Beschreibung
DS38mm Series FL is a frameless 48 VDC BLDC motor family for compact direct-drive integration in embedded motion assemblies where low mass, space efficiency, and installation flexibility are important. All variants use a 38 mm stator outer diameter, 18 mm rotor inner diameter, 12-slot / 7-pole-pair design, star connection, 120° commutation, insulation class F, and S2 duty. The family has no integrated feedback and is intended for systems built around external control architecture.
This series combines compact frameless construction with high-speed operation. Across the listed variants, rated power ranges from 110 to 245 W, rated torque from 0.1 to 0.23 N·m, and rated speed from 10,190 to 10,470 RPM, with no-load speed up to 13,000 RPM. Peak torque reaches 0.32 to 0.76 N·m, with torque constants of 0.035 to 0.039 Nm/A and back-EMF constants of 2.6 to 2.88 Vrms/Krpm. Phase-to-phase resistance ranges from 0.14 to 0.8 Ω and inductance from 0.185 to 0.9 mH.
- Frameless 38 mm format supports direct embedding into custom drive assemblies.
- 48 VDC platform with up to 245 W rated output supports compact high-speed drives.
- Up to 13,000 RPM no-load speed suits fast rotary motion in space-constrained systems.
- Peak torque up to 0.76 N·m supports short-term overload capability.
- No integrated feedback fits applications using external sensing and control hardware.
Typical use is in compact embedded direct-drive systems that need low moving mass and flexible mechanical integration. Depending on the variant, stator weight ranges from 50 to 87 g, rotor weight from 10 to 20 g, and rotor inertia from 10 to 20 g·cm², supporting responsive motion in tightly packaged assemblies.
