Beschreibung
The DS43mm Series FL is a frameless 43 mm BLDC motor family for compact direct-drive integration in embedded assemblies where low mass and installation flexibility are important. 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 with external control architecture, and the motor has no integrated feedback.
This motor uses an 18-slot, 10-pole-pair 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 is 4200 rpm, and peak capability reaches 0.3 N·m at 3.3 A. Electrical characteristics include 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 and 25 mm rotor ID for space-constrained designs
- Low moving mass with 50 g stator, 10 g rotor, and 20 g·cm² rotor inertia
- 31.5 W rated power with 0.1 N·m rated torque and 0.3 N·m peak torque
- Suited to humanoid robotics and other embedded systems using external feedback
The DS43mm Series FL is intended for applications such as humanoid robotics that need compact installation, moderate speed, and direct-drive motor integration inside a larger assembly. Its combination of small diameter, low rotor mass, and frameless format makes it suitable where the surrounding system defines the final mechanical package and feedback method.
