Introduction to Frameless Motor
Frameless motor is a highly integrated motor design that differs from traditional motors,
It omits the external casing and bearing structure, consisting only of two parts: the rotor component (magnetic steel+iron core) and the stator component (winding+iron core).
This design allows it to be directly embedded into the mechanical structure of the equipment, achieving a more compact and lightweight system layout through "mechatronics integration".  

Core parameters:
-Torque density: 5-30 Nm/kg (varies depending on the magnetic steel material and cooling method)
-Speed range: 500-20000 RPM (supports high-speed precision control)
-Power density: 1-5 kW/kg (more than 30% higher than traditional framed motors)
-Thermal management: relying on external cooling system, the operating temperature is usually ≤ 125 ℃

Structural features:
1. Rotor: High performance permanent magnets (such as neodymium iron boron) are used, which are directly fitted onto the load shaft and fixed by interference fit or adhesive.   
2. Stator: Without frame support, the winding is directly embedded in the equipment base and requires customized heat dissipation channels (such as water cooling slots).   
3. Feedback system: Integrated high-resolution encoder (such as 17 bit absolute value encoder) to achieve micrometer level positioning accuracy.  

Core advantages:
-Lightweight: eliminating redundant structures, reducing weight by 40% -60%
-High rigidity: The rotor is directly connected to the load shaft, eliminating transmission clearance and improving dynamic response
-Flexible customization: adaptable to irregular spaces, supporting multi axis parallel or hollow axis design

Application scenarios:
-Industrial field: Collaborative robot joints, CNC machine tool spindles, semiconductor wafer positioning platforms
-Aerospace: Flight control servos, satellite antenna drive mechanisms
-Medical equipment: surgical robots, MRI scanners, rotating parts
-New energy: electric drive system (wheel hub motor, electric spindle)

Usage method:
1. Mechanical integration: Directly press fit the rotor onto the load shaft (with controlled interference of ≤ 0.02mm), fix the stator on the equipment base and ensure uniform air gap (± 0.03mm).   
2. Thermal management: When forced cooling (such as circulating water cooling), it is necessary to seal and prevent leakage, and air cooling should reserve airflow channels.   
3. Control matching: Low harmonic drivers are required to suppress cogging torque fluctuations and set over temperature/overload protection.  

The frameless motor improves efficiency to over 97% by eliminating losses in the mechanical transmission chain, making it particularly suitable for high-end equipment fields with strict requirements for space, weight, and dynamic performance,It is an ideal choice for intelligent manufacturing and precision drive systems.

Note:
The thermal performance is closely related to the installation environment, and the rated working temperature is -40 ℃~125 ℃.
Theoretical no-load speed of rated voltage Ur; The use of different transformers may vary.
The maximum speed depends on the mechanical structure.
