Beschreibung
Article 38ZWC22X-7 is a frameless 38 mm BLDC motor for compact direct-drive integration in embedded motion assemblies where low mass and installation flexibility are important. Designed for 48 VDC operation, it uses a 12-slot, 7-pole-pair electromagnetic layout with star connection, 120° commutation, insulation class F, S2 duty, and no integrated feedback. Its main dimensions are a 38 mm stator outer diameter and an 18 mm rotor inner diameter.
This version combines high speed with useful continuous and short-term torque capability. It delivers 245 W rated power at 10,190 RPM, with 0.23 N·m rated torque and 0.76 N·m peak torque at 24.2 A. No-load speed reaches 13,000 RPM. Electrical data includes 0.14 Ω phase-to-phase resistance, 0.185 mH phase-to-phase inductance, a torque constant of 0.039 Nm/A, and a back-EMF constant of 2.88 Vrms/Krpm. Low moving mass is supported by an 87 g stator, 20 g rotor, and 20 g·cm² rotor inertia.
- Frameless 38 mm format for direct integration into custom drive assemblies
- 245 W rated output with 13,000 RPM no-load speed for compact high-speed systems
- 0.23 N·m rated torque and 0.76 N·m peak torque for continuous and short-duty load demand
- Low rotor mass and 20 g·cm² inertia support responsive drive behavior
- Suited to compact high-speed direct-drive systems using external control and feedback architecture
The motor is intended for applications that require embedded installation, efficient use of space, and an external control and feedback architecture rather than integrated sensing. Its frameless construction makes it suitable for custom direct-drive designs where the motor is built into the surrounding mechanical assembly and where compact packaging and low moving mass are key design priorities.
