Motorized Linear Stages from Newport are designed and built using many decades of experience in providing solutions to many markets including research and academia, industrial, semiconductor, aerospace and defense. We also offer Nanopositioning Linear Stages based on piezo motor technology and Custom Multi-Axis Stack Solutions.
A motorized linear translation stage is used to precisely position an object along a single axis. Motorized linear stages include a moving platform and stationary base joined by a bearing system. Position is controlled electronically with the use of a motion controller. Motorized stages are preferred for high load/high speed applications, as well as applications where manual adjustment may be difficult. See Motion Basics and Standards for more information. We also offer Manual Linear Translation Stages that can be positioned using a micrometer head, adjustment screw or linear actuator.
The motor of a stage has a significant impact on its capabilities, performance and price. Newport offers a variety of motor types – stepper motors, DC motors, linear motors and piezos – within our standard products to best meet your application and budget. Other factors such as type of bearing, construction material, and position feedback also affect stage performance, but presented in this table is a general summary of performance by motor type:
| Motor Type | Travel | Speed | Resolution | Repeatability | Load | Price |
|---|---|---|---|---|---|---|
| Linear Motor | Long | Fast | High | High | High | $$$ |
| Brushless DC | Medium | Medium | Medium | High | High | $$ |
| DC Motor | Medium | Medium | Medium | Medium | High | $$ |
| Stepper Motor | Medium | Medium | Medium | Medium | Medium | $ |
| Piezo Motor | Short | Slow | High | Low | High | $$ |
For more details about motor type and other translation stage components, please see our Stage Components Considerations technical note.
Stepper motors are often used in open-loop control systems, a lower cost alternative to closed-loop DC servo systems. They operate using the basic principle of magnetic attraction and repulsion. Steppers convert digital pulses into mechanical shaft rotation. The amount of rotation is directly proportional to the number of input pulses generated, and speed is proportional to pulse frequency. Pulse count is a good indicator of position, and adding a shaft encoder can further improve performance.

DC motors are best characterized by their smooth motion and high speeds. They provide good efficiency and a high power/weight ratio. A brushed DC motor essentially consists of a rotor placed in a magnetic field, which causes rotation when current is applied to the motor windings. The rotational speed is proportional to the applied voltage, while the torque is proportional to the current. Precise closed-loop servo positioning and speed control is typically achieved with a shaft-mounted rotary encoder, and for ultra-precise positioning, a direct reading encoder on the drive train may be used. Note that unlike stepper motors, DC motors do not provide full torque when idle.

Linear motors consist of a permanent magnet assembly which establishes a magnetic flux, and a coil assembly which generates a force proportional to coil current. Linear motors have become very important components of precision positioning systems, with numerous advantages over traditional mechanical actuators such as ball screws. These systems typically provide higher quality, frictionless motion, and higher speeds and acceleration.
