Hybrid Stepper Motor

Model Number: 34H2120-03S (Single-Shaft) & 34H2120-03D (Dual-shaft)
Serial Number: 072806688

Product Description:
The DINGS’ 34H2120 is a NEMA 34 (86×86mm) hybrid stepper motor, available in both single-shaft (34H2120-03S) and dual-shaft (34H2120-03D) configurations. Engineered for high torque and precision, it excels in medium-to-heavy-duty applications, providing excellent torque density and smooth operation across low-to-moderate speeds.

Key Specs & Features
- Frame: NEMA 34 hybrid stepper motor
- Step Angle Options: 0.9°, 1.8°, 0.76°—typical for hybrid motors
- Stack Variant: 120mm stack (designation “2120”)
- High Holding Torque: Up to ~20Nm (177in-lb) depending on stack length
- Construction: Bipolar winding, high torque at low speeds, minimal torque ripple
- Customizability: Options for encoders, IP-rated coatings, modified shafts, gearheads, and hollow shafts

Dimensional Highlights
