Beschreibung
The DS43mm Series is a frameless 43 mm BLDC motor family for compact direct-drive integration in embedded assemblies where low mass and installation flexibility matter. The listed version, 43ZWC15X-2, is a 48 VDC motor with a 43 mm stator outer diameter and 25 mm rotor inner diameter. Its frameless construction supports custom mechanical integration and use with external control and feedback architecture, while the motor itself has no integrated feedback.
This motor uses an 18-slot, 10-pole-pair electromagnetic design with star connection, 120° commutation, insulation class F, and S2 duty. Rated output is 31.5 W at 3000 rpm, with 0.1 N·m rated torque at 1 A. No-load speed reaches 4200 rpm, and peak capability is 0.3 N·m at 3.3 A. Electrical data includes 3.4 Ω phase-to-phase resistance, 2.17 mH phase-to-phase inductance, a torque constant of 0.1113 Nm/A, and a back-EMF constant of 8.4 Vrms/Krpm.
- Frameless architecture for embedded direct-drive integration
- Compact 43 mm stator OD with 25 mm rotor ID for space-constrained designs
- Low moving mass with 50 g stator, 10 g rotor, and 20 g·cm² rotor inertia
- Balanced operating point: 31.5 W, 3000 rpm, and 0.1 N·m rated torque
- Suitable for humanoid robotics and other compact systems requiring moderate speed and external feedback selection
For insulation and reliability parameters, the motor is specified at 1200 VAC/3 mA/1 s withstand voltage and 50 MΩ/500 VDC insulation resistance. The DS43mm Series fits applications that need a lightweight frameless motor with moderate speed, compact dimensions, and flexible system-level integration.
