Festo EMMT-ST Series Stepper Motor, 48V nominal operating voltage, 0.63Nm holding torque - EMMT-ST-42-L-RS, Numeric Part Number: 8156168

This stepper motor provides precise incremental motion control for industrial automation and motion systems. Designed for continuous operation, it combines a 1.8° step angle with an absolute single‑turn encoder and a hybrid plug electrical interface. The unit accommodates varied mounting orientations and offers environmental protection for the housing suitable for more demanding installation conditions.

Features and Benefits:

• 1.8° step angle enables accurate positioning for controlled movements
• 48 V nominal operating voltage supports higher torque delivery
• 3.4 A nominal current ensures sustained torque under load
• 3,200 rpm maximum rotational speed enables Faster cycle times
• IP65‑rated motor housing protects connections in dusty environments

Applications

• Suitable for precision indexing tables in assembly lines
• Ideal for pick‑and‑place mechanisms requiring repeatable motion
• Used with closed‑loop drives for servo‑type control tasks
• Can be used for conveyor positioning in production cells
• Suitable for laboratory automation requiring fine positional resolution

What encoder Interface does it use?

It uses a BiSS‑C absolute single‑turn encoder with 16‑bit resolution.

How is thermal management specified for continuous duty?

The motor has a thermal time constant of 16 min and a thermal resistance of 2 K/W for S1 rating.

What are the winding electrical characteristics?

Each phase has 0.6 Ω resistance and 0.8 mH inductance, with an electrical time constant of 1.3 ms.

What mechanical loads can the shaft tolerate?

The shaft accepts axial loads up to 10 N and radial loads up to 28 N.

How does altitude affect performance?

Above 1,000 m a derating of -1.0% per 100 m applies, with a maximum installation height of 4,000 m.
