Festo EMMB-ST Stepper Motors

Festo EMMB-ST Stepper Motors are designed for applications with basic requirements, such as machine builders in electronics, basic automation, and light assembly. These cost-effective devices can be combined with the CMMT-ST-MP servo drive controller to create an ideal servo system. The EMMB-ST series offers a simple and space-saving connection via Festo's one-cable plug (OCP) hybrid cable, which features a common motor and connection cable for both the supply and the encoder. An additional feature is the "electronic rating plate," which contains a motor correction table for precise control. The table also enables the motor to be optimally adjusted to achieve the desired performance. Festo EMMB-ST Stepper Motors feature IP40 protection for the motor shaft and IP65 for the motor housing, including connection technology.
