Today, the humble stepper can offer surprising cost effectiveness with uncompromised performance at extra low voltage. The new, optimised EMMB-ST and EMMT-ST stepper motor family from Festo can be used in conjunction with the CMMT-ST servo drive controller to create a coordinated servo system at an attractive price. The stepper motor family includes models designed for regular and advanced industrial automation applications, enabling machine builders and system designers to choose the most cost-efficient option.
The EMMB-ST range of stepper motors is the basic series for regular industrial applications. This cost-effective model is particularly suitable for series machine manufacturers and applications in electronics and small parts handling. It features a One Cable Plug (OCP) cable that saves space and enables front or rear alignment. Providing reliable and cost-effective operation, EMMB-ST stepper motors are rated to IP20 (shaft IP40).
The premium range of EMMT-ST stepper motors are designed for applications that require a higher IP rating and outstanding levels of connectivity. This model is rated to IP65 (shaft IP40) and holds UL certification. It features an OCP cable with a solid M17 plug that can be rotated through 310°.
Festo’s EMMB-ST and EMMT-ST stepper motor family: in combination with the CMMT-ST servo drive controller, it offers users a coordinated servo system at an attractive price.
The compatible CMMT-ST servo drive controller supports multiple fieldbus protocols as standard as well as Safe Torque Off and Safe Stop 1 functions. The controller features an energy management function that can make the most ordinary positioning system more sustainable. For example, it can save energy in battery systems in Automated Guided Vehicles (AGVs), Autonomous Mobile Robots (AMRs), forklifts or small load carriers. At just 27mm wide and only needing a 24 or 48V DC power supply, the CMMT-ST controller offers a convenient choice for centralised or decentralised architectures.
Festo online selection and configuration tools, such as the Electric Motion Sizing Tool, mean that specifiers can select the right drive package quickly and reliably. Faster and easier commissioning is also possible using Festo’s Automation Suite (FAS) software.
Festo offers a starter kit containing a CMMT-ST controller with multi-protocol function, an EMMT-ST stepper motor and matching motor/encoder cables with OCP technology. It can be used to develop solutions for individual automation tasks and to test possible applications. The kit is easy to use and intuitive to install with the Festo Automation Suite software and provides the full range of functions. Also included is an hour of remote support from Festo’s expert applications team to give you a head start.
