Description
The DS115mm Series is a frameless BLDC motor family with a 115 mm stator outer diameter and Hall sensor feedback for 120° commutation. The listed version, 115ZWC37X-1, uses a 27-slot, 15 pole-pair electromagnetic design with star-connected windings, class F insulation, and S2 duty. Its frameless construction supports direct integration into compact drive assemblies where motor dimensions, rotor/stator matching, and system packaging are critical.
At 48 VDC, this motor delivers 570 W rated power, 3.9 N·m rated torque, and 1400 RPM rated speed, with no-load speed of 1750 RPM. Key electrical data include 0.122 Ω phase-to-phase resistance, 0.477 mH phase-to-phase inductance, 0.281 Nm/A torque constant, and 20.8 Vrms/Krpm back-EMF constant. The motor also provides 12.7 N·m peak torque at 47 A peak current, while rated current is 14.1 A. Electrical insulation data includes 1200 VAC / 3 mA / 1 s withstand voltage and 50 MΩ / 500 VDC insulation resistance.
- High torque density for integrated drives: 3.9 N·m rated and 12.7 N·m peak torque
- 48 VDC platform with 570 W output for medium-power motion systems
- Hall sensor feedback and 120° commutation for controlled BLDC operation
- Compact frameless geometry: 115±0.027 mm stator OD and 74+0.03 mm rotor ID
- Suitable for embedded motion assemblies requiring matched rotor/stator sets, with rotor inertia of 3930 g·cm²
The DS115mm Series is suited to integrated industrial motion systems that use frameless motor sets inside customer housings, transmission stages, or custom actuator structures. Its combination of compact 115 mm stator size, controlled BLDC feedback, 48 VDC operation, and strong rated-to-peak torque capability makes it appropriate for space-constrained servo-style drive applications that require stable speed, torque output, and direct mechanical integration.
