Description
Design Features
- Industry-standard NEMA frame stepper motors
- Available encoder feedback and brake options
- Models to run off of North American & Asian/European line voltages
- Optimized performance for use with Aerotech stages
- High-performance micro-stepping up to 50,000 steps/revolution
- Vacuum and cleanroom versions available
Design and Integration Flexibility
The SM series motors have been designed with optional direct encoder feedback, a holding brake, or even a viscous damper to improve the dynamic response of the rotor. These standard options allow the SM series to adapt to many common motion applications and extend their capabilities for use in a wider array of processes than a general stepper motor.
Line Voltage Capable
The NEMA 23 and NEMA 34 frame size SM series motors are available in a high-voltage optimized design. This produces optimum performance at both North American and European/Asian line voltages without the need for a transformer, further streamlining the system solution.
Dimensions
NEMA 17 [SM35]
NEMA 23 [SM60, SM100]
NEMA 34 [SM280, SM465]

Integration (Required)
Aerotech offers both standard and custom integration services to help you get your system fully operational as quickly as possible. The following standard integration options are available for this system. Please consult Aerotech if you are unsure what level of integration is required, or if you desire custom integration support with your system.
| Option | Description |
| -TAS | Integration - Test as system Testing, integration, and documentation of a group of components as a complete system that will be used together (ex: drive, controller, and stage). This includes parameter file generation, system tuning, and documentation of the system configuration. |
| -TAC | Integration - Test as components Testing and integration of individual items as discrete components that ship together. This is typically used for spare parts, replacement parts, or items that will not be used together. These components may or may not be part of a larger system. |
