FESTO EMMT-ST Stepper Motors for Positioning Applications
The EMMT-ST series consists of stepper motors for automation applications such as feeding, dosing, axis movement, and other tasks where repeatability and motion control matter. Selecting the right EMMT-ST means matching the torque, operating conditions, and control system (driver/controller) so the motor runs reliably without missing steps.
How to Select an EMMT-ST for Your System
- Torque and safety margin: Assess the operating load and acceleration, and allow extra torque for peak loads and mechanical friction.
- Dimensions and mounting: Consider the flange, shaft, available space, mounting method, and compatibility with the mechanical system (axis, screw drive, or belt).
- Current and power supply: Match the motor to your driver and power supply (often 24 V or 48 V), taking heating and operating conditions into account.
- Control: Consider the driver type, microstepping, control modes, and integration with your PLC or motion controller.
- Options: A holding brake to hold position, an encoder for position feedback or closed-loop control, and a version suited to the operating environment.
Components Needed to Get the System Running
A working system usually needs a motor, driver/controller, power supply (if required), and cables/connectors. We can help select a compatible set for your application and mounting constraints.

FAQ: EMMT-ST Stepper Motors
How do I choose the right torque for an EMMT-ST?
Allow a torque margin for peak loads and acceleration. Share the mechanical specifications (load mass, travel, and speed), and we can help select a suitable motor.
When is a brake needed?
When the axis or load must be held in position without power, or when you need to prevent movement under gravity or external forces.
Do I need an encoder?
An encoder is useful when position verification or greater reliability through closed-loop control is needed for applications with dynamic loads.
Which supply voltage is better: 24 V or 48 V?
It depends on the driver and dynamic performance requirements. A higher supply voltage often improves performance at higher speeds, but compatibility and operating conditions determine the right choice.
Can you help select a driver/controller and cables?
Yes. We can select a compatible driver/controller, power supply, and cables for the specific EMMT-ST motor.
