DC rotor/stator unit 60ZWC25X-1

framelessfor frameless moduleFrameless Motor

Overview
The 60 mm frameless motor features a modular stator and rotor architecture with optimized slot-to-pole ratios to increase torque density and reduce cogging. The rotor provides a large inner bore for shaft or assembly integration. The stator is designed for customer-embedded installation, enabling tailored mounting frames and cooling solutions for OEM systems. The overall structure is compact and highly integrated.
