1.3．Smart ShaftIntroduction to Hollow Cup Servo Motor

Coreless Motor(Also known as slotless motor, ironless motor, hollow cup motor, slotless motor, ironless motor)The basic structure consists of a stainless steel stator with built-in high-energy permanent magnets and a rotor with precision coreless coils. Due to the fact that hollow precision windings can achieve the lowest rotor inertia and the highest slot occupancy rate, the stator flux is utilized most efficiently. Achieved high torque density and efficiency that are impossible to achieve in other servo motors.

SS（SmartShaft）The series hollow cup servo motor adopts the company's independent intellectual property "sine magnetic restraint（SMR）”The high-performance DC servo motor series has been successfully developed by combining technology with internationally advanced three-dimensional electromagnetic field finite element analysis technology. This type of motor has the following characteristics:
