OverviewThe modular stator and rotor design of the 43mm frameless motor, combined with optimized slot ratios, increases torque density. The rotor provides a large inner bore and the stator is intended for customer-embedded installation, enabling customized mounting structures and cooling solutions for greater system flexibility. The optimized slot-pole combination reduces cogging torque for smooth operation. The overall structure is compact and highly integrated.
