The modular design of the stator and rotor in the 85mm frameless motor, along with optimized slot ratios, improves the motor's torque density.
The rotor has a large inner bore space, and the stator is designed for embedded installation by the customer, facilitating personalized design including mounting structures and cooling systems, offering greater flexibility for custom systems.
The optimized slot-pole combination reduces motor cogging torque, ensuring smooth motor operation.
The structure is compact and highly integrated.
