Types of Linear Screw Stepper Motor

· Ball Screw Stepper Motor

A ball screw stepper motor is a type of linear actuator that converts the rotational motion of a stepper motor into linear motion by using a ball screw mechanism. The ball screw, which relies on recirculating ball bearings to reduce friction, is paired with a stepper motor to achieve precise and repeatable linear movement.

· Trapezoidal Screw Stepper Motor

A trapezoidal screw stepper motor is a linear stepper motor that utilizes a trapezoidal lead screw to convert the rotational motion of the stepper motor into linear motion. It's essentially a stepper motor coupled with a lead screw that has a trapezoidal thread shape. This configuration is commonly used in applications requiring precise and controlled linear movement, such as 3D printing.

Features of Linear Screw Stepper Motor

Improved machine speed and accuracy

High speed and High accuracy is possible by direct drive. Submicron high-precision positioning is possible depending on the resolution of the linear encoder.

Simplification of equipment structure

Mechanical linear motion conversion mechanisms such as ball screws or timing belts are not required. High degree of freedom in stroke length is available by extending the magnet rail.

Quiet and clean equipment

Quieter than the rotary motor system as noise-generating sliding parts such as ball screw for linear motion conversion mechanism is not used. Cleaner as no dust is generated from sliding parts.

Multiple uses of linear slides is possible

Since multiple coils (movers) can be placed on the magnet rail, it is easier to configure a multi-slide system.

Equipment maintenance can be reduced

The only sliding parts are linear guides. Simplification of maintenance is possible.

Installation Requirements of Linear Screw Stepper Motor

When the motor is connected to the driver, please do not connect the wrong phase.

Due to different driving conditions, the motor may have obvious heat. The surface temperature of the motor must not exceed 85°C during operation.

When installing the motor, be sure to use the front end cover of the motor to install the spigot for positioning, and pay attention to the tolerance fit to ensure the concentricity of the motor shaft and the load.

Applications of Linear Screw Stepper Motor

Pipetting - MLA + MLS

Tiny, precise, repeatable vertical motion is essential for accurate pipetting. Choose MLA to simplify your z-axis and MLS for precise, horizontal motion in pipetting applications.

Plate Vertical Positioning - MLA

Actuator assemblies are self contained and ideal for simplified, leveling applications where small radial or moment loads may be present.

Fluid Pumps - MLS + MLN

Regardless of the mounting configuration, a stepper motor linear actuator can increase pump pressure, reduce equipment footprint and more accurately disperse fluid.

XY Stages - MLS

Stepper motor linear actuators optimize XY stage designs with their compactness and power.

Horizontal Positioning - MLN

Cameras and other measurement devices need to be in just the right place at just the right time. MLN delivers reliable horizontal positioning and length selections to get your horizontal positioning job done right.

3D Printing - MLS

Utilizing a stepper motor linear actuator on a 3D printer can eliminate the need for couplings, bearings and supports while increasing stroke length and print volume.

Robotic Gripper - MLN

MLN configurations excel in gripping applications, rotating and positioning gripper heads and attachments with ease.

Monitor Tilting - MLA

Actuator assemblies are self contained and ideal for simplified, leveling applications where small radial or moment loads may be present.

FAQ

Q: How does a linear screw stepper motor work?

A: The motor rotates a screw (lead screw or ball screw), which translates the rotational motion into linear motion via a nut (either integrated or external). The stepper motor's rotor moves in discrete steps, and the screw-nut system converts these steps into precise linear displacements.

Q: What types of screws are used in linear screw stepper motors?

A: · Lead screws: Cost-effective but have higher friction and lower efficiency.
· Ball screws: More efficient, with lower friction and higher load capacity, but are more expensive

Q: How is the speed of a linear screw stepper motor controlled?

A: Speed is controlled by adjusting the pulse frequency (steps per second) sent to the motor driver. Higher frequencies result in faster motion, while lower frequencies slow it down. The motor's maximum speed depends on its torque capability and the load it drives.

Q: What factors affect the accuracy of a linear screw stepper motor?

A: · Step angle resolution: Smaller step angles improve accuracy.
· Screw pitch: Finer screw pitches increase resolution.
· Backlash: Minimized by using ball screws or preloaded nuts.
· Driver quality: High-quality drivers ensure precise pulse control.

Q: Can a linear screw stepper motor hold position without power?

A: Yes, due to the self-locking property of the screw mechanism. When the motor is powered off, the screw's thread prevents the nut from moving backward, maintaining position. However, this requires sufficient holding torque relative to the load.

Q: How do you select the right linear screw stepper motor for an application?

A: · Required speed and acceleration: Choose a motor with sufficient torque and step rate.
· Load capacity: Ensure the motor can handle the load without missing steps.
· Resolution: Match the screw pitch and step angle to the application’s precision needs.
· Environment: Select motors rated for the operating conditions.
