Frameless Motor rotor/stator unit 43ZWC15X-2

frameless48 V

Description
The modular stator and rotor design of the 43 mm frameless motor, combined with optimized slot ratios, increases torque density and reduces cogging for smooth operation. The rotor provides a large inner bore and the stator is intended for customer-embedded installation to enable customised mounting structures and cooling solutions.
