2 Phase Bipolar PM Miniature Linear Stepper Motor 25mm High Thrust With Gearbox

2-Phase Bipolar PM Miniature Linear Stepper Motor 25mm High Thrust With Gearbox For Automation Equipment

Description:

This SM25-412L motor has a 10:1 gear ratio gearbox inside, thus its pushing force is bigger compared to others (About 70N, 7KG of thrust)

This motor is very commonly used in TRV(thermostatic radiator valve ) and valve control.

The slower speed and high thrust is very suitable for valve control or similar applications.

About the design of this motor, there are two holes on motor’s cap (used as mounting holes), and hole distance is 37mm, and we also have 31 mm version.

This motor is attached with a 1.25mm pitch connector (Molex 51021-0400)

Application of stepper motors:

Medical devices: Linear stepping motors are widely used in medical equipment due to their precise movements, repeatability and controllability. They are commonly found in medical imaging devices, surgery equipment, robotic rehabilitation devices and wheelchair lifts. Their speed, accuracy and reliability make them ideal for the demanding requirements of medical applications.

3D printers: Stepper motors power the motion systems of many 3D printers, enabling precise layer-by-layer material deposition. Their high resolution, repeatability and ability to hold position during printing make them well suited for this use. They move the print bed, extruder head and filament feeders to produce accurate 3D objects.

Industrial precision control: Linear steppers provide precise, indexed movements ideal for positioning components in industrial automation systems. They can move loads with micron-level resolution over long travel ranges. They are used for pick and place machines, motion guides, slides, conveyors and assembly lines.

Automation: Linear steppers enable precise control of automation equipment like lab automation robots, packaging machines, pickers, sorters and palletizers. Their digital input makes them easy to control using a PLC or microcontroller. They provide flexibility, repeatability and high speeds for production automation tasks.

Motion mechanisms: Linear stepping motors offer rotational-to-linear and linear-to-rotary motion conversion capabilities. They can be integrated into robot arms, CNC machines, precision instruments, optical systems and test equipment. Their step-and-hold function allows holding position accurately without power.

In summary, 25mm linear stepper motors offer numerous benefits for applications requiring precision positioning, repeatability, speed and controllability. Their versatility in providing both linear and rotary motions enable their use in a wide range of industries including medical, automation, precision instrumentation, 3D printing and more. Their high performance and reliability make them well suited to meet the demanding motion requirements of modern technologies.

Advantage of stepper motors:

Precise control and programmability - Stepper motors have the ability to move and hold in precise increments in response to control signals. This allows for highly accurate and repeatable positioning. Step and direction inputs make them easy to programme and control.

No electromagnetic interference or sparks - As there are no brushes or commutators, steppers generate no electromagnetic interference or sparks which can cause issues in sensitive environments. This makes them suitable for use near electronic equipment.

Compact size - Linear steppers come in a variety of small sizes including 25mm. Their compact dimensions allow for easy integration into space constrained applications.

Reasonable price - Compared to servo motors, linear steppers offer a cost-effective solution due to their simpler design and lower part counts. Their prices scale well with size.

Low noise - Linear steppers generate very little acoustic noise during operation due to the lack of brushes and contact switching. This makes them suitable for applications where noise is a concern.

Long operational life - When sized properly and operated within their specifications, linear steppers can provide many years of reliable service life. Their long life is due to the absence of mechanical commutation and sliding contacts.

In summary, 25mm linear stepping motors offer a unique combination of precise positioning, low cost, compact size, ease of use, low noise and long life. These attributes make them well suited for applications ranging from medical devices to industrial motion control and automation. Their advantages over alternative motor types stem primarily from their simpler design, digital control inputs and lack of brushes and commutation.
