Frameless motors require a high degree of installation precision; if certain details are not handled properly, performance will be significantly compromised.
Inst allation precision is key: During installation, both the axial alignment error and coaxiality between the stator and rotor must be controlled within 0.1 mm.
You’ll need to configure the encoder yourself: The frameless motor itself generally does not come with an encoder; it is merely a motor core.
Installation orientation matters: An engineer once asked whether installing the stator and rotor in reverse (with the polarity reversed) would affect performance. Experience shows that as long as the relative axial position and clearance between the two remain unchanged, the only effect is a possible change in the direction of rotation; other electrical parameters remain largely unaffected.
