Frameless Torque Motor Structure

Motor Pole and Slot Matching: Adopts a fractional-slot concentrated winding structure and a multi-pole multi-slot matching method, reducing end windings, decreasing the axial and overall dimensions of the motor, increasing the motor's power density, and reducing torque ripple;

 

Stator and Rotor Magnetic Circuit Structure: Uses a surface-mounted rotor structure to increase air-gap magnetic flux density and motor magnetic loading, thereby improving motor torque density; the outer shape of the permanent magnets in a surface-mounted permanent magnet motor is controllable, facilitating optimal design. By selecting a suitable outer shape for the magnets, the sinusoidal quality of the air-gap magnetic flux density can be improved, reducing magnetic field harmonics and contributing to a decrease in motor torque ripple.

 

Winding Structure: Uses magnetic materials with high saturation magnetic induction to increase the magnetic flux density in the stator teeth and yoke, further enhancing magnetic loading and reducing motor iron loss;

 

Excitation Unit Structure: Uses high-performance permanent magnetic materials as the motor rotor magnets to ensure that the motor can maintain high magnetic loading even at elevated temperatures;
