphragm and shutter curtain. Their small size and precise performance fits well in the compact design of modern cameras.

Instruments - Mini steppers move parts and components in precision instruments like spectrometers, oscilloscopes and signal generators. Their accurate motion control enables high resolution measurements and analyses.

Flash Units - 6mm steppers power the flash units in cameras, allowing control over flash duration and intensity. Their small size contributes to the compact form factor of modern flashes.

Optics - Micro steppers position optical lenses, mirrors and prisms in devices like telescopes, microscopes, spectacles and binoculars. Their ability to move precisely in small increments enables optimal optical system adjustments.

Medical equipment - 6mm steppers are used in components of medical diagnostic devices like CT and MRI scanners. Their miniature size suits the design of delicate medical instruments.

Robotics - Micro steppers provide motion control for small robotic devices and components like miniature grippers. Their precise torque allows for manipulation of finer payloads.

In summary, 6mm micro stepper motors offer capabilities that are well matched to the requirements of applications that need very small, precise motion control. Their miniature design allows for integration into compact systems while still providing features like programmability, long life and low noise. As a result, they are well suited to a variety of applications across industries where tiny but precise motion is required.

Advantage of stepper motors:

Compact size - At only 6mm in diameter, micro steppers offer an extremely small footprint that enables easy integration into miniature and space constrained devices. Their tiny dimensions allow for compact system designs.

High precision - Despite their small size, micro steppers can provide precise motion control capabilities. With step angles down to 0.09 degrees, they can achieve positioning accuracies of around 5μm or better. This precision is well suited for miniature optical, medical and instrumentation applications.

Easy control - Micro steppers are digitally controlled using simple step and direction inputs, making them easy to integrate into electronic systems. Their digital input suits control by microcontrollers and other digital control circuits.

Long operational life - When operated within specifications, micro steppers can provide reliable service lives of many years. Their longevity stems from having no mechanical commutation and few wear parts.

Variable speed control - The speed of micro steppers can be precisely controlled from very low speeds up to several thousand steps per second. This variable speed capability suit a range of positioning and motion applications.

Low noise - Micro steppers have an inherently quiet operation due to the lack of contact switching and friction. Their silent performance is well suited for noise-sensitive applications.

In summary, 6mm micro steppers offer a compelling combination of tiny size with precision motion control capabilities. Their high resolution, ease of control, long life, quiet operation and adequate torque for their size class make them valuable actuation solutions for miniature systems requiring accurate motion. Their benefits are particularly suited for applications in optics, instrumentation, robotics and precision machinery.
