The EMMB-ST-42-L-SSB (part number 8156135) is a cost-effective two-phase hybrid stepper motor from Festo's EMMB-ST series, engineered for precise positioning applications with basic requirements, particularly suited for series machine builders and applications in electronics and assembly . With a nominal operating voltage of 48 VDC, a motor nominal power of 49 W, and a maximum rotational speed of 3200 rpm, it delivers reliable torque output for demanding positioning tasks . The motor features a 42 mm flange size and provides a nominal torque of 0.47 Nm, a peak torque of 0.63 Nm, and a motor holding torque of 0.63 Nm, ensuring secure load holding when stationary . It includes an absolute encoder (multi-turn, without battery) with a resolution of 16 or 17 bit depending on configuration, enabling precise rotor position feedback for closed-loop operation without the need for homing routines . The stepping angle is 1.8° with a tolerance of ±5%, and the motor supports a nominal current of 2.9 A with a peak current of 4 A . The SSB configuration specifically denotes the inclusion of a holding brake (24 VDC, 8.2 W), which secures the load when power is removed and is suitable for vertical or gravity-loaded axes . The motor uses a hybrid plug connector (connection pattern L5) for electrical connection and supports any mounting position. It is rated IP20 (IP40 for the shaft, IP65 for the motor housing including connection technology), operates across an ambient temperature range of -15 °C to 40 °C (with derating up to 80 °C at -2%/°C), and is RoHS compliant with PWIS conformity to VDMA24364-Zone III . The holding brake has a closing time of 41 ms and a separation time of 28 ms, with a rated switching cycle life of 10 million idle actuations . Typical applications include precision positioning stages, pick-and-place systems, indexing tables, and automated assembly stations where cost-effective, reliable stepper motor performance with encoder feedback and fail-safe holding brake functionality is essential. With its combination of 48 VDC operation, 49 W nominal power, absolute encoder, integrated holding brake, and compact 42 mm frame, the EMMB-ST-42-L-SSB delivers a dependable and versatile solution for precise motion control in demanding industrial automation applications.
