100W Low-Voltage Servo Motor 40ASM100-5-17BCG-P with 17-Bit Encoder and Brake

Compact Precision for Small Axes

The 40ASM100-5-17BCG-P is a 100W Low-Voltage Servo Motor housed in a 40 mm frame and powered from a 24 VDC bus. It develops 0.32 N·m of rated torque at 3000 r/min, which makes it a practical fit for the small motion axes used in semiconductor handling, optics, inspection systems and laboratory instruments. For design engineers, this power class is attractive because it brings servo-grade positioning into an envelope that previously only allowed a compact stepper or a geared DC motor.

Absolute Feedback in a Small Package

Its 17-bit magnetic encoder delivers absolute position information without the extra space a separate home sensor would take up. That lets equipment designers build repeatable wafer-stage-like movements into dense instrument layouts, where every cubic centimetre counts. Because the feedback is magnetic rather than optical, it also resists the dust and humidity that are common around laboratory benches and clean-room support equipment.

Integrated Brake and Low-Voltage Safety

An integrated brake locks the shaft when power is removed, which is valuable on vertical fixtures in optics and inspection stations where the load must not drift. The 24 VDC supply keeps the whole axis within restricted low-voltage requirements, simplifying wiring, insulation ratings and safety margins in medical and laboratory environments.

Where It Is Used

This servo suits robotics end-effectors, semiconductor handling equipment, medical devices, laboratory automation, optical alignment stages, inspection machines and small pump systems that need precise, repeatable motion in a compact volume.

Selection Considerations

When specifying, check that the 0.32 N·m continuous torque covers the load at the speeds you actually run, and allow for the brake holding torque on vertical axes. Because the motor is compact, confirm that airflow around the frame is sufficient for the duty cycle. As a distributor, Lyenwsin supplies the 40ASM100-5-17BCG-P with matching drives and technical support, so you can confirm encoder and brake compatibility before production.
