Festo EMMT Series Stepper Motor, 42mm Frame Size, 1.8° Step Angle - EMMT-ST-42-L-RM, Numeric Part Number: 8156169

This stepper motor is a hybrid rotary actuator intended for precise positional control in industrial systems. It operates from a 48V supply and provides controlled rotary motion at high step resolution, suitable for panel-mounted installations in moderate environmental conditions. The design supports steady torque delivery and consistent electrical characteristics for motion-control applications.

Features and Benefits:

• 0.63Nm holding torque provides stable holding under load
• 3.4A current rating enables robust phase excitation
• 1000rpm output speed supports moderate-speed motion tasks
• 0.6Ω resistance per phase reduces phase voltage drop
• 50 pole pairs deliver high positional granularity

Applications

• Suitable for laboratory positioning stages requiring fine steps
• Ideal for automated valve actuators in control panels
• Used with motion controllers in pick-and-place systems
• Can be used for rotary indexing in assembly lines
• Suitable for educational CNC rigs and prototyping

What shaft specifications affect coupling choices?

The shaft is 5mm in diameter with 24mm protrusion to aid direct coupling and common clamp-style couplers.

How should the unit be mounted to a control enclosure?

It is designed for panel mounting and the IP40 rating indicates protection against solid objects larger than 1mm but not against water ingress.

Which electrical characteristic determines phase heating?

The 3.4A current rating together with 0.6Ω resistance per phase define I^2R losses that influence temperature rise during continuous operation.

What stepping resolution can be expected mechanically?

Each full step equals 1.8° providing predictable angular increments for open-loop control.

Are there limits to rotational speed for accuracy?

The motor’s specified output speed is 1000rpm

operating near this speed balances torque availability and step fidelity.
