DSH 40 Series Stepper Motor
The DSH40 series is a line of hybrid stepping motors from TECO with a frame size of approximately 40 mm, designed for compact motion-control applications. It belongs to the “DSH” family of stepping motors (as opposed to the “DST” family) and is targeted for systems with limited space and moderate torque requirements.
Key Features & Specifications
Frame Size: Approximate size is “40” (denoting ~40 mm body size) as indicated by the series name.
Electrical Configuration:
4-lead bipolar (series) and 6-lead unipolar wiring options are available.
Typical Models: For instance, “DSH40EX24A2K51000” is a variant listing used in inventory.
Nominal Characteristics: The spec sheet lists winding resistance, inductance, and rotor inertia for the DSH40 series.
Application Class: Compact indexing tables, small conveyors, light automation axes, feeders, or other systems where space and weight are constrained but step precision is still needed.
Advantages & When to Use
Compact & Lightweight: Its small frame size makes it suitable for tight spaces or applications that require multiple compact axes.
Precise Incremental Motion: As with other hybrid steppers, it provides a defined stepping motion (e.g., 1.8° step angle is standard, depending on variant).
Suitable for Open-Loop Systems: Many stepping motor uses do not require encoder feedback, making the DSH40 cost-effective for positional systems with moderate precision.
Connector/Variant Flexibility: With options in wiring (4-lead vs 6-lead) and possibly shaft/pulley attachments, it can be adapted to various mechanical setups.
Design Considerations
Torque vs Speed: As with all stepper motors, available torque will decrease at higher speeds. Engineers should consult the torque-speed curve for the DSH40 series when designing.
Load Inertia Matching: For best performance and to avoid lost steps, match the motor’s rotor inertia and capability to the driven load.
Driver Compatibility: Ensure the stepper driver supports the motor’s specified current, step, and direction (step/dir) signals, as well as the motor’s wiring configuration.
Control Mode: Microstepping can improve smoothness and resolution, but may reduce torque compared to full-step operation.
DSH 40 Series Stepper Motor
The DSH40 Series is a hybrid stepper motor line from TECO with a frame size of ~40 mm (“40” in the series name) designed for compact motion‐control applications. It’s intended for applications where precise incremental (step-by-step) motion is required and where cost or simplicity are more important than complete servo motors. The DSH40 Series Stepper Motor offers a compact, precision-stepping solution for automation applications that require accurate incremental motion in a small footprint. When properly matched and integrated, it provides a cost‐effective and reliable choice for many machine motion axes.
